71916 CE/HCP4A Bearing Product Overview & Core Advantages
The 71916 CE/HCP4A is a high-precision, single-row Angular Contact Ball Bearing engineered for demanding applications requiring exceptional accuracy and speed. Its defining feature is the ability to support combined loads, simultaneously handling significant radial forces and thrust loads in one direction. Manufactured to a P4 (ABEC-7) tolerance class, it guarantees ultra-precise running accuracy. The use of a Ceramic ball and Phenolic cage combination contributes to its superior high-speed performance, low heat generation, and extended service life, making it an ideal choice for high-reliability spindles and precision machinery.
Model Code Breakdown
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 71916 | Basic bearing series and size designation (80mm bore, 110mm OD, 16mm width). | Defines the core bearing dimensions. |
| CE | Designates a 15° contact angle and high-precision design. | Optimized for high-speed operation and thrust capacity. |
| HC | Indicates Hybrid Ceramic construction (Ceramic balls, Steel rings). | Enables higher speeds, reduced weight, and longer life. |
| P4A | Specifies the P4 (ABEC-7) tolerance class and availability of preload. | Ensures ultra-precise running accuracy and system rigidity. |
71916 CE/HCP4A Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Design: The combination of steel rings and ceramic balls significantly reduces centrifugal forces, friction, and heat generation. This directly enables a higher limiting speed and provides electrical insulation properties.
- Phenolic Resin Cage: The lightweight and robust Phenolic cage is ideal for high-speed applications, offering excellent strength-to-weight ratio and smooth operation at extreme RPMs.
- 15° Contact Angle & Preload: The optimized contact angle provides an excellent balance between radial and axial load capacity. The availability of preload allows for precise adjustment of bearing internal clearance, resulting in superior system rigidity and minimal runout.
- Precision Engineering: Manufactured to P4 tolerance with tight dimensional control on the bore, outside diameter, and width, ensuring predictable performance and easy integration into high-precision assemblies.
