What is the equivalent of a 1210ETN9-C3 bearing?

The 1210ETN9-C3 is a 50×90×20mm self-aligning ball bearing with verified equivalents across multiple brands: NSK 1210 C3, NTN 1210 C3, SKF 1210 ETN9 C3, Timken 1210 C3. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 1210ETN9-C3 bearing?

The 1210ETN9-C3 bearing has a bore diameter of 50mm, outer diameter of 90mm, and width of 20mm. It has a dynamic load rating of 22.9 kN, static load rating of 11.6 kN, and weighs 445g. Maximum speed with grease lubrication is 6,300 rpm.

Can I replace a FAG 1210ETN9-C3 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 1210ETN9-C3 (50×90×20mm) 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.
