What is the equivalent of a 6018-ZZD bearing?

The 6018-ZZD is a 90×140×24mm deep groove ball bearing with verified equivalents across multiple brands: NSK 6018ZZ, NTN 6018ZZ, SKF 6018-2Z, Timken 6018-ZZ. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 6018-ZZD bearing?

The 6018-ZZD bearing has a bore diameter of 90mm, outer diameter of 140mm, and width of 24mm. It has a dynamic load rating of 55.3 kN, static load rating of 46.5 kN, and weighs 1080g. Maximum speed with grease lubrication is 5,600 rpm.

Can I replace a FAG 6018-ZZD with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 6018-ZZD (90×140×24mm) can be replaced with the equivalent NSK part number as long as the seal type (ZZ) and clearance class (CN) match. Always verify load ratings and speed limits for your specific application.
