What is the equivalent of a 30204-XL-C3 bearing?

The 30204-XL-C3 is a 20×47×15.25mm tapered roller bearing with verified equivalents across multiple brands: NSK HR30204J C3, NTN 4T-30204 C3, SKF 30204 J2/Q C3, Timken 30204 C3. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 30204-XL-C3 bearing?

The 30204-XL-C3 bearing has a bore diameter of 20mm, outer diameter of 47mm, and width of 15.25mm. It has a dynamic load rating of 15.2 kN, static load rating of 8.5 kN, and weighs 70g. Maximum speed with grease lubrication is 10,200 rpm.

Can I replace a FAG 30204-XL-C3 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 30204-XL-C3 (20×47×15.25mm) 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.
