What is the equivalent of a 30-20861 bearing?

The 30-20861 is a 20×47×14mm ball bearing with verified equivalents across multiple brands: FAG 6204, NSK 6204, NTN 6204, Timken 6204. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 30-20861 bearing?

The 30-20861 bearing has a bore diameter of 20mm, outer diameter of 47mm, and width of 14mm. It has a dynamic load rating of 13.5 kN, static load rating of 6.55 kN, and weighs 102g. Maximum speed with grease lubrication is 20,000 rpm.

Can I replace a SKF 30-20861 with a FAG equivalent?

Yes. SKF and FAG bearings with the same ISO designation are dimensionally interchangeable. The 30-20861 (20×47×14mm) 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.
