What is the equivalent of a 7310-C3 bearing?

The 7310-C3 is a 50×110×27mm angular contact ball bearing with verified equivalents across multiple brands: NSK 7310A C3E, NTN 7310 C3, SKF 7310 BEP C3, Timken 7310 C3. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 7310-C3 bearing?

The 7310-C3 bearing has a bore diameter of 50mm, outer diameter of 110mm, and width of 27mm. It has a dynamic load rating of 68.2 kN, static load rating of 47.9 kN, and weighs 1040g. Maximum speed with grease lubrication is 6,000 rpm.

Can I replace a FAG 7310-C3 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 7310-C3 (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
High-speed precision equipment
