What is the equivalent of a 620413 bearing?

The 620413 is a 50×110×27mm deep groove ball bearing with verified equivalents across multiple brands: NSK NJ310W C3, NTN NJ310ET2 C3, SKF NJ 310 ECP/C3, Timken NJ310EM/C3. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 620413 bearing?

The 620413 bearing has a bore diameter of 50mm, outer diameter of 110mm, and width of 27mm. It has a dynamic load rating of 87 kN, static load rating of 86 kN, and weighs 1140g. Maximum speed with grease lubrication is 4,800 rpm.

Can I replace a FAG 620413 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 620413 (50×110×27mm) 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.

Examples

Machine tool spindles
Gearboxes with oil bath lubrication
