What is the equivalent of a 314KDD bearing?

The 314KDD is a 70×150×35mm ball bearing with verified equivalents across multiple brands: NSK 6314DDU, NTN 6314LLU, SKF 6314-2RS1, Timken 6314-2RS. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 314KDD bearing?

The 314KDD bearing has a bore diameter of 70mm, outer diameter of 150mm, and width of 35mm. It has a dynamic load rating of 104 kN, static load rating of 63 kN, and weighs 1720g. Maximum speed with grease lubrication is 4,800 rpm.

Can I replace a FAG 314KDD with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 314KDD (70×150×35mm) 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.
