What is the equivalent of a 6220C3-SQ77 bearing?

The 6220C3-SQ77 is a 100×180×34mm deep groove ball bearing with verified equivalents across multiple brands: NSK 6220 C3E, NTN 6220 C3, SKF 6220 C3, Timken 6220 C3. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 6220C3-SQ77 bearing?

The 6220C3-SQ77 bearing has a bore diameter of 100mm, outer diameter of 180mm, and width of 34mm. It has a dynamic load rating of 125 kN, static load rating of 93 kN, and weighs 2360g. Maximum speed with grease lubrication is 4,000 rpm.

Can I replace a FAG 6220C3-SQ77 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 6220C3-SQ77 (100×180×34mm) can be replaced with the equivalent NSK part number as long as the seal type (open) and clearance class (C3) match. Always verify load ratings and speed limits for your specific application.
