What is the equivalent of a 319-SZZ bearing?

The 319-SZZ is a 95×200×45mm ball bearing with verified equivalents across multiple brands: NSK 6319ZZ, NTN 6319ZZ, SKF 6319-2Z, Timken 6319-ZZ. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 319-SZZ bearing?

The 319-SZZ bearing has a bore diameter of 95mm, outer diameter of 200mm, and width of 45mm. It has a dynamic load rating of 153 kN, static load rating of 108 kN, and weighs 4150g. Maximum speed with grease lubrication is 3,400 rpm.

Can I replace a FAG 319-SZZ with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 319-SZZ (95×200×45mm) can be replaced with the equivalent NSK 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.
