Hi guys, I`m after five x 1/8" ID Bearings - ideally the spec in the plans is 1/8" ID, 3/8"OD and 7/64" width. I`ve searched now for near 2 hours over the last week and I found one supplier who wanted £10 per bearing, with 5 to purchase I just can`t afford £50!! I`ve tried all the usual suspects, bearings boys, simply bearings (although struggled as their site was slow) and ebay with no luck. I don`t know if anyone knows a good stockest who might have them. I`m not looking for the exact spec, obviously the 1/8" ID is critical but I can fit around the other dimensions. I know imperial are likely to be more than metric sizes but I can`t justify paying silly prices when I can get 3mm ID bearings cheap. Obviously then I have to start changing plans and I don`t fancy that with this built, especially in 5 different places where the bearings fit! Hope someone can point me in the right direction.

Arceuro? Doesn't look like they've quite got that size - but some fairly close. http://www.arceurotrade.co.uk/Catalogue/Bearings/Ball-Bearings/Ball-Bearings---Imperial |

Bearing station have some for £5.33/ea, albeit with a fatness of 5/32" rather than the 7/64" you'd prefer. Still not cheap, I'll grant you, I guess imperial bearings must have gone right out of fashion. |

Chris -- The standard for American R-type bearings is .125 (1/8) ID X .375 (3/8) OD X .156 (5/32) W. At 7/64 (.109) W, the bearing ball is going to be quite small and have a very large Hertzian contact stress multiplier. I have to go back to 1977 to find a 7/64 W bearing listed in a catalog (and I have 2 ft worth of bearing catalogs on my bookshelf). IF you can accommodate the extra 3/64 (.047) width, I would change to an R-type (deep groove, inch measure) ball bearing. They run about $3.75-$4.00 ($1.60/L) at booth of my local bearing houses. |
