71802 CD/P4 Bearing Product Overview & Core Advantages
The 71802 CD/P4 is a single-row angular contact ball bearing designed for applications demanding high precision and superior rotational accuracy. Engineered to P4 (ABEC-7) tolerance class, it excels in handling combined radial and axial loads simultaneously. Its compact design, with a minimal cross-section, makes it ideal for space-constrained, high-speed machinery requiring exceptional rigidity and reliable performance. The bearing comes pre-lubricated and is manufactured from high-grade chrome steel for durability.
71802 CD/P4 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 71802 | Basic bearing designation | Defines the standard bearing dimensions: 15mm bore, 24mm OD, 5mm width. |
| C | 15° Contact angle | Optimized for high axial load capacity and high-speed operation. |
| D | Preload class | Indicates a light preload is applied, enhancing rigidity and minimizing axial/radial play for precise shaft positioning. |
| P4 | Tolerance class (ABEC-7) | Signifies ultra-precise manufacturing tolerances for applications requiring minimal runout and vibration, such as high-speed spindles. |
71802 CD/P4 Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single-row angular contact design, combined with the P4 precision rating and preload, ensures maximum system stiffness and exceptional running accuracy, critical for minimizing deflection under load.
- Optimized Load Capacity: The 15° contact angle is engineered to efficiently support significant combined loads, including radial loads and axial loads in one direction.
- High-Speed Capability: The lightweight phenolic cage provides excellent strength-to-weight ratio, reducing centrifugal forces and enabling stable operation at the high limiting speed of 90,000 rpm. The open design facilitates efficient lubrication and cooling.
- Durability and Reliability: Components made from high-carbon chrome steel offer high hardness and wear resistance. The bearing is pre-lubricated for immediate use and reliable operation within its specified temperature range.
