What is the equivalent of a 1304E-TG bearing?

The 1304E-TG is a 20×56×16mm self-aligning ball bearing with verified equivalents across multiple brands: FAG 1304-TVH, NSK 1304, NTN 1304, Timken 1304. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 1304E-TG bearing?

The 1304E-TG bearing has a bore diameter of 20mm, outer diameter of 56mm, and width of 16mm. It has a dynamic load rating of 12.2 kN, static load rating of 4.7 kN, and weighs 148g. Maximum speed with grease lubrication is 10,200 rpm.

Can I replace a SKF 1304E-TG with a FAG equivalent?

Yes. SKF and FAG bearings with the same ISO designation are dimensionally interchangeable. The 1304E-TG (20×56×16mm) 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.
