What is the equivalent of a 6320 bearing?

The 6320 is a 100×215×47mm deep groove ball bearing with verified equivalents across multiple brands: NSK 6320, NTN 6320, SKF 6320, Timken 6320. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 6320 bearing?

The 6320 bearing has a bore diameter of 100mm, outer diameter of 215mm, and width of 47mm. It has a dynamic load rating of 174 kN, static load rating of 125 kN, and weighs 5280g. Maximum speed with grease lubrication is 3,000 rpm.

Can I replace a FAG 6320 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 6320 (100×215×47mm) 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.
