Small, cheap, thrust bearing source
I need to make a live center for an old wood lathe that I have, and
need to find a smallish, inexpensive thrust bearing, say 1/2"+/- ID, 1"+/- OD. If it was near Seattle I could go and pick it up in person. Also, what kind(s) of thrust bearings will work? I'm clueless as to what to ask for. Are there sealed thrust bearings? Do I need to take radial loads into account as well as axial loads? Will one bearing work or do I need for each kind of load? |

I have made kind of a live center using a tapered roller bearing which
works for both radial and thrust loads. The bearing was a front wheel bearing. Where are you located? Dan Caster Kitsap County |

Likely you need a Morse taper.
The question is what one. If your thumb fits or just about (average thumb) - that is a Morse 2 Some old machines used Morse 1 and 0. You need to look up the spec - or tell us the mouth inside diameter. Up where you live - they have plenty in lumber yard / wood supplies stores. Look for skews and other wood working - likely to the side away - in a gold area - and the lugs that slam heavy hammers - not wanting to look at precision rules and the like.

Sears used to be my source for these for my old wood lathe, ran about
$6 for #1 and #2 Morse tapers. Designed for wood lathe service. I've seen them on the pegs in the larger stores, don't know what current cost is, though. Probably cheaper than messing with bearings and turning up centers, unless your time is worth nothing. Stan |

1) I live in Woodinville.
2) Thanks for the offers, but the reason I need to make a live center is because this lathe is quite old, and does'nt have a taper-mount live center. The head and tail stocks have flats and the spurs and centers slip on and are fixed by set screws. Clearly, the thing I need to do is buy a new (to me) lathe, but until I find the cure for cheapness I need to make my own parts. I though about a wheel bearing. What car model should I look for for a little one? |

Just ask for an A-1 bearing at any auto supply store.
That's the smallest common wheel bearing set. It's about 1.25" OD on the outer race IIRC. If you want to try a sealed ball bearing, the ubiquitous 203FF (203DD, 203SS) in a generic brand is about as cheap as you get. It's commonly used for idler pulleys and older alternator front bearings. If you get a blank stare from a teenager, try another store. - - Rex Burkheimer WM Automotive Fort Worth TX wrote: 1) I live in Woodinville. 2) Thanks for the offers, but the reason I need to make a live center is because this lathe is quite old, and does'nt have a taper-mount live center.

For small bearings you can't really beat roller skate bearings. There is a sports equipment rental outfit in Woodinville, can't remember their name, something like Play it Again Sam, anyway they rent rollerblades and as such they have to rebuild them and they have tons of old bearings. I once bought half a coffee can full for five bucks from them. Or you can buy new ones at the Target store in Woodinville, you get eight ABEC-7 bearings for like $14. That reminds me - I bought about 50 of them, half were new, for $1 at a garage sale last year. I had no use for them, but I couldn't pass up a deal :) |

Ah, McClendon's! One of the last real hardware stores. I almost never
go to the Borg anymore, and if I need to go to a big box store, I go to Lowe's. Not as rapacious as the Borg. Can roller blade bearings handle continous axial loads? The loading on a live center is primarily axial, I believe. |
