What is the equivalent of a 73012085 bearing?

The 73012085 is a 55×120×29mm angular contact ball bearing with verified equivalents across multiple brands: FAG 6311-C3, NSK 6311 C3E, NTN 6311 C3, Timken 6311 C3. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 73012085 bearing?

The 73012085 bearing has a bore diameter of 55mm, outer diameter of 120mm, and width of 29mm. It has a dynamic load rating of 74.1 kN, static load rating of 45 kN, and weighs 1340g. Maximum speed with grease lubrication is 8,000 rpm.

Can I replace a SKF 73012085 with a FAG equivalent?

Yes. SKF and FAG bearings with the same ISO designation are dimensionally interchangeable. The 73012085 (55×120×29mm) can be replaced with the equivalent FAG part number as long as the seal type (open) and clearance class (C3) match. Always verify load ratings and speed limits for your specific application.
