What is the equivalent of a 13006X bearing?

The 13006X is a 50×110×27mm self-aligning ball bearing with verified equivalents across multiple brands: NSK NU310W, NTN NU310ET2, SKF NU 310 ECP, Timken NU310EM. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 13006X bearing?

The 13006X bearing has a bore diameter of 50mm, outer diameter of 110mm, and width of 27mm. It has a dynamic load rating of 87 kN, static load rating of 86 kN, and weighs 1140g. Maximum speed with grease lubrication is 4,800 rpm.

Can I replace a FAG 13006X with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 13006X (50×110×27mm) can be replaced with the equivalent NSK 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.
