51314 Bearing Product Overview & Core Advantages
The 51314 metric thrust ball bearing is engineered for applications requiring high-precision axial load handling. Designed exclusively for thrust load direction, this bearing delivers exceptional performance in demanding environments. Its open seal type allows for optimal lubrication access while maintaining structural integrity. Manufactured from 52100 Chrome Steel rings and balls with a Stainless Steel cage, it offers superior corrosion resistance and durability. The bearing's precise dimensional tolerances ensure reliable operation in high-speed applications up to 2,600 rpm, making it ideal for machinery requiring exact axial positioning and load capacity.

51314 Bearing Structural Features & Performance Benefits
High Load Capacity Design: The 51314 bearing features optimized raceway geometry and precision-grade balls that deliver exceptional axial dynamic load rating of 30,375 lbf and axial static load rating of 72,000 lbf. This robust construction ensures reliable performance under heavy thrust loads.
Precision Engineering: With tight dimensional tolerances (bore diameter: -0.015mm to 0, outside diameter: -0.025mm to 0), this bearing maintains exact alignment and minimal runout, critical for precision applications requiring accurate axial positioning.
High-Speed Capability: The stainless steel cage provides excellent guidance and stability, enabling operation at limiting speeds up to 2,600 rpm. The open design facilitates efficient lubrication circulation for heat management during high-speed operation.
Material Excellence: Constructed from 52100 Chrome Steel for both rings and balls, the bearing offers superior hardness and wear resistance. The stainless steel cage adds corrosion resistance and maintains structural integrity across the operating temperature range of -30° to 110°C.
