71916 CD/HCP4A Bearing Product Overview & Core Advantages
The 71916 CD/HCP4A is a single-row angular contact ball bearing engineered for high-precision and high-speed applications. Its design is optimized to support significant combined loads (radial and axial loads in one direction) with exceptional accuracy and rigidity. Key advantages include its P4 (ABEC-7) tolerance class for superior running accuracy, a phenolic resin cage enabling high rotational speeds, and ceramic balls that reduce weight and centrifugal force for enhanced performance. This bearing is preloaded and pre-lubricated, making it ready for demanding installations requiring high reliability and minimal maintenance.
71916 CD/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 71916 | Standard bearing series number, defining the basic dimensions: 80mm bore, 110mm outside diameter, 16mm width. |
| C | Designates a 15° contact angle, optimized for high-speed operation and moderate axial load capacity. |
| D | Indicates the bearing is manufactured with a high-precision tolerance class. |
| HC | Signifies the use of Hybrid Ceramic components, specifically ceramic balls. |
| P4 | Confirms the P4 tolerance class (equivalent to ABEC-7), ensuring extremely tight dimensional and running accuracy. |
| A | Denotes that the bearing is supplied with a specific preload for immediate high-rigidity performance. |
71916 CD/HCP4A Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The use of ceramic balls with a steel ring significantly reduces rotating mass, lowering centrifugal forces and operating temperatures. This directly contributes to a higher limiting speed (22,000 rpm) and extended service life, especially in high-speed applications.
- Phenolic Resin Cage: The lightweight and robust phenolic cage offers excellent dimensional stability and low friction at high speeds, further supporting the bearing's high-speed performance.
- High Rigidity & Load Capacity: The 15° contact angle and preload provide high axial and radial rigidity, enabling the bearing to handle significant combined loads with minimal deflection. With a dynamic load rating of 8190 lbf and a static load rating of 8775 lbf, it offers reliable performance under demanding conditions.
- Precision Engineering: Manufactured to P4 (ABEC-7) tolerance, this bearing ensures smooth, quiet, and vibration-free operation, which is critical for the accuracy of the overall system.
71916 CD/HCP4A Bearing Typical Application Areas
This high-performance angular contact ball bearing is ideally suited for advanced machinery requiring precision and speed, including:
- High-Speed Machine Tool Spindles (e.g., CNC milling and grinding machines)
- Precision Robotics and automated handling systems
- High-Frequency Motors and spindle drives
- Aerospace & Defense instrumentation and control systems
- Medical Equipment such as high-speed dental handpieces and centrifuges
