7200 ACD/HCP4A Bearing Product Overview & Core Advantages
The 7200 ACD/HCP4A is a single-row angular contact ball bearing engineered for applications demanding high precision and high-speed operation. Its defining feature is the 25° contact angle, optimized to support significant combined loads (radial and axial loads simultaneously). Manufactured to P4 (ABEC-7) tolerance class, it ensures exceptional running accuracy. The use of a phenolic cage and ceramic balls contributes to lower friction, higher limiting speeds, and superior performance in demanding conditions.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 7200 | Basic series designation, indicating a light series angular contact bearing with a 10mm bore. |
| ACD | Signifies a 25° contact angle, optimized for high axial load capacity and rigidity. |
| HCP4A | Indicates a P4 (ABEC-7) tolerance class and is supplied with a specific preload for immediate high-rigidity performance. |
7200 ACD/HCP4A Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of a lightweight phenolic cage and low-density ceramic balls reduces centrifugal forces, enabling a high limiting speed of 95,000 rpm.
- Superior Rigidity & Load Capacity: The 25° contact angle provides excellent resistance to combined loads, making the bearing exceptionally rigid under complex loading conditions.
- Precision Performance: Manufactured to P4 tolerance with a preload, this bearing offers minimal runout and precise shaft positioning, critical for high-accuracy applications.
- Optimized for Demanding Environments: Ceramic balls offer advantages including electrical insulation, reduced thermal expansion, and extended service life, especially in high-speed or corrosive environments.
