What is the equivalent of a 1306 bearing?

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

What are the dimensions of a 1306 bearing?

The 1306 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 SKF 1306 with a FAG equivalent?

Yes. SKF and FAG bearings with the same ISO designation are dimensionally interchangeable. The 1306 (30×74×18mm) can be replaced with the equivalent FAG part number as long as the seal type (open) and clearance class (CN) match. Always verify load ratings and speed limits for your specific application.
