What is the equivalent of a NU304-E-TVP2-C3 bearing?

The NU304-E-TVP2-C3 is a 20×52×15mm cylindrical roller bearing with verified equivalents across multiple brands: NSK NU304W C3, NTN NU304ET2 C3, SKF NU 304 ECP/C3, Timken NU304EM/C3. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a NU304-E-TVP2-C3 bearing?

The NU304-E-TVP2-C3 bearing has a bore diameter of 20mm, outer diameter of 52mm, and width of 15mm. It has a dynamic load rating of 31.5 kN, static load rating of 26.9 kN, and weighs 176g. Maximum speed with grease lubrication is 11,000 rpm.

Can I replace a FAG NU304-E-TVP2-C3 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The NU304-E-TVP2-C3 (20×52×15mm) 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.
