What is the equivalent of a 1209 bearing?

The 1209 is a 45×85×19mm self-aligning ball bearing with verified equivalents across multiple brands: FAG 1209-TVH, NSK 1209, NTN 1209, Timken 1209. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 1209 bearing?

The 1209 bearing has a bore diameter of 45mm, outer diameter of 85mm, and width of 19mm. It has a dynamic load rating of 22.9 kN, static load rating of 11 kN, and weighs 400g. Maximum speed with grease lubrication is 7,000 rpm.

Can I replace a SKF 1209 with a FAG equivalent?

Yes. SKF and FAG bearings with the same ISO designation are dimensionally interchangeable. The 1209 (45×85×19mm) 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.
