What is the equivalent of a NJ-209-ECP-C3 bearing?

The NJ-209-ECP-C3 is a 45×85×19mm ball bearing with verified equivalents across multiple brands: NSK NJ209W C3, NTN NJ209ET2 C3, SKF NJ 209 ECP/C3, Timken NJ209EM/C3. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a NJ-209-ECP-C3 bearing?

The NJ-209-ECP-C3 bearing has a bore diameter of 45mm, outer diameter of 85mm, and width of 19mm. It has a dynamic load rating of 46 kN, static load rating of 47 kN, and weighs 430g. Maximum speed with grease lubrication is 6,000 rpm.

Can I replace a FAG NJ-209-ECP-C3 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The NJ-209-ECP-C3 (45×85×19mm) 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.
