Structural Features and Performance Benefits
High Load Capacity Design: The 51110 bearing is specifically engineered for heavy axial loads, featuring optimized raceway geometry that distributes stress evenly across contact surfaces. This design achieves an impressive axial static load rating of 16,875 lbf while maintaining structural integrity.
Precision Engineering: With tight dimensional tolerances (bore tolerance: -0.012mm to 0 and width tolerance: +0.02mm to -0.25mm), this bearing ensures precise shaft alignment and minimal runout. The 0.6mm chamfer dimension facilitates easier installation and prevents stress concentration.
High-Speed Capability: The stainless steel cage and precision-ground components enable operation at limiting speeds up to 6,300 rpm, making it suitable for high-rotation applications. The open design allows for efficient lubrication management in high-speed environments.
Material Excellence: Constructed from 52100 Chrome Steel for both rings and balls, the bearing delivers exceptional hardness and wear resistance. This material selection ensures long service life even under continuous axial dynamic loads.
51110 Bearing Typical Application Areas
- Industrial Machinery: Vertical pumps, gearboxes, and machine tool spindles requiring precise axial positioning
- Automotive Systems: Clutch release mechanisms and steering column assemblies
- Power Transmission: Thrust load applications in speed reducers and vertical shaft arrangements
- Material Handling: Crane hooks, lifting equipment, and vertical conveyor systems
