What is the equivalent of a 6214DDU bearing?

The 6214DDU is a 70×125×24mm deep groove ball bearing with verified equivalents across multiple brands: NSK 6214DDU, NTN 6214LLU, SKF 6214-2RS1, Timken 6214-2RS. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 6214DDU bearing?

The 6214DDU bearing has a bore diameter of 70mm, outer diameter of 125mm, and width of 24mm. It has a dynamic load rating of 57.2 kN, static load rating of 36.5 kN, and weighs 720g. Maximum speed with grease lubrication is 6,300 rpm.

Can I replace a FAG 6214DDU with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 6214DDU (70×125×24mm) can be replaced with the equivalent NSK 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.
