| Code Segment | Technical Meaning |
|---|---|
| S7010 | Basic bearing designation (50mm bore, 80mm OD) |
| CD | Contact angle of 15° |
| P4A | High precision tolerance class (superior to ABEC 7) |
| QBC | Quadruplex Back-to-Back matched set arrangement |
S7010 CD/P4AQBCA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design and QBC matched arrangement of four bearings provide exceptional system stiffness and the ability to withstand heavy combined radial and axial loads from multiple directions.
- Precision Performance: Manufactured to P4A tolerance class with tight dimensional controls on bore diameter, outside diameter, and width, ensuring minimal runout and vibration for smooth, accurate operation.
- Optimized High-Speed Operation: The lightweight phenolic cage and 15° contact angle contribute to lower friction and higher limiting speeds (46,000 rpm), making it an ideal high-speed bearing solution.
- Sealed & Lubricated for Life: The sealed design with factory-applied grease lubrication protects against contamination and provides long-term, maintenance-free operation within the specified temperature range (-30°C to 110°C).
S7010 CD/P4AQBCA Bearing Typical Application Areas
- Machine Tool Spindles for high-precision milling, grinding, and turning centers
- High-Speed Machining Centers requiring extreme accuracy and rigidity
