What is the equivalent of a 6043 bearing?

The 6043 is a 65×100×18mm deep groove ball bearing with verified equivalents across multiple brands: NSK 6013, NTN 6013, SKF 6013, Timken 6013. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 6043 bearing?

The 6043 bearing has a bore diameter of 65mm, outer diameter of 100mm, and width of 18mm. It has a dynamic load rating of 31.9 kN, static load rating of 25 kN, and weighs 426g. Maximum speed with grease lubrication is 8,000 rpm.

Can I replace a FAG 6043 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 6043 (65×100×18mm) can be replaced with the equivalent NSK part number as long as the seal type (open) and clearance class (CN) match. Always verify load ratings and speed limits for your specific application.
