7006 ACE/HCP4AL1DGA Bearing Product Overview & Core Advantages
The 7006 ACE/HCP4AL1DGA is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and performance. Featuring a universal matchable (SU) design, this bearing can be paired in various configurations to handle combined radial and axial loads simultaneously. Its construction with ceramic balls and a phenolic cage enables superior high-speed capabilities and reduced rotational mass. Manufactured to P4A super precision tolerance with an extra light preload (Class A), it delivers outstanding running accuracy, rigidity, and rotational stability for the most critical machinery.

7006 ACE/HCP4AL1DGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The 25° contact angle and precision-ground raceways are optimized to support significant combined loads, providing high axial and radial stiffness.
- Superior High-Speed Performance: The combination of lightweight ceramic balls and a phenolic resin cage significantly reduces centrifugal forces, enabling a very high limiting speed of 71,500 rpm. This design minimizes friction and heat generation.
- Precision & Stability: Manufactured to P4A tolerance with an extra light preload, this bearing ensures minimal runout and vibration, which is critical for maintaining accuracy in high-speed spindles.
- Universal Matchability (SU): Bearings are supplied as a matched set of 2 and can be arranged in back-to-back (DB), face-to-face (DF), or tandem (DT) configurations to precisely meet application requirements for stiffness and load capacity.
7006 ACE/HCP4AL1DGA Bearing Typical Application Areas
This bearing is ideally suited for high-performance machinery where precision, speed, and reliability are paramount. Key applications include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Robotics: Arm joints and high-accuracy rotary axes.
- Aerospace & Defense Systems: Gyroscopes, radar systems, and auxiliary power units.
- High-Frequency Motors and Spindles: PCB drilling spindles and dental handpieces.
