S7014 CB/HCP4A Bearing Product Overview & Core Advantages
The S7014 CB/HCP4A is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional speed, rigidity, and accuracy. Its single-row design with a 15° contact angle is optimized to handle combined radial and axial loads simultaneously. Manufactured to a P4 (ABEC-7) tolerance class, it guarantees superior running accuracy. The use of ceramic balls and a phenolic cage significantly enhances its high-speed performance and reduces rotational mass, making it an ideal choice for high-reliability, high-RPM machinery.
Model Code Breakdown
The model number S7014 CB/HCP4A provides detailed technical specifications:
- S: Denotes a bearing with a high-precision design.
- 7014: Standard size designation (Bore: 70mm, OD: 110mm, Width: 20mm).
- CB: Indicates a specific preload class (Universal/Moderate preload).
- HC: Stands for Hybrid Ceramic, signifying the use of ceramic balls with steel rings.
- P4A: Specifies the tolerance class P4 (ABEC-7) with specific accuracy and running requirements.
S7014 CB/HCP4A Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The P4 tolerance and CB preload ensure minimal deflection and precise shaft positioning, providing excellent system stability and rigidity.
- Superior High-Speed Capability: The combination of ceramic balls (lower density, reduced centrifugal force) and a lightweight phenolic resin cage allows for a very high limiting speed of 19,000 rpm.
- Enhanced Load Capacity: The 15° contact angle is optimally designed to support significant combined loads, with a dynamic load rating of 4275 lbf and a static load rating of 3668 lbf.
- Temperature & Longevity: The hybrid construction offers reduced heat generation and can operate within a temperature range of -30°C to 110°C. The bearing is pre-lubricated for immediate use and long service life.
