S71914 CB/P4A Bearing Product Overview & Core Advantages
The S71914 CB/P4A is a single-row angular contact ball bearing engineered for high-precision applications requiring exceptional rotational accuracy and rigidity. Designed to accommodate primarily axial loads in one direction and combined loads, it features a 15° contact angle for optimal performance. Manufactured to P4 (ABEC-7) tolerance class, this bearing delivers superior running accuracy and is preloaded for enhanced system stiffness and reduced vibration, making it ideal for demanding, high-speed machinery.
S71914 CB/P4A Bearing Model Code Explained, Specifications & Naming Convention
The model number S71914 CB/P4A is decoded as follows:
- S: Denotes a bearing from a high-precision series.
- 7: Identifies the bearing type as an angular contact ball bearing.
- 1914: Specifies the size series; 19 indicates a light series and 14 a 70mm bore.
- CB: Indicates a specific contact angle (15°) and internal clearance for a universal matched arrangement.
- P4A: Specifies the tolerance class P4 (ABEC-7) with enhanced dimensional and running accuracy requirements.
S71914 CB/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single-row design with a 15° contact angle and preload provides high axial and radial rigidity, ensuring precise shaft positioning and minimal deflection under load.
- Superior Load Capacity: Engineered to handle significant axial loads in one direction and combined (radial and axial) loads, thanks to the optimized contact angle and high-quality chrome steel construction.
- High-Speed Capability: The lightweight phenolic resin cage ensures stability and reduced centrifugal forces, contributing to a high limiting speed of 18,000 rpm. The bearing is pre-lubricated for immediate operation and sustained performance at high velocities.
- Sealed and Lubricated for Longevity: The sealed design protects against contamination and retains lubrication, extending service life and enabling reliable operation within a temperature range of -30°C to 110°C.
S71914 CB/P4A Bearing Typical Application Areas
This high-precision angular contact ball bearing is ideally suited for applications demanding high speed, accuracy, and rigidity, including:
- Machine Tool Spindles
- High-Speed Precision Spindles
- Grinding Applications
- Industrial Pumps and Compressors
- Precision Instrumentation and Robotics
