What is the equivalent of a 6203-2RSR bearing?

The 6203-2RSR is a 17×40×12mm deep groove ball bearing with verified equivalents across multiple brands: FAG 6203-2RSR, NSK 6203DDU, NTN 6203LLU, Timken 6203-2RS. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 6203-2RSR bearing?

The 6203-2RSR bearing has a bore diameter of 17mm, outer diameter of 40mm, and width of 12mm. It has a dynamic load rating of 9.95 kN, static load rating of 4.75 kN, and weighs 62g. Maximum speed with grease lubrication is 24,000 rpm.

Can I replace a SKF 6203-2RSR with a FAG equivalent?

Yes. SKF and FAG bearings with the same ISO designation are dimensionally interchangeable. The 6203-2RSR (17×40×12mm) can be replaced with the equivalent FAG part number as long as the seal type (2RS) and clearance class (CN) match. Always verify load ratings and speed limits for your specific application.
