What is the equivalent of a 32004 bearing?

The 32004 is a 20×42×15mm tapered roller bearing with verified equivalents across multiple brands: FAG 32004-XL, NSK HR32004J, NTN 4T-32004, SKF 32004 J2/Q. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 32004 bearing?

The 32004 bearing has a bore diameter of 20mm, outer diameter of 42mm, and width of 15mm. It has a dynamic load rating of 12 kN, static load rating of 7 kN, and weighs 50g. Maximum speed with grease lubrication is 11,400 rpm.

Can I replace a Timken 32004 with a FAG equivalent?

Yes. Timken and FAG bearings with the same ISO designation are dimensionally interchangeable. The 32004 (20×42×15mm) 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.
