Details

SL-type cylindrical roller bearings are double-row full-compliment cylindrical roller bearings that have a thin cross-section and can withstand extremely large radial and impact loads. The "SL" designation typically implies a design that optimizes the number of rollers within the bearing, enhancing load-bearing capabilities. The thin cross-section design allows for efficient space utilization while ensuring the bearing's ability to handle substantial radial loads. These bearings are suitable for a wide range of slow to moderate-speed, heavily loaded applications such as construction machinery, vehicles, steel machinery, and lifting machinery.
