Ball Bearing 72C/ACP4

72C/ACP4 standard angular contact ball bearings are the basic series of LKWE precision bearings based on ISO standards. The ring material is made of high-purity bearing steel (electroslag remelting), combined with special heat treatment technology, cold working technology and material modification technology, thanks to which the fatigue life of this series of bearings is greatly increased.

Structural Characteristics
  • Ceramic Ball: The Ball bearing 72C/ACP4 uses high-performance ceramic balls, which have high hardness, excellent wear resistance, and low weight. During high-speed operation, they have less wear and lower centrifugal force, enabling higher rotational speeds.
  • Angular Contact Structure: With an optimized angular contact design, the contact angle ranges from 15° to 25°. It has good axial and radial load-bearing capacities, can evenly distribute the load, avoid stress concentration, and ensure stable operation.
  • Precision Cage: Made of high-strength lightweight materials, it can precisely guide the balls, prevent collisions and friction, and maintain stable dimensions under high-speed and high-temperature conditions, ensuring smooth operation.
  • High-quality Rings: The rings are made of high-quality bearing steel, and through heat treatment and precision processing, they have good hardness, toughness, and dimensional stability. The surface roughness is extremely low, and they fit closely and smoothly with the ceramic balls, improving the rotational accuracy.
Performance Advantages
  • High Precision: Reaching the ACP4 precision level, it has extremely high dimensional and rotational accuracy. The tolerances are small, and the radial and axial runouts are minimal, providing stable support for precision equipment.
  • Excellent High-speed Performance: Thanks to the ceramic balls and optimized structure, it can operate stably at ultra-high rotational speeds. It runs smoothly during start-stop and speed change processes, suppresses vibration and noise, and resists fatigue.
  • Strong Adaptability: It can adapt to harsh environments such as high and low temperatures, dusty and humid conditions. With good wear resistance and a stable structure, it reduces maintenance costs and the risk of downtime.
Application
The bearings can be used in the following industries


  • High-end Machine Tools: Applied to the spindle systems of CNC machining centers and grinding machines to ensure machining accuracy and meet the requirements of the aerospace and automotive manufacturing industries.
  • Semiconductor Equipment: Suitable for lithography machines and etching machines, it drives and supports the precise movement of silicon wafers, improving the yield rate of chips.
  • Aerospace: It can be used in the auxiliary power systems of aircraft engines and the navigation and control systems of aircraft to ensure the stable operation of the equipment.
  • Precision Instruments: It provides precise support for the rotating components of optical measuring instruments and electron microscopes, ensuring measurement accuracy.
