What is the equivalent of a 130127 bearing?

The 130127 is a 20×52×15mm self-aligning ball bearing with verified equivalents across multiple brands: FAG 6304, NSK 6304, NTN 6304, Timken 6304. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 130127 bearing?

The 130127 bearing has a bore diameter of 20mm, outer diameter of 52mm, and width of 15mm. It has a dynamic load rating of 16.8 kN, static load rating of 7.8 kN, and weighs 139g. Maximum speed with grease lubrication is 19,000 rpm.

Can I replace a SKF 130127 with a FAG equivalent?

Yes. SKF and FAG bearings with the same ISO designation are dimensionally interchangeable. The 130127 (20×52×15mm) can be replaced with the equivalent FAG 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.
