7201 CD/P4A Bearing Product Overview & Core Advantages
The 7201 CD/P4A is a single-row angular contact ball bearing designed for high-precision applications requiring exceptional rotational accuracy and rigidity. Engineered to P4 (ABEC-7) tolerance class, this bearing is optimized to accommodate combined loads, primarily thrust loads in one direction, while offering superior high-speed performance. Its compact design, featuring a 12 mm bore and 32 mm outside diameter, makes it an ideal solution for space-constrained, high-reliability machinery where precision and high rigidity are paramount.
7201 CD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| CD | Optimized internal design with a 15° contact angle and specific internal clearances for high-precision applications. | Provides consistent performance under high-speed and high-load conditions. |
| P4 | Indicates P4 (ABEC-7) tolerance class. | Ensures extremely tight dimensional and running accuracy for superior rotational precision. |
| A | Indicates the bearing is supplied with a specific preload. | Enhances system rigidity, reduces vibration, and improves positional accuracy. |
7201 CD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single-row angular contact design, combined with a 15° contact angle and P4 precision, delivers high axial and radial stiffness, minimizing deflection under load for exceptional accuracy.
- Optimized Load Capacity: Engineered to efficiently handle combined loads, with a high dynamic load rating of 1316 lbf, making it suitable for applications with significant thrust and radial force components.
- Superior High-Speed Performance: The lightweight phenolic resin cage and optimized internal geometry contribute to a high limiting speed of 80,000 rpm, reducing centrifugal forces and maintaining stability.
- Pre-Lubricated for Immediate Use: The bearing is factory-lubricated, ensuring optimal performance from the start of operation within a wide temperature range of -30°C to 110°C.
