What is the equivalent of a 6003-2RSR bearing?

The 6003-2RSR is a 17×35×10mm deep groove ball bearing with verified equivalents across multiple brands: SKF 6003-2RS1, NSK 6003DDU, NTN 6003LLU, Timken 6003-2RS. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 6003-2RSR bearing?

The 6003-2RSR bearing has a bore diameter of 17mm, outer diameter of 35mm, and width of 10mm. It has a dynamic load rating of 6.37 kN, static load rating of 3.25 kN, and weighs 37.5g. Maximum speed with grease lubrication is 28,000 rpm.

Can I replace a FAG 6003-2RSR with a SKF equivalent?

Yes. FAG and SKF bearings with the same ISO designation are dimensionally interchangeable. The 6003-2RSR (17×35×10mm) can be replaced with the equivalent SKF part number as long as the seal type (2RS) and clearance class (CN) match. Always verify load ratings and speed limits for your specific application.
