What is the equivalent of a 70191 bearing?

The 70191 is a 65×100×18mm angular contact ball bearing with verified equivalents across multiple brands: NSK 6013 C3E, NTN 6013 C3, SKF 6013 C3, Timken 6013 C3. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 70191 bearing?

The 70191 bearing has a bore diameter of 65mm, outer diameter of 100mm, and width of 18mm. It has a dynamic load rating of 31.9 kN, static load rating of 25 kN, and weighs 426g. Maximum speed with grease lubrication is 8,000 rpm.

Can I replace a FAG 70191 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 70191 (65×100×18mm) 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.
