S71914 CB/HCP4ADGA Bearing Product Overview & Core Advantages
The S71914 CB/HCP4ADGA is a high-precision double row angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and reliability. Its design is optimized to support combined loads, simultaneously handling significant radial loads and bidirectional axial loads. A key advantage is its universal matchable (SU) design, allowing two bearings to be paired in a pre-set arrangement for simplified installation and optimal performance. Manufactured to an ultra-precise P4A tolerance class and featuring a phenolic cage and ceramic balls, this bearing is built for high-speed operation and delivers superior rigidity in a compact cross-section.
S71914 CB/HCP4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| S | Stainless Steel Bearing Ring | Enhanced corrosion resistance. |
| 71914 | Basic Bearing Series & Size Designation | Defines the 70 mm bore, 100 mm OD, and 32 mm width dimensions. |
| CB | Universal Matchable Bearing | Two bearings can be universally paired (SU) to achieve a specific preload without selective mounting. |
| HC | Hybrid Ceramic (Ceramic Balls, Steel Rings) | Reduced friction, higher speed capability, and longer service life. |
| P4A | Tolerance Class (Geometric & Running Accuracy) | Ultra-high precision for applications with minimal run-out and vibration requirements. |
| DGA | Contact Angle (15°) | Optimized for applications requiring a balance of axial and radial load capacity. |
S71914 CB/HCP4ADGA Bearing Structural Features & Performance Benefits
High Rigidity and Load Capacity: The double row angular contact design provides a rigid support system, enabling the bearing to withstand substantial combined loads (radial and bidirectional axial) without sacrificing performance.
Superior High-Speed Performance: The combination of a lightweight, robust phenolic cage and low-friction ceramic balls significantly reduces centrifugal forces and operating temperatures, allowing for a high limiting speed of 28,000 rpm.
Pre-optimized for Precision: As a universal matchable bearing, it is supplied with a pre-set internal clearance (Extra light / Class A preload) when paired, ensuring immediate optimal performance and simplified installation in precision spindles and assemblies.
Sealed and Lubricated for Life: The sealed design with factory-applied grease protects against contamination and provides long-term, maintenance-free operation within the specified temperature range of -30°C to 110°C.
S71914 CB/HCP4ADGA Bearing Typical Application Areas
The S71914 CB/HCP4ADGA is ideally suited for high-performance machinery where precision, speed, and reliability are paramount. Key application areas include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Instrumentation: Measuring and testing equipment.
- High-Frequency Motors and Spindles: Applications requiring extreme rotational accuracy.
