SD.32.C

Light series single row four-point contact ball slewing bearings are designed to accommodate operational speeds up to 2 meters per second (m/s) in circumferential velocity. This capability makes them suitable for applications where moderate rotational speeds are required, such as in machinery for indexing, positioning, and light-duty material handling. The bearings are engineered with optimized raceway profiles, ball sizes, and lubrication systems to ensure smooth operation and minimal frictional losses at these speeds. This allows them to effectively support axial and radial loads while maintaining stability and precision in their rotational movements. Overall, their ability to operate at up to 2 m/s makes light series single row four-point contact ball slewing bearings a reliable choice for applications that demand both speed and accuracy.
