52313 Bearing Product Overview & Core Advantages
The 52313 metric thrust ball bearing is engineered for high-precision axial load applications requiring exceptional rigidity and reliability. This thrust ball bearing features an open design without seals, optimized for maximum axial dynamic load capacity of 23,850 lbf and axial static load rating of 54,000 lbf. Manufactured from chrome steel components with a stainless steel cage, it delivers superior performance in demanding industrial environments. Its precision-ground raceways and controlled tolerances ensure smooth operation under pure thrust loads, making it ideal for applications where axial stiffness and positional accuracy are critical.

52313 Bearing Structural Features & Performance Benefits
High Load Capacity Design: The bearing's optimized raceway geometry and chrome steel construction enable it to handle substantial pure thrust loads with minimal deformation. The stainless steel cage provides excellent guidance and stability at operating temperatures up to 110°C.
Precision Engineering: With tight dimensional tolerances (bore: -0.015mm to 0, OD: -0.02mm to 0) and controlled chamfer dimensions (housing washer: 1.1mm, shaft washer: 0.6mm), the bearing ensures precise axial positioning and smooth operation.
High-Speed Capability: The open design and optimized cage configuration allow for limiting speeds up to 2,200 rpm, making it suitable for applications requiring rapid axial movement.
Material Excellence: All chrome steel components provide superior hardness and wear resistance, while the stainless steel cage offers corrosion resistance and dimensional stability across the operating temperature range (-30° to 110°C).
