What is the equivalent of a 1310EKTN9-C3 bearing?

The 1310EKTN9-C3 is a 50×108×23mm self-aligning ball bearing with verified equivalents across multiple brands: NSK 1310 C3, NTN 1310 C3, SKF 1310 ETN9 C3, Timken 1310 C3. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 1310EKTN9-C3 bearing?

The 1310EKTN9-C3 bearing has a bore diameter of 50mm, outer diameter of 108mm, and width of 23mm. It has a dynamic load rating of 29.8 kN, static load rating of 15.1 kN, and weighs 623g. Maximum speed with grease lubrication is 5,355 rpm.

Can I replace a FAG 1310EKTN9-C3 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 1310EKTN9-C3 (50×108×23mm) 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.
