7022 ACB/HCP4A Bearing Product Overview & Core Advantages
The 7022 ACB/HCP4A is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional rotational accuracy and rigidity. Designed as a single bearing with a 25° contact angle and preload, it delivers superior performance in managing combined radial and axial loads simultaneously. Its construction with a phenolic cage and ceramic balls enables high-speed operation, while the P4 (ABEC-7) tolerance class ensures consistent, reliable performance in precision machinery.
7022 ACB/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| 7022 | Basic bearing series designation, indicating a metric 110mm bore, 170mm OD, and 28mm width. |
| ACB | Angular Contact Bearing with a specific contact angle and internal design. |
| HCP4A | Indicates a P4 (ABEC-7) tolerance class and likely a specific preload level (A) for high precision and rigidity. |
7022 ACB/HCP4A Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The 25° contact angle and application of preload significantly increase system stiffness, minimizing deflection under load for superior positional accuracy.
- High-Speed Capability: The combination of a lightweight phenolic resin cage and low-density ceramic balls reduces centrifugal forces, enabling a high limiting speed of 16,000 rpm.
- Superior Load Capacity: Engineered to handle significant combined radial and axial loads, with a dynamic load rating of 7898 lbf and static load rating of 7650 lbf.
- Extended Service Life: Ceramic balls offer superior wear resistance, lower friction, and operational stability across a wide temperature range from -30°C to 110°C.
7022 ACB/HCP4A Bearing Typical Application Areas
This bearing is ideally suited for high-performance applications, including:
- Machine Tool Spindles (High-speed machining centers, grinding spindles)
- Precision Robotics (Articulated arms, high-accuracy joints)
- Aerospace & Defense Systems (Gyroscopes, radar systems, avionics)
- High-Frequency Motors and Spindles
