What is the equivalent of a NU306E-TGP1-C3 bearing?

The NU306E-TGP1-C3 is a 30×72×19mm cylindrical roller bearing with verified equivalents across multiple brands: NSK NU306W C3, NTN NU306ET2 C3, SKF NU 306 ECP/C3, Timken NU306EM/C3. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a NU306E-TGP1-C3 bearing?

The NU306E-TGP1-C3 bearing has a bore diameter of 30mm, outer diameter of 72mm, and width of 19mm. It has a dynamic load rating of 53 kN, static load rating of 50 kN, and weighs 398g. Maximum speed with grease lubrication is 7,500 rpm.

Can I replace a FAG NU306E-TGP1-C3 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The NU306E-TGP1-C3 (30×72×19mm) 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.
