54308 Thrust Ball Bearing

The 54 series double direction thrust ball bearings with sphered housing washers (Model: 54308) are engineered to accommodate bidirectional axial loads while providing self-aligning capabilities. Comprising two shaft washers with spherical raceways, one center washer, and two sets of balls with cages, these bearings, in combination with the Sphered housing washer, can automatically compensate for angular misalignment (up to ±2°) in mounting surfaces, ensuring uniform load distribution. 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 40mm, outer diameter of 78mm, and height of 59mm, these bearings deliver a dynamic load capacity of 61.8kN and static load capacity of 122kN. Ideal for medium-precision equipment (e.g., machine tool feed systems, industrial robot joints), they are particularly suited for applications requiring bidirectional axial positioning, load support, and misalignment compensation. 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 30-80 N·m applied diagonally to housing washer bolts 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.
