What is the equivalent of a 620414 bearing?

The 620414 is a 40×90×23mm deep groove ball bearing with verified equivalents across multiple brands: NSK NJ308W C3, NTN NJ308ET2 C3, SKF NJ 308 ECP/C3, Timken NJ308EM/C3. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 620414 bearing?

The 620414 bearing has a bore diameter of 40mm, outer diameter of 90mm, and width of 23mm. It has a dynamic load rating of 58.5 kN, static load rating of 57 kN, and weighs 650g. Maximum speed with grease lubrication is 6,000 rpm.

Can I replace a FAG 620414 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 620414 (40×90×23mm) can be replaced with the equivalent NSK part number as long as the seal type (open) and clearance class (C3) match. Always verify load ratings and speed limits for your specific application.

Technical Details & Applications

Specification variations and common equipment types.

Internal Clearance

Greater Than Normal (C3)

Increased radial internal clearance. Required when bearings operate at elevated temperatures or with tight shaft fits.

Temperature70-150°C operating temperature

Seal Type

Open (No Seal)

No seals or shields. Allows external lubrication and cooling. Lowest friction, highest speed capability.

Avoid forDirty, dusty, or wet environments. Applications without planned lubrication maintenance.
