Product Description
The 52 series double direction thrust ball bearings (Model: 52313) are specifically designed to accommodate axial loads in both directions. Comprising two shaft washers, one center washer, and two sets of balls with cages, these bearings provide bidirectional axial load capacity while maintaining high axial stiffness. Featuring a 90° contact angle, they ensure uniform load distribution across the balls. Manufactured from chrome steel (GCr15) with quenching and tempering treatment, the bearing surfaces achieve a hardness of HRC60-64, offering excellent wear resistance and fatigue strength. With a bore diameter of 65mm, outer diameter of 115mm, and height of 64mm, these bearings deliver a dynamic load capacity of 106kN and static load capacity of 240kN. Ideal for general industrial equipment (e.g., pumps, gearboxes, electric motors), they are particularly suited for applications requiring bidirectional axial positioning and load support. Compliant with ISO 9001 standards, these bearings support grease lubrication (oil lubrication available for high-speed applications) and operate within a temperature range of -30°C to +120°C. Proper installation requires precise alignment of the center washer, and a recommended torque of 40-100 N·m is advised for bolt tightening to ensure optimal performance and service life. The manufacturer offers a Standard 12-month warranty extendable up to 18 months through authorized Jinyu distributors. OEM solutions available.
