What is the equivalent of a 1205227 bearing?

The 1205227 is a 17×40×12mm self-aligning ball bearing with verified equivalents across multiple brands: FAG 6203-2ZR, NSK 6203ZZ, NTN 6203ZZ, Timken 6203-ZZ. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 1205227 bearing?

The 1205227 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 1205227 with a FAG equivalent?

Yes. SKF and FAG bearings with the same ISO designation are dimensionally interchangeable. The 1205227 (17×40×12mm) can be replaced with the equivalent FAG part number as long as the seal type (ZZ) and clearance class (CN) match. Always verify load ratings and speed limits for your specific application.
