What is the equivalent of a 6320M1-C3 bearing?

The 6320M1-C3 is a 100×215×47mm deep groove ball bearing with verified equivalents across multiple brands: NSK 6320 C3E, NTN 6320 C3, SKF 6320 C3, Timken 6320 C3. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 6320M1-C3 bearing?

The 6320M1-C3 bearing has a bore diameter of 100mm, outer diameter of 215mm, and width of 47mm. It has a dynamic load rating of 174 kN, static load rating of 125 kN, and weighs 5280g. Maximum speed with grease lubrication is 3,000 rpm.

Can I replace a FAG 6320M1-C3 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 6320M1-C3 (100×215×47mm) 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
