Thrust Ball Bearing:51108

1.Precision Machine Tools and Processing Equipment

2.Automobiles and Transportation Equipment

Automobile Clutches and Transmissions:
Installed on the clutch shaft of a manual transmission, it withstands axial pressure when the clutch is engaged, enabling smooth gear shifting. In the oil pump shaft of an automatic transmission, it endures the axial load generated by high – speed rotation. Its pre – lubrication design can reduce maintenance frequency to adapt to a compact vehicle layout.
Commercial Vehicle Suspension Systems
Located at the articulation points of the truck’s balance shaft or suspension, it is used to absorb the axial impact caused by road bumps. The 52100 bearing steel material (HRC 58–62) can resist wear caused by long – term vibration, thereby improving ride comfort.

Vertical shafts of vertical pumps and compressors:
Used at the lower end of the impeller shafts of deep well pumps and vertical centrifugal pumps to support the unidirectional axial thrust generated by fluid pressure (such as water pressure reaction force), prevent shaft misalignment, and ensure the efficient operation of the pump. In screw compressors, it bears the axial load generated by the screw to maintain the seal of the compression chamber.

Rotors of generators and motors
Located at the shaft end of the rotors of small and medium-sized motors, it bears the axial force generated by magnetic pull. The detachable structure (separable inner and outer rings) can be quickly disassembled during motor maintenance, reducing downtime and costs.

3.Lifting and Construction Machinery

Winches and Lifting Equipment: Installation

At the end of the drum shaft of electric hoists and small cranes, it is used to bear the axial load generated by the tension of the wire rope. Its static load capacity is as high as 92,200N, and it can withstand sudden overloads, ensuring safe operation. Its compact size (outer diameter 68 mm × thickness 15 mm) is very suitable for lifting machinery with limited space.

Construction Machinery Jacking SystemIt is used at the shaft end of hydraulic jacks or cylinders of construction hoists. Through one-way load-bearing, it ensures stable control during the jacking process. The smooth surface design can minimize dust accumulation and is suitable for harsh outdoor conditions.

4.Automation and Light Industry Equipment 

Conveyor Belts and Material Handling Systems
At the shaft ends of conveyor rollers in the food and electronics industries, it can withstand the axial force generated by the conveyor belt tension, operate with low noise, and meet the requirements of clean workshops. The detachable design facilitates quick cleaning and complies with food – grade hygiene standards.

Precision Instruments and Testing Equipment:
In precision equipment such as rotary worktables and torque testers, it provides high – precision axial positioning to ensure reliable measurement data. The copper cage optimizes the movement trajectory of the balls, reducing frictional heat and its impact on the instrument’s accuracy.

Conclusion
The FODA thrust ball bearing 51108, with its professional one-way load design, wear-resistant material technology, and convenient installation/maintenance, has become an ideal axial support solution for machine tools, automotive systems, fluid machinery, and automated equipment. Whether it is to ensure machining accuracy or reliability in heavy-duty applications, this bearing, through structural optimization and material enhancement, balances performance stability and cost-effectiveness to meet the needs of various industries for axial load management.。
