7010 CB/P4A Bearing Product Overview & Core Advantages
The 7010 CB/P4A is a single-row angular contact ball bearing engineered for high-precision applications requiring exceptional rotational accuracy and rigidity. This P4 (ABEC-7) tolerance class bearing is designed to accommodate high combined loads, primarily thrust loads in one direction, while also supporting significant radial loads. Its 15° contact angle and phenolic resin cage contribute to superior high-speed performance, making it an ideal solution for machine tool spindles and other precision machinery where high rigidity and operational reliability are paramount.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 7010 | Basic bearing designation (50mm bore, 80mm OD) |
| CB | Specific internal design with moderate contact angle and optimized internal clearance for preload applications |
| P4 | High precision tolerance class (equivalent to ABEC-7) |
| A | Indicates 30° contact angle variant (note: product specifications indicate 15°, please verify application requirements) |
7010 CB/P4A Bearing Structural Features & Performance Benefits
High Precision & Rigidity: Manufactured to P4 tolerance class with strict dimensional control, this bearing delivers exceptional running accuracy. The optimized internal geometry and 15° contact angle provide superior stiffness against combined loading conditions.
Optimized High-Speed Performance: The phenolic resin cage offers excellent strength-to-weight ratio, reducing centrifugal forces and enabling limiting speeds up to 36,000 rpm. This makes it suitable for demanding high-speed applications.
Superior Load Capacity: With a dynamic load rating of 2239 lbf and static load rating of 1755 lbf, this bearing efficiently handles significant combined radial and axial loads.
Preload Capability: The CB designation indicates suitability for preload applications, allowing for precise control of bearing stiffness and minimizing axial and radial runout in critical applications.
