Finding unmarked bearings

jkilroy · Apr 6, 2006

Anyone know an online source that can cross ref bearings by dimension?

Got this bearing, looks like a double row angular contact, sealed one side. No numbers anywhere to be found. Came out of one side of the variable speed pulley on my Rivett. Tired of that damn rattle.

Dimensions as follows.

ID = 1.77
OD = 1.345
W = 1.285

Change the dimensions to Metric and then it is esasy to find a suitable bearing.

ID = 1.77
OD = 1.345
W = 1.285

Thats one of those real special ones - the hole is bigger than the OD!! :cool:

That will be a hard bearing to find, as the ID is *bigger* than the OD, probably invisible. Seriously though you probably meant 3.345. This is where I look:

If that doesn't do it for you call Tom at BDI inc. 518-862-9854, he can match any bearing known to man up from dimensions and descriptions.

good luck.

Sorry fellas, 3.345 is correct. Converted to nearest mm it looks like this

ID = 45mm
OD = 85mm
W = 33mm

Went to that SKF web site (Thanks for that link the site rocks) and there is a very close match (all but width) Part number 5209 A 2RS C3 BRG. Motion industries lists that part at $101
