S71900 CD/P4A Bearing Product Overview & Core Advantages
The S71900 CD/P4A is a super-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high-speed performance. As a single-row bearing with a 15° contact angle, it is engineered to accommodate combined loads—handling significant radial loads alongside thrust loads in one direction. Its P4 (ABEC-7) tolerance class ensures minimal runout and vibration, making it ideal for high-reliability, high-precision spindles and machinery. The bearing comes pre-lubricated and is available with a preload, contributing to enhanced system rigidity and immediate operational readiness.
S71900 CD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| S7 | Indicates a series of super-precision, high-speed angular contact ball bearings. |
| 1900 | Specifies the bearing size series and bore diameter (10mm). |
| CD | Signifies a matched bearing arrangement with a specific preload level for high rigidity and precise shaft positioning. |
| P4A | Denotes the tolerance class P4 (ABEC-7), ensuring extremely tight dimensional and running accuracy. |
S71900 CD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single-row design with a 15° contact angle and the application of a preload (CD) work in concert to provide high axial and radial stiffness, minimizing deflection under load for superior machining accuracy.
- Superior High-Speed Capability: The lightweight phenolic resin cage reduces centrifugal forces, while the optimized internal geometry and high-grade chrome steel components allow for a high limiting speed of 80,000 rpm.
- Optimized Load Capacity: Engineered to support combined radial and axial loads simultaneously. The dynamic load rating of 565 lbf and static load rating of 248 lbf ensure reliable performance under demanding conditions.
- Ready-to-Install and Reliable: The bearing is factory pre-lubricated, ensuring optimal performance from startup and reducing maintenance requirements.
S71900 CD/P4A Bearing Typical Application Areas
This precision angular contact ball bearing is ideally suited for high-performance applications, including:
- High-Frequency Spindles for PCB drilling and milling
- Precision Machine Tool Spindles
- High-Speed Motors and encoders
- Medical and Dental Handpiece Drives
