The 51124 SKF manufactured by SKF is a thrust single direction ball bearing with an inner diameter of 120mm and an outer diameter of 155mm. The ball bearing is designed to transmit axial loads in one direction and has high axial stiffness and support capability. The bearing is designed with cylindrical or tapered raceways, depending on the load and direction, allowing it to accommodate both radial and axial loads. The bearing is self-aligning, resistant to shock loads, has a low frictional torque, and is beneficial in mounting systems with a need to accommodate misalignment.
