S71916 CE/P4A Bearing Product Overview & Core Advantages
The S71916 CE/P4A is a precision single-row angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high-speed performance. Manufactured to P4 (ABEC-7) tolerance class, it offers superior dimensional stability and running accuracy. Its key advantage lies in its ability to accommodate combined loads—simultaneously handling significant radial loads and axial loads in one direction—thanks to its defined 15° contact angle. This makes it an ideal, compact solution for high-rigidity, high-reliability spindle arrangements.
S71916 CE/P4A Bearing Model Code Explained, Specifications & Naming Convention
The model number S71916 CE/P4A provides detailed technical specifications:
- S: Identifies the bearing as part of a super-precision series.
- 7: Denotes the angular contact bearing type.
- 1916: Specifies the size series; 19 for the medium series and 16 for an 80mm bore.
- CE: Indicates a contact angle of 15° and specific internal design optimizations for high-speed operation.
- P4A: Defines the tolerance class. P4 is equivalent to ABEC-7, offering very high precision, and the A suffix indicates specific tolerance deviations for universal matching.
S71916 CE/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single-row design, manufactured to P4 tolerance class with a phenolic resin cage, ensures minimal vibration and high running accuracy, which is critical for high-speed applications.
- Superior Load Capacity: Engineered with a 15° contact angle and high-grade chrome steel components, this bearing effectively supports combined radial and axial loads (Dynamic Load Rating: 5152 lbf / Static Load Rating: 4050 lbf).
- Optimized High-Speed Performance: The lightweight phenolic cage and optimized internal geometry contribute to a high limiting speed of 16,500 rpm, reducing centrifugal forces and operational temperatures.
- Pre-Lubricated and Sealed: The bearing comes lubricated and sealed, protecting against contamination and providing long-term, maintenance-free operation within a temperature range of -30°C to 110°C.
S71916 CE/P4A Bearing Typical Application Areas
This precision angular contact ball bearing is ideally suited for high-performance machinery requiring high rotational speeds and accuracy, including:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- Industrial Pumps and Compressors
- Advanced Robotics and Aerospace Components
