What is the equivalent of a NJ204W-C3 bearing?

The NJ204W-C3 is a 20×47×14mm cylindrical roller bearing with verified equivalents across multiple brands: NSK NJ204W C3, NTN NJ204ET2 C3, SKF NJ 204 ECP/C3, Timken NJ204EM/C3. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a NJ204W-C3 bearing?

The NJ204W-C3 bearing has a bore diameter of 20mm, outer diameter of 47mm, and width of 14mm. It has a dynamic load rating of 16.6 kN, static load rating of 13.9 kN, and weighs 111g. Maximum speed with grease lubrication is 12,000 rpm.

Can I replace a FAG NJ204W-C3 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The NJ204W-C3 (20×47×14mm) 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.
