Product Description

111.25.500 is a single-row crossed roller slewing bearing with external gear. It features 25mm diameter rollers and 500mm raceway center circle diameter. The crossed roller design provides higher rigidity and moment load capacity compared to ball bearings. This model is driven by a pinion meshing with the external teeth. It measures 398mm inner diameter, 602mm outer diameter, and 75mm height. With stable rotation, high load capacity, and easy maintenance, it is widely used in cranes, rotary platforms, and heavy industrial equipment.
