What is the equivalent of a 6018-C3E bearing?

The 6018-C3E is a 90×140×24mm deep groove ball bearing with verified equivalents across multiple brands: NSK 6018 C3E, NTN 6018 C3, SKF 6018 C3, Timken 6018 C3. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 6018-C3E bearing?

The 6018-C3E bearing has a bore diameter of 90mm, outer diameter of 140mm, and width of 24mm. It has a dynamic load rating of 55.3 kN, static load rating of 46.5 kN, and weighs 1080g. Maximum speed with grease lubrication is 5,600 rpm.

Can I replace a FAG 6018-C3E with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 6018-C3E (90×140×24mm) 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
