Ball Bearing 70C/ACP4

Structural Characteristics

• High-quality Ceramic Rolling Elements: The Ball bearing 70C/ACP4 uses ceramic balls. This material has exceptional hardness and light weight. At extremely high rotational speeds, it generates small centrifugal force and inertial force, greatly reducing wear and extending the service life of the bearing. Meanwhile, its low coefficient of thermal expansion enables it to maintain precise dimensions during temperature fluctuations, ensuring operational accuracy.
• Precise Guidance Cage: It is equipped with a carefully designed cage, often made of high-strength engineering plastics or lightweight alloys. It can accurately control the movement trajectory of the ceramic balls, preventing collisions between the balls and maintaining smooth operation. Moreover, when the bearing runs at high speeds and the temperature rises, the cage is not prone to deformation, safeguarding the dynamic performance of the bearing.
• Ultra-precision Ring Process: The rings are made of high-quality bearing steel and go through a series of complex processes such as forging, heat treatment, and ultra-precision grinding. The surface roughness is controlled at an extremely low level, ensuring smooth contact with the ceramic balls and minimizing friction loss. This endows the bearing with excellent rotational accuracy, meeting the requirements of high-end precision applications.

Performance Advantages

• Ultra-high Precision Assurance: Reaching the P4 precision grade, it demonstrates excellent dimensional accuracy and rotational accuracy. The dimensional tolerances are strictly limited. For key dimensions such as the inner diameter, outer diameter, and width, the deviations are minimal. During rotation, the radial runout and axial play are almost zero, providing a solid foundation of precision for precision machining, precision measuring instruments, etc.
• Ultimate High-speed Performance: With the ceramic rolling elements and a sophisticated structural design, it performs remarkably well in the field of extremely high rotational speeds. In the face of frequent high-speed start-stop, rapid acceleration, and deceleration, it can still operate stably, suppressing vibration and noise to the lowest level and minimizing fatigue damage caused by high-speed operation. It is suitable for the needs of cutting-edge fields such as aerospace and high-end equipment manufacturing.
• Excellent Environmental Adaptability: Whether in a hot and high-temperature industrial environment or in harsh working conditions with humidity, dust, and even a certain risk of chemical corrosion, this bearing can, with its stable structure and reliable material properties (even better if there is a sealing design), tenaciously resist adverse external factors, operate stably and reliably, and effectively reduce the maintenance costs of equipment and the risk of downtime.
