Suppliers of miniature thin-section bearings?

hallmh · Oct 24, 2018

Hi - I am looking for a supplier of deep groove ball bearings with a very small section.

For example, bearing type 681 has bore 1mm, OD 3mm and is 1mm thick. The section is therefore 1mm x 1mm.

I would love to find a bearing with the same section size, but larger bore - I'm looking for 8mm ideally, but I can use anything around that size.

The closest I can find is MR128, which has a section 2mm x 2.5mm. Can anyone please suggest something slimmer? Thanks.

Hi, and thanks for the suggestion. Unfortunately, that one has a 6mm x 6mm section, so it isn't as slim as I'm looking for.

The slimmest bearing with a 10mm bore that I've found is type 61700, which has a 3mm x 3mm section.

Thanks again for taking the time to reply!

Hello,

Look into Kaydon ultra-slim bearings, with a cross section of 2.5 mm x 3 mm.

See page 84 of the following PDF catalogue:
