What is the equivalent of a 7304-2RS-C3 bearing?

The 7304-2RS-C3 is a 20×52×15mm angular contact ball bearing with verified equivalents across multiple brands: NSK 7304A-2RS C3E, NTN 7304-2RS/C3, SKF 7304 BE-2RZP C3, Timken 7304-2RS C3. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 7304-2RS-C3 bearing?

The 7304-2RS-C3 bearing has a bore diameter of 20mm, outer diameter of 52mm, and width of 15mm. It has a dynamic load rating of 14.31 kN, static load rating of 6.24 kN, and weighs 89g. Maximum speed with grease lubrication is 11,900 rpm.

Can I replace a FAG 7304-2RS-C3 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 7304-2RS-C3 (20×52×15mm) can be replaced with the equivalent NSK part number as long as the seal type (2RS) 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

Rubber Sealed (2RS)

Rubber contact seals on both sides. Superior protection from contaminants. Pre-lubricated, maintenance-free.

Avoid forVery high-speed applications (seal friction limits top speed). Environments exceeding 110°C.
