What is the equivalent of a 6317C3 bearing?

The 6317C3 is a 85×180×41mm deep groove ball bearing with verified equivalents across multiple brands: NSK 6317 C3E, NTN 6317 C3, SKF 6317 C3, Timken 6317 C3. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 6317C3 bearing?

The 6317C3 bearing has a bore diameter of 85mm, outer diameter of 180mm, and width of 41mm. It has a dynamic load rating of 133 kN, static load rating of 90 kN, and weighs 3000g. Maximum speed with grease lubrication is 3,800 rpm.

Can I replace a FAG 6317C3 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 6317C3 (85×180×41mm) 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.

Examples

Machine tool spindles
Gearboxes with oil bath lubrication
