7013 ACB/HCP4A Bearing Product Overview & Core Advantages
The 7013 ACB/HCP4A is a high-precision single row angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and performance. Its defining feature is the 25° contact angle and availability with preload, enabling it to efficiently handle combined loads (radial and axial loads simultaneously). Manufactured to a P4 (ABEC-7) tolerance class, this bearing offers superior running accuracy, high rigidity, and reliable operation at high speeds, making it an ideal choice for high-performance spindles and precision machinery.
7013 ACB/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7013 | Standard bearing series designation, indicating a metric single row angular contact bearing with a 65mm bore, 100mm OD, and 18mm width. |
| ACB | Signifies a specific internal design and contact angle of 25°. |
| HCP4A | Indicates the bearing is supplied with a preload and manufactured to a P4 (ABEC-7) tolerance class for superior precision. |
7013 ACB/HCP4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The 25° contact angle and preload ensure minimal axial and radial deflection under load, providing exceptional stiffness and running accuracy critical for machine tool spindles.
- High-Speed Capability: The lightweight phenolic resin cage and ceramic balls reduce centrifugal forces, lower operating temperatures, and enable a high limiting speed of 30,000 rpm.
- Superior Load Capacity: Designed to support significant combined loads, with a dynamic load rating of 3285 lbf and a static load rating of 2745 lbf.
- Advanced Material Combination: The use of ceramic balls with chrome steel rings offers benefits such as reduced weight, electrical insulation, and extended service life due to superior hardness and wear resistance.
7013 ACB/HCP4A Bearing Typical Application Areas
This precision angular contact bearing is ideally suited for high-performance applications including:
- Machine Tool Spindles (High-speed milling, grinding)
- Precision Grinding Spindles
- High-Frequency Motors
- Robotic Arm Joints
- Aerospace Control Systems
