S71922 ACD/HCP4A Bearing Product Overview & Core Advantages
The S71922 ACD/HCP4A is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and reliability. This single-row bearing is distinguished by its 25° contact angle and P4 (ABEC-7) tolerance class, enabling superior performance under combined radial and axial loads. Its construction with ceramic balls and a phenolic cage facilitates high-speed operation up to 8,500 rpm, while the preload availability ensures high system rigidity and minimal runout. The bearing comes lubricated and sealed for long-term, maintenance-free service in a wide temperature range.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 71922 | Bearing series and size designation (110mm bore, 150mm OD, 20mm width) |
| ACD | 25° contact angle, optimized for high axial load capacity and rigidity |
| HCP4A | Hybrid Ceramic construction (Ceramic balls), P4 precision class, preloaded |
S71922 ACD/HCP4A Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Design: The use of ceramic balls significantly reduces friction, heat generation, and wear, contributing to higher limiting speeds and extended service life compared to all-steel designs.
- High Rigidity & Precision: The 25° contact angle and available preload provide exceptional axial and radial stiffness, making it ideal for applications requiring precise shaft positioning and minimal deflection under load.
- Superior High-Speed Capability: The lightweight phenolic resin cage ensures stability and low centrifugal forces at high rotational speeds, while the hybrid construction further enhances the bearing's speed performance.
- Optimized Load Capacity: Engineered to handle significant combined loads, with a dynamic load rating of 13,162 lbf and a static load rating of 15,300 lbf.
- Sealed & Lubricated for Life: The integral seals protect against contamination, and the factory-applied lubricant ensures consistent performance across the specified temperature range from -30°C to 110°C, offering a maintenance-free solution.
