|---|---|
| S7010 | Basic bearing designation (50mm bore, 80mm OD, 16mm width). |
| C | 15° contact angle. |
| D | Enhanced internal design for high precision and speed. |
| G | Universal Matchable (SU) bearing for flexible mounting arrangements. |
| B | Light preload (Class B). |
| P4A | High precision tolerance class, exceeding ABEC 7 standards. |
S7010 CDGB/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: Manufactured to P4A tolerance with a 15° contact angle and a phenolic resin cage, this bearing provides excellent rotational accuracy and stiffness, minimizing deflection under load for superior machining or operational results.
- Superior Load Capacity: The optimized internal geometry and high-grade chrome steel construction enable it to handle high dynamic and static radial loads (6660 lbf and 5400 lbf respectively), as well as bidirectional axial loads.
- Optimized High-Speed Performance: The lightweight phenolic cage and precision-ground components contribute to a high limiting speed of 46,000 rpm, reducing centrifugal forces and heat generation.
- Sealed and Pre-Lubricated: As a sealed bearing pre-lubricated with grease, it is protected from contamination and is ready for immediate use, offering a long, maintenance-free service life within its specified temperature range of -30°C to 110°C.
S7010 CDGB/P4A Bearing Typical Application Areas
This precision angular contact ball bearing is ideally suited for high-performance applications where accuracy and speed are critical. Key industries and equipment include:
- Machine Tool Spindles: For CNC milling, grinding, and turning centers.
- High-Frequency Motors and Spindles: Enabling high-speed machining operations.
- Precision Instrumentation: Used in measuring devices and optical equipment.
