Skate Bearings - Big Brother ???
Perhaps one of the absolute cheapest ball bearings assemblies is the
infamous skate bearing. They're cheap enough I buy them atleast a dozen at a time for misc projects, and just have them on hand. I probably have 30 or 40 of them in my spare bearings right, not and a small package of them in the center drawer of my desk. You can get them in better grades if you want to, but the plane old cheap import version holds up just fine for hundreds of projects, not the least of which is skate wheels. They are even cheaper than buying bronze bushings from most of the common industrial suppliers. I know. I have a few 8mm bore bronze bushings on hand too. I've wondered about this for years. I think I might even have asked this group before. Is there a big brother to this bearing? Something bigger and nearly as common so that it can be priced to keep a bunch of them on hand for miscellaneous project? |

Their catalog is a lesson in what's available in mechanical and hydraulic components. |

Hi, Bob. Can't answer the question. But, several years ago I bought a used/abused Chinese metal band saw at a local business "garage sale". $35.00. Keep it at the plant. Similar one at home. The abused one needed bearings. Checking for them on-line, I discovered the number matched the bearings for skate boards and bought a bunch on Ebay. Worked ok and saw is still going strong. My identical saw at home uses a different bearing number and I never check what the difference is. Paul |

They clog, but both the Z and RS are easy to open with a safety pin point to clean and regrease (or oil). |

All regular ball bearings are very cheap nowadays and even cheap ones
are well enough made for miscellaneous use. Enormous progress in making them cheaply and industrially. No need to hoard bearings, just buy them as you need them cheaply. i On 2019-07-23, Bob La Londe wrote: Perhaps one of the absolute cheapest ball bearings assemblies is the infamous skate bearing.

Enormous progress in making them cheaply and industrially. No need to hoard bearings, just buy them as you need them cheaply. i In Yuma, Az there is one major bearing reseller that I am aware of and the few times I have priced anything from them they seemed to think this was still the 1970s where I had the choice of buying from them or doing without. Other than that there are the usual hardware store bin bearings which are typically only small sheet metal ball bearings suitable for movement with light loads. There are a couple other sources, but they all say, "we can get it for you." Now I am not talking about a particular spec bearing to repair an old machine. For those I always get a high quality spec bearing to match the old one, and often I have to check multiple sources to find somebody who has it or has a good quality crossover. They are almost never cheap. In this case its more along the lines of deciding I want to build something. Usually in the evening or on the weekend when I have shut down production in the shop. Sure I can't have everything, but I can have a lot. Skate bearings are pretty amazing. 4 of them can handle a thousand pounds rolling load for a while, and a few hundred indefinitely with a quality grease. When you think about it that's insanely good for such a tiny little bearing. Put some preload on them and you can even make a light duty spindle out of them (I have) that's perfect for cross drilling or cross tapping on the lathe. I don't know how long they will last as my first one shows no signs of wear yet. I was just looking for a couple larger bearings I could spend a couple hundred bucks on and have a bunch of them in the project bearings drawer on my back assembly bench for those weekend inspiration projects. |

For me usually the shaft diameter determines the inch or metric bearing. Hardware store and second-hand pulleys are typically inch and may be difficult to rebore accurately, so they need inch shafts and bearings. When I make everything from scratch I can use metric sizes. Ultimately the motor torque or the axle load defines the minimum shaft diameter, see my thread on Lovejoy couplers. The temporary setups I've seen in engineering labs were often built from 80/20 extrusions and pillow blocks. The local bearing supply house told me 3/4" and 1" are the most common shaft sizes they sell for prototyping. |

I was just looking for a couple larger bearings I could spend a couple hundred bucks on and have a bunch of them in the project bearings drawer on my back assembly bench for those weekend inspiration projects. I like to salvage the shafts from gas struts. I'll put the horizontal 4"x6" outside, and set up the cut, then step back while they spray oil when they vent. The shafts are usually 6mm or 10mm, so matching bearings would be metric. I order some bearings from McMaster, or if I want special seals or materials like marine, I'll use Boca Bearing. They specialize in smaller bearings for r/c cars, fishing reels, etc. Pete Keillor |

I thought I said it in the first post that these are to have some on hand when I just want to "MAKE" something at night or on the weekend and not have to put it on the shelves of unfinish projects until the bearings come in. As long as it will handle the load I can always make a shaft fit a bearing. I think I also said when I am repairing a piece of machinery I just order a quality exact match bearing. I make things. LOL. I don't just fix things. I bought a small assortment of bearings for future projects and so far have used only the 608 skate bearings. At the time I thought I'd need 60xx bearings for small electric motor projects but now I build for gas engine power. When I built the sawmill I bought extra L095 couplers and spiders and considered stocking up on more 3/4" and 1" keyed shafting and pillow blocks. I haven't needed the shafting and had to change to larger L099 couplers. My hardware stock consists of a few pieces each of many sizes. I build with whatever I have on hand and then restock or buy better suited parts. |

(I really need to get more organized). I think they are the spindle nose bearing for one of my old wood routers. If its the one I recall it turned 28K. |
