71802 ACD/P4 Bearing Product Overview & Core Advantages
The 71802 ACD/P4 is a single-row angular contact ball bearing engineered for applications demanding high precision and superior performance. As a metric-series bearing, it is designed to accommodate high combined loads (radial and axial) simultaneously, with its 25° contact angle optimizing axial load capacity. Manufactured to the exacting P4 (ABEC-7) tolerance class, it ensures exceptional running accuracy and rotational stability. Its compact design, featuring a 15 mm bore and 5 mm width, makes it ideal for space-constrained, high-speed applications such as precision spindles.
71802 ACD/P4 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACD | Indicates a 25° contact angle and optimized internal geometry for high axial load capacity and rigidity. |
| P4 | Denotes the high precision tolerance class (equivalent to ABEC-7), ensuring minimal runout and vibration for ultra-smooth operation. |
71802 ACD/P4 Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: The P4 tolerance class and phenolic resin cage contribute to exceptional dimensional stability and low vibration, enabling high rotational accuracy and system rigidity.
- Optimized Load Capacity: The 25° contact angle is specifically designed to handle significant combined loads, providing robust performance where radial and axial forces are present.
- High-Speed Capability: The lightweight phenolic cage, combined with factory-applied lubrication, allows for a high limiting speed of 80,000 rpm, making it suitable for demanding spindle applications.
- Superior Material Construction: Manufactured from chrome steel for both rings and balls, the bearing offers high hardness, wear resistance, and long service life.
