What is the equivalent of a 13031 bearing?

The 13031 is a 30×55×13mm self-aligning ball bearing with verified equivalents across multiple brands: FAG 6006-2ZR, NSK 6006ZZ, NTN 6006ZZ, Timken 6006-ZZ. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 13031 bearing?

The 13031 bearing has a bore diameter of 30mm, outer diameter of 55mm, and width of 13mm. It has a dynamic load rating of 13.8 kN, static load rating of 8.3 kN, and weighs 113g. Maximum speed with grease lubrication is 17,000 rpm.

Can I replace a SKF 13031 with a FAG equivalent?

Yes. SKF and FAG bearings with the same ISO designation are dimensionally interchangeable. The 13031 (30×55×13mm) 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.
