6202-2RZ vs 6202-2RS
6202-2RZ vs 6202-2RS
(OP)
Hello everyone! I am trying to replace a bearing in a bench grinder. The bearing that came in it is a 6202-2RZ bearing, and I cannot seem to find many retailers, and when I do, they have very high shipping costs, as they are all outside of the USA. I do, however, see a lot of 6202-2RS bearings. I did not seem to find any significant difference in the two bearings, but I also could not find both of them from the same distributor to compare. I was wondering if anyone could tell me what the difference is, if any, and if I would have any issue using a 6202-2RS instead of the 6202-2RZ.
Any help is appreciated. Thank you

S generally indicates contact lip seals.
The heat generated by contact seals can generate enough heat to limit the safe max speed of the bearing.
What is the rpm of this bench grinder?

Personally I'd use the sealed version with no qualms.
What is the OEM bearing manufacturer?
Grainger will sell singles of China sourced shielded bearings.

I meant to ask, why are you replacing one bearing ?

But with bearings this small, 3600rpm should not be a problem either way.
