What is the equivalent of a 1306EKTN9-C3 bearing?

The 1306EKTN9-C3 is a 30×74×18mm self-aligning ball bearing with verified equivalents across multiple brands: NSK 1306 C3, NTN 1306 C3, SKF 1306 ETN9 C3, Timken 1306 C3. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 1306EKTN9-C3 bearing?

The 1306EKTN9-C3 bearing has a bore diameter of 30mm, outer diameter of 74mm, and width of 18mm. It has a dynamic load rating of 19.5 kN, static load rating of 8.5 kN, and weighs 266g. Maximum speed with grease lubrication is 8,075 rpm.

Can I replace a FAG 1306EKTN9-C3 with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 1306EKTN9-C3 (30×74×18mm) 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.
