Millrite MVI spindle bearing repair - first report
This is a continuation of the thread "Millrite MVI spindle bearings may need
replacement" first posted on 31 July 2010. I now have the spindle out of the quill and the taper roller bearings off the quill. I made (from a cast iron pipe fitting) a special pusher to avoid crushing the grease slinger, and (lacking a press) used a piece of 1/2-13 allthread passed through the drawbar hole to generate the needed force. Greasing the spindle just ahead of the sliding bearing race also helped. The taper roller bearings are not in that bad condition, given that the grease had turned into some kind of chalky cake. However, the absence of grease had allowed coolant to enter and corrode the bearing "cup" (the outer race) of the lower bearing assembly in a few places. I assume that the area weakened by corrosion will soon fail. The rollers are not yet clean enough to tell if they have been compromised, but one assumes that there has been damage. It is not obvious how one would grease these bearings without removing spindle from quill (which isn't that hard, but still). I have heard of people instead using DTE24 or heavier hydraulic oil fed in through the plug in the side of the quill, and letting it drip out of the bottom of the quill. This may be a better approach. What experience do people have with this? For the record, the two outer races ("cups") are each Timken 19268; and thetwo assemblies of inner races ("cones"), rollers, and cages are each Timken 19150. The stated ID of a 19150 cone is 1.5000". The quill shaft is about 0.0011" larger than the stated cone ID, so it was a light press fit. As others have noted , this cripples the running preload adjustment by turning a ring nut on the spindle, and press fits are too hard to get exactly correct. Is there a standard solution? I'm tempted to polish the spindle shaft down until the (new?) bearings are a (hand) push fit. Has anyone done this? Joe Gwinn |

The ID of a class 0 precision cone is nominal +13/+0 microns, with a resulting 5 to 30 micron interference. Personally, I wouldn't mess with the bearing seats. Even if you can maintain cylindricity, you're risking fretting of the seat if the fit is not tight enough. Be aware that the specs on standard tapered rollers are very loose compared to inexpensive ball bearings, and precision class bearings are quite expensive. Expect to pay around $270 for each cup/cone ass'y in class 0 vs. $45 for a standard bearing. BTW, the first thousand or so J-head Bridgeports used tapered rollers on the spindle; the subsequent couple hundred thousand have angular contact bearings. -- Ned Simmons |

Joe Gwinn There are people probably a lot more knowledgeable on this subject, but here’s my two cents. When you’re pressing the bearing into place, you’re putting the load on the outer race. When you tighten the ring nut, it preloads the inner race and rollers. The force used getting the bearing set in the bottom of bushing shouldn’t come into play. (If the bushing was too tight, I suppose that you might crack the bushing or outer bearing race.) I’ve put in a grease-fitting in the rod end of an old Keller power hacksaw that I’ve refurbished and it seems to have worked well. I think that my repair will make it last much longer, but what you probably have to guess is the level of stresses in the area supporting the bearing. If you drill there to put an oil cup or grease fitting, you could possibly cause a stress riser. If the bearing support is low-stressed, you’re probably safe to drill & tap it to add a lubrication fitting. |

D.C.Morrison says that if one just puts the grease in at the quill side port, it will work itself into the roller bearings (which are open). No harm in trying. Joe Gwinn |

But there are tradeoffs, such as added complexity, expense, and less tolerance of contamination. All true, and Burke apparently valued robust more than Bridgeport. Perhaps the intended audiences were different. Not that I've heard of Bridgeport spindles being so fragile. But I don't know why Burke didn't provide more protection against the entry of dirt and coolants. BP spindles are not especially well protected, either. The nose pair is protected only by a labyrinth formed by close clearances between the various parts of the spindle and quill. Indiscriminate use of air to clear chips can force crud up into the bearings. |

So the tap fit is the compromise. Does Timken mention alignment of high spots and low spots to reduce runout? Not that I see in the literature I have, but "Timken Bearings for Machine Tools" is mentioned in the section on precision bearings, and may have more info if you can find a copy online. I'm not finding anything by this name; perhaps this was an earlier version and/or name. What I did find is "Timken Super Precision Bearings for Machine Tool Applications", file "5918_09-09-29.pdf", 259 pages. The pages are all marked "TIMKEN MACHINE TOOL CATALOG" at the bottom. This is a very useful document, from the look of it. On page 100, they start to talk about aligning the high spots in exactly the same terms as I have been hearing, and later there is a picture showing what the high-spot marks look like. I found such marks on the bearings in my mill. Well, I'm short one mark (on a cup), which mark seems to have been abraded off. "Tap fit" is a rather subjective way to characterize a bearing fit, depending on who's doing the tapping and the size of the tapper, but I assume it means a transitional fit with minimal interference. The ID of your cones can vary by 5 tenths, so a tap fit on one bearing may result in excessive clearance on another. This may be what is happening. And things may have corroded and so grown a bit over the years. I think I'll do most of the polishing on the bearing ID, rather than the shaft OD, although I'll clean corrosion off the shaft. I certainly wouldn't hesitate to cautiously remove any corrosion or high spots you find. Yes. This weekend. Be aware that the specs on standard tapered rollers are very loose compared to inexpensive ball bearings, and precision class bearings are quite expensive. Expect to pay around $270 for each cup/cone ass'y in class 0 vs. $45 for a standard bearing. Which class is a "standard bearing"? I'd guess 4, for wheel bearings. Yes. What are "airplane bearings", like from skygeek.com? They are priced at the $45 level for the cup and another $45 for the cone et al. I don't know what "airplane bearings" are, but Motion Industries also references "aircraft bearings" in their database, with no indication of what distinguishes them from standard bearings. But they are listed as "standard precision." Another poster (J.Clarke) said that it meant only that the maker had jumped the hoops to become FAA certified for airplane repair. What is a typical price for Class 3 set of one 19268 and one 19150? Looks like about $125 for the cone and $68 for the cup. Those are my approx prices from Motion Industries. Oof. That's a total of 2(125+68)= 386= $400. I was leaning towards letting it be for now, and this is pushing me that direction. There is only one corroded spot, about 0.25" in diameter. What class is needed for a MVI anyway? Class TIR 4 .0020 2 .0015 3 .0003 0 .00015 00 .000075 The runout of Class 0 roller bearings is approximately the same as the ABEC 7 angular contact bearings typically found in machine tool spindles. DC Morrison says that Timken Class 3 are what was specified for the Millrite spindle, and the existing bearings are in fact marked 3. BTW, the first thousand or so J-head Bridgeports used tapered rollers on the spindle; the subsequent couple hundred thousand have angular contact bearings. Burke used taper roller bearings for the standard R8 spindle, and ball bearings for the high-speed spindle. Taper roller bearings are more robust than ball bearings under shock loads (like interrupted cuts). True, but BP spindle bearings will take a lot of abuse if they're lubricated properly and kept clean. Tapered rollers will carry a substantially heavier load than angular contact bearings in a given volume.

The nose pair is protected only by a labyrinth formed by close clearances between the various parts of the spindle and quill. The Millrite also has a labyrinth of sorts, being three ~square cross section grooves in the quill nut through which the spindle nose protrudes. It's a tight fit. Sounds like the BP approach. The grooves were packed full of crud, now removed. Indiscriminate use of air to clear chips can force crud up into the bearings. Yet another reason for the tradition to forbid use of compressed air on machine tools. Joe Gwinn |

For instance. If we fitted class 2 set of bearings and then finish ground the spindle nose and bore in situ, would we have a class 00 sytem? Jim |

So you cant even follow your own world view...hummm Idiot Savant..... Now back to the debt thingy Nut....what else do I own money on? Be specific. Medical bills and property taxes (which Im catching up on btw). Can you add any other debt issues I may have overlooked? The house is paid for, all my vehicles are paid for, all my tvs, appliences, furniture, toys and machinery are paid for. Ive not owned a credit card for 20 yrs..by choice. I dont even owe my ex wife a dime. So Teddly...what "prediciment" am I in? Other than being a 56 yr old machine tool repair tech in a state with a failing/nearly destroyed by the Left, machine tool industry? Be specific, use as much whitespace as you find appropriate. You do know that Social Security actually came to me and asked me if I wanted to go on the SS roles, right? That pesky Stroke I planned after the heart issue (and THAT took some real timing let me tell you!!) put me right into the willing arms of the SS crowd...100% disability from what they told me. They came right into my room at the hospital and brought in the papers for me to sign and get medical disability!! The little gal was a bit put out when I laughed at her and told her to save it for someone who actually needed it..like one of your beloved illegal aliens. So I guess I planned everything for naught, didnt I? Eat **** Neddy. You know you really want to. I just hope that those minding the List..dont take you as an unredeemable Leftard. If they do...Ill **** on your grave if I ever get to your neighborhood. Peoples Republik of Santa Monica, isnt it? Now was there anything else you wish to spew about? If not..Ive got planning to do for the next Big Welfare intitilement that Im going to nail California on. After all..better me than a family of wetbacks from Guatamala..!!!! Foolish or stupid would be me changing my business practices based on your advice. If you want to fight about something..pick something else you may have some ability to keep up with. Yeah, right. I hope your headstone is nice and porous..so it will hold **** for a long time. Now for the rest of you guys who send emails instead of calling...do as you choose. Ted may have some things that will attract the attention of those buffoons reading emails that you dont. Other than buffoonery of course. He is a "regular customer". He might even get a response. Im curious though..how many of you who have sent off emailed questions..have gotten a reply as of yet? Please, let us know. Prove me wrong!! I implor!! I beg you!! Gunner, who gets a response EVERY time he calls. I am the Sword of my Family and the Shield of my Nation.

If driving around to vendors and phoning in orders works for you that's great, it doesn't for me. Using the phone is "driving around"? Unless you have a vendor within walking distance, "face to face" implies driving around. Or do you take the bus? So there is some reason the first option..the voice to voice one is a non starter and is utterly ****ing ignored here? I gave you my reason a couple days ago, if you bothered to read it. Don't bother going back, I'll make it easy. "A typical PO of mine to Motion Industries may have upwards of 20 line items. Some of those lines will be made-to-order items with 40+ character part numbers. Calling in that kind of of order is error prone and makes absolutely no sense." Or are you gentlemen simply trying to look not only foolish..but stupid as well? I've been successfully running small engineering design and manufacturing businesses for 30 years. On the other hand, you spend your time blaming your predicament on the government, your family, liberals, and anyone else to hand. While you've been running up debts, I've been paying my bills, maxing my retirement, and paying college tuition for my son. Good for you Ted! Though I'd appreciate some cites on your claims I blame "my prediciment" on "the government, my family, liberals and "anyone else at hand" As for my running up debts...I obviously planned on that medical issue, didnt I? I waited for the worst possible time...planned for years, waited for the economy to go right into the ****ter..and then plugged up my arteries and drove myself to the hospital...just so I could take some medical expenses away from your valued and cherished hordes of illegal aliens. All planned!! Buwahahaha!! Planned and executed perfectly! And I got into treatment ahead of a waiting room filled with non english speakers here illegally with runny noses!!! Yesss!!!

I stated quite clearly to everyone..that if they want clear answers NOW..they should call, not wait around for a returned email..that may never come. Ned of course then puffed up his chest and blithered about how he ONLY emails yada yada. The implication of course is that Im utterly full of **** and he does Xnumbers of dollars worth of business from his known suppliers only via email. The question of course was not how much business one does with a known vendor, but getting actual answers on questions from new companies one is trying to get info from. I constantly see people emailing..then never getting anything done, because they dont get clear and immediate answers. I see this here, I see this in the Real World. I repair a variety of machinery. Some of which will require parts. You will NEVER find me emailing the sources of those parts, because frankly..the client needs the machine fixed ASAP, not next week, next month, next year. I make a living on getting machinery repaired as soon as possible. And Id have been out of business long ago if I had to depend on email. Shrug. Ned is .......Ned. Which is one of the reasons I dont pay all that much attention to him, though I do read all of his posts. Im sure he feels the same way about me. Such is life. Yawn.
