What is the equivalent of a 30208-C3 bearing?

The 30208-C3 is a 40×80×19.75mm tapered roller bearing with verified equivalents across multiple brands: NSK HR30208J C3, NTN 4T-30208 C3, SKF 30208 J2/Q C3, Timken 30208 C3. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 30208-C3 bearing?

The 30208-C3 bearing has a bore diameter of 40mm, outer diameter of 80mm, and width of 19.75mm. It has a dynamic load rating of 34.9 kN, static load rating of 20.8 kN, and weighs 301g. Maximum speed with grease lubrication is 5,700 rpm.

Can I replace a FAG 30208-C3 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 30208-C3 (40×80×19.75mm) 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.
