Bearing identification

[rick]

Have had a bearing fail .... Deep Groove ball bearing type - metal shielded.

I know that normally metric bearings are exact mm sizes ..... and 2 of the measurements are in mm, but 3rd isn't. Assuming this is a metric bearing.

Online source I have tried (eg Simply Bearings do not have the size)

Measurements are

OD = 35mm (1.382") ID = 20mm (0.787") Thickness 10.59mm (0.417")

The thickness is not critical I can set deeper if thicker.

Anybody identify what this is, and if/where I can get one.

Little bit more work measuring the shafts ..... my best assumption is this bearing is

0.75" x 1.375" x 1/2" Deep groove ball bearing metal shielded

Any clue where to get one ?

Phone your nearest bearing supplier. Here, that would be Brammer Buck and Hickman.

I have emailed 3 of the big names ... see what turns up on Tuesday

I have to be honest and say I would be questioning how you're measuring this as the differences are too significant for finding the right bearing.

How are you measuring this, and do you have anything to hand to effectively calibrate your measuring stick? I would expect my measuring to be within 0.001" and have some degree of confidence with a digital vernier. Beware of cheap verniers, they also seem to have an error of

0.001" or more.

I didn't think 1.3/8" was a particularly common size? Your combination of dimensions doesn't seem to be available from:

I think you'll have more joy if you take this to a local specialist, although expect to pay twice as much as an online source. Sometimes the certainty is worth the cost.

I tend to agree. It would be helpful to know the application. If it is not an antique I'd suspect that it might be American. I'd be putting those dimensions into eBay and Google. If (say) it is a Briggs and Stratton you might find cheapest spares by including this in the search.
