Single Row Angular Contact Ball Bearings (General) 7308 BECBM

Single Row Angular Contact Ball Bearings (General) 7308 BECBM

The 7308 BECBM is a single-row angular contact ball bearing with a 40mm bore and 90mm outer diameter, crafted from sturdy chrome steel. It manages radial loads up to 11250 lbf and operates smoothly at speeds up to 12000 RPM.

With a 40° contact angle, it efficiently handles combined radial and axial loads. The brass cage enhances durability, while the open design simplifies lubrication and maintenance.

This bearing suits applications like pumps or gearboxes where precise angular contact is needed. It works in temperatures from -30°C to 110°C and meets P6 tolerance standards.

Weighing 0.68kg, it’s a robust yet manageable choice for industrial use. Compliant with RoHS and REACH, it’s interchangeable with SKF bearings for easy replacement.
