What is the equivalent of a 22308 bearing?

The 22308 is a 40×90×33mm spherical roller bearing with verified equivalents across multiple brands: SKF 22308 E, NSK 22308EAE4, NTN 22308EMD1, Timken 22308EM. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 22308 bearing?

The 22308 bearing has a bore diameter of 40mm, outer diameter of 90mm, and width of 33mm. It has a dynamic load rating of 155 kN, static load rating of 140 kN, and weighs 1000g. Maximum speed with grease lubrication is 6,000 rpm.

Can I replace a FAG 22308 with a SKF equivalent?

Yes. FAG and SKF bearings with the same ISO designation are dimensionally interchangeable. The 22308 (40×90×33mm) can be replaced with the equivalent SKF 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.

22308

OpenCNSpherical Roller BearingSpherical Roller — Medium Series

Medium cross-section spherical roller bearings with higher load capacity than 22200 series for the same bore. Larger OD and greater width provide significantly more radial capacity. Standard sizes start at 22308 (40mm bore).
