What is the equivalent of a 1204JC3 bearing?

The 1204JC3 is a 20×47×14mm self-aligning ball bearing with verified equivalents across multiple brands: NSK 1204 C3, NTN 1204 C3, SKF 1204 ETN9 C3, Timken 1204 C3. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 1204JC3 bearing?

The 1204JC3 bearing has a bore diameter of 20mm, outer diameter of 47mm, and width of 14mm. It has a dynamic load rating of 9.36 kN, static load rating of 3.65 kN, and weighs 106g. Maximum speed with grease lubrication is 12,000 rpm.

Can I replace a FAG 1204JC3 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 1204JC3 (20×47×14mm) 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.
