What is the equivalent of a 61004 bearing?

The 61004 is a 50×80×16mm deep groove ball bearing with verified equivalents across multiple brands: FAG 6010-2ZR, NSK 6010ZZ, NTN 6010ZZ, Timken 6010-ZZ. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 61004 bearing?

The 61004 bearing has a bore diameter of 50mm, outer diameter of 80mm, and width of 16mm. It has a dynamic load rating of 22.9 kN, static load rating of 16 kN, and weighs 172g. Maximum speed with grease lubrication is 11,000 rpm.

Can I replace a SKF 61004 with a FAG equivalent?

Yes. SKF and FAG bearings with the same ISO designation are dimensionally interchangeable. The 61004 (50×80×16mm) 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.
