Product Description
012.45.1400 is a single-row four-point-contact ball slewing bearing with an external gear. It features a 1400mm raceway center circle diameter. Its gothic-arch four-point-contact raceway enables the bearing to accommodate bidirectional axial loads, radial loads and tilting moments within a single bearing structure. This model is driven by a pinion meshing with the external teeth. The bearing measures 1260mm in bore diameter, 1540mm in outside diameter and 110mm in overall height. With stable rotation, comprehensive load capacity and easy maintenance, it is widely used in cranes, rotary platforms and heavy industrial equipment.
