What is the equivalent of a 23120-12210 bearing?

The 23120-12210 is a 17×47×14mm ball bearing with verified equivalents across multiple brands: FAG 6303-2ZR, NSK 6303ZZ, NTN 6303ZZ, Timken 6303-ZZ. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 23120-12210 bearing?

The 23120-12210 bearing has a bore diameter of 17mm, outer diameter of 47mm, and width of 14mm. It has a dynamic load rating of 14.3 kN, static load rating of 6.55 kN, and weighs 110g. Maximum speed with grease lubrication is 22,000 rpm.

Can I replace a SKF 23120-12210 with a FAG equivalent?

Yes. SKF and FAG bearings with the same ISO designation are dimensionally interchangeable. The 23120-12210 (17×47×14mm) 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.
