Thrust Ball Bearing:51108

1. Precision Machine Tools and Processing Equipment

Axial Positioning for Machine Tool Spindles
Used at the end of main shafts in machine tools such as lathes and grinders, it withstands unidirectional axial forces from tool feeding during cutting (e.g., axial components of radial cutting forces). The precision-ground inner bore (40mm ID) ensures an interference fit with the spindle, maintaining positioning accuracy at high speeds and reducing vibration impacts on machining surfaces.

Axial Limiting in Gearboxes
In reducers or gearboxes, it restricts axial displacement from helical or bevel gear meshing, preventing gear misalignment and wear, and enhancing transmission system stability and lifespan.

2. Automotive and Transportation Equipment

Automotive Clutches and Transmissions
Installed on the clutch shaft of manual transmissions, it withstands axial pressure during clutch engagement for smooth gear shifting. In automatic transmission oil pump shafts, it supports axial loads from high-speed rotation, with a pre-lubricated design reducing maintenance frequency to suit compact vehicle layouts.

Commercial Vehicle Suspension Systems
At the articulation points of truck balance shafts or suspensions, it absorbs axial impacts from road bumps. The 52100 bearing steel material (HRC 58–62) resists long-term vibration-induced wear, improving ride smoothness.

3. Fluid Machinery and Power Equipment

Vertical Shafts in Vertical Pumps and Compressors
Used at the lower end of impeller shafts in deep-well pumps and vertical centrifugal pumps, it supports unidirectional axial thrust from fluid pressure (e.g., water pressure reaction forces), preventing shaft misalignment and ensuring efficient pump operation. In screw compressors, it withstands axial loads from screws to maintain compression chamber sealing.

Generator and Motor Rotors
At the shaft ends of small and medium-sized motor rotors, it bears axial forces from magnetic pull. The detachable structure (separable inner/outer rings) enables quick disassembly during motor maintenance, reducing downtime and costs.

4. Lifting and Construction Machinery

Winches and Hoisting Equipment
At the drum shaft ends of electric hoists and small cranes, it supports axial loads from wire rope tension. With a 92,200N static load capacity, it handles sudden overloads to ensure operational safety. Its compact dimensions (68mm OD × 15mm thickness) fit space-constrained lifting machinery.

Jacking Systems in Construction Machinery
Used at the shaft ends of hydraulic jacks or construction elevator cylinders, it ensures stable control during jacking through unidirectional load bearing. The smooth surface design minimizes dust accumulation, suitable for outdoor harsh conditions.

5. Automation and Light Industrial Equipment

Conveyor Belts and Material Handling Systems
At the shaft ends of conveyor rollers in food and electronics industries, it withstands axial forces from belt tension, with low-noise operation meeting clean workshop requirements. The detachable design facilitates quick cleaning, complying with food-grade hygiene standards.

Precision Instruments and Testing Equipment
In rotating worktables, torque testers, and other precision devices, it provides high-precision axial positioning to ensure reliable measurement data. The copper cage optimizes ball movement trajectories, reducing friction heat and its impact on instrument accuracy.
