S7007 ACDTP/P4B Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single-row angular contact design with a 25° contact angle and factory-applied preload delivers superior axial and radial stiffness, minimizing deflection under load for exceptional positional accuracy.
- Superior Load Capacity: Engineered to support combined loads efficiently, with a dynamic load rating of 3330 lbf and a static load rating of 2025 lbf, making it robust for demanding applications.
- Optimized High-Speed Performance: The lightweight, high-strength phenolic resin cage and precision-ground chrome steel components enable a high limiting speed of 20,000 rpm, reducing centrifugal forces and operating temperatures.
- Sealed and Lubricated for Life: As a sealed bearing pre-lubricated with high-performance grease, it is protected from contamination and is effectively maintenance-free within its specified operating temperature range of -30°C to 110°C.
S7007 ACDTP/P4B Bearing Typical Application Areas
