Product description Technical parameter
Precision angular contact ball bearing, belongs to the deep groove ball bearing deformation structure, suitable for all kinds of precision machinery selection, this series of bearings can bear radial load and axial load at the same time, can work at a higher speed. The larger the contact angle, the higher the axial load carrying capacity. According to the axial load size, contact angle is mainly divided into C-15 degrees, AC-25 degrees, A-30 degrees, B-40 degrees type structure, small friction coefficient, high limit speed, high manufacturing accuracy, can provide high-speed ceramic ball series bearings and sealed series bearings, cage mainly organic processing window brass cage, steel plate stamping cage, glass fiber reinforced nylon cage (nylon), and phenolic Laminated cloth tube cage (rubber wood), also can provide universal pair and any pair combination bearings. Mainly used in: machine tool spindles, high frequency motors, gas turbines, centrifugal separators, small car front wheels, differential pinion shafts, booster pumps, drilling platforms, food machinery, indexing heads, welding machines, low-noise cooling towers, electromechanical equipment, coating equipment, machine tool groove plates, arc welding machines, water pumps, modules, and support seats.

In what ways do precision Angular contact ball bearings for precision machinery contribute to improved machine tool accuracy?
Precision Angular Contact Ball Bearings play a crucial role in improving machine tool accuracy in several ways. 
Reduced Runout: Precision Angular Contact Ball Bearings are designed to minimize radial and axial runout. This reduction in runout contributes to enhanced accuracy in machining operations, ensuring that the tool or workpiece moves along a more precise path.
High Axial Rigidity: The design of these bearings provides high axial rigidity, preventing excessive deflection and minimizing errors in the tool's positioning. This is particularly important in applications where cutting forces and tool engagement vary.
Optimized Contact Angle: The specific contact angle of precision Angular Contact Ball Bearings allows for the effective distribution of both radial and axial loads. This optimization ensures that forces are evenly distributed, minimizing deformations and inaccuracies in machining.
Preloaded Bearings: Preloading, a controlled axial displacement of the bearing components, helps eliminate clearance in the bearing system. This eliminates any play in the bearings, reducing backlash and contributing to improved precision in machine tool movements.
High-Speed Capability: Precision Angular Contact Ball Bearings are designed to operate at high speeds while maintaining accuracy. This is critical in machine tools where rapid movements are required without sacrificing precision.
Low Friction: These bearings are engineered for low friction and high efficiency, reducing heat generation during operation. Low friction contributes to more predictable and stable machine tool behavior, improving accuracy over extended periods of use.
Consistent Performance: The precision manufacturing processes involved in producing these bearings ensure uniformity and consistency in performance. This uniformity is crucial for maintaining accuracy in repetitive machining tasks.
Minimal Heat Generation: The efficient design of precision Angular Contact Ball Bearings minimizes heat generation during operation. This is essential in maintaining dimensional stability and preventing thermal expansion, which can impact machining accuracy.
Enhanced Stiffness: The combination of materials and design features in precision bearings results in increased stiffness. This stiffness contributes to the overall stability of the machine tool, preventing unwanted vibrations and ensuring accurate tool positioning.
Sealing Technology: Precision Angular Contact Ball Bearings often incorporate advanced sealing technologies to protect against contaminants. This extends bearing life and ensures that the accuracy of the machine tool is maintained over time.
precision Angular Contact Ball Bearings contribute to improved machine tool accuracy by minimizing runout, providing high axial rigidity, optimizing contact angles, preloading for reduced clearance, enabling high-speed capabilities, reducing friction, ensuring consistent performance, controlling heat generation, enhancing stiffness, and incorporating effective sealing technologies. These factors collectively contribute to achieving and maintaining the high level of precision required in modern machining processes.
