S71916 CB/HCP4A Bearing Product Overview & Core Advantages
The S71916 CB/HCP4A is a high-precision angular contact ball bearing engineered for applications demanding exceptional accuracy and reliability. This single-row bearing is designed to accommodate combined loads, efficiently handling both radial and substantial axial loads in one direction. Its defining characteristics include a P4 (ABEC-7) tolerance class, a 15° contact angle, and a ceramic ball and phenolic cage construction, making it an ideal solution for high-speed and high-rigidity operational environments.
Model Code Breakdown
The model number S71916 CB/HCP4A provides detailed technical specifications through its suffixes:
- S: Denotes a bearing from a specific high-performance series.
- 7: Indicates an angular contact ball bearing.
- 1916: Specifies the dimensional series; 19 for the width series and 16 for the bore diameter code (80 mm).
- CB: Signifies a specific internal clearance and preload condition, optimized for operational stability.
- HC: Stands for Hybrid Ceramic, indicating the use of ceramic balls with steel rings.
- P4A: Denotes a P4 (ABEC-7) tolerance class, ensuring extremely tight dimensional and running accuracy.
S71916 CB/HCP4A Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic balls significantly reduces friction, heat generation, and wear. This construction enables higher limiting speeds, extended service life, and improved performance in electrically sensitive or high-temperature environments.
- Phenolic Resin Cage: The lightweight and robust phenolic cage ensures excellent guidance of the ceramic balls at high speeds, contributing to smooth operation and low vibration levels.
- High Precision & Rigidity: Manufactured to a P4 tolerance class and featuring a 15° contact angle with preload, this bearing provides superior rotational accuracy, system stiffness, and precise shaft positioning.
- Optimized Load Capacity: The design is capable of handling significant combined loads (radial and axial), with a dynamic load rating of 3510 lbf and a static load rating of 3375 lbf.
- Sealed & Lubricated for Life: As a sealed and pre-lubricated unit, the bearing is protected from contamination and is maintenance-free within its specified temperature range of -30° to 110 °C.
S71916 CB/HCP4A Bearing Typical Application Areas
