SKF announced the UC 300 ball bearing units, which the company reported feature superior sealing and stronger locking, and are interchangeable with all Japanese-Industrial- Standards-compliant housings. The UC 300 is ideal for use in highly contaminated industrial environments, the company reported. Designed for applications with higher peak loads and lower rotation speeds, each unit features a grub screw locking system set at an angle of 62°, which gives optimal holding power. The units are available with bores ranging up to 100 mm. Typical applications include conveyors, belt-pulley and chain transmissions, and cranes.
