7010 CEGA/P4A Bearing Product Overview & Core Advantages
The 7010 CEGA/P4A is a single-row angular contact ball bearing engineered for ultra-precision applications requiring exceptional rotational accuracy and high-speed capability. Manufactured to P4A tolerance class with extra light preload (Class A), this bearing delivers superior running precision and minimal vibration. Its optimized 15° contact angle provides excellent performance for combined loads, particularly where high axial stiffness is required. The bearing comes universally matchable (SU), allowing for precise axial play adjustment when mounted with other bearings.
7010 CEGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7010 | Standard bearing series with 50mm bore diameter and 80mm outside diameter |
| CE | Enhanced internal design with optimized contact geometry and surface finish |
| GA | Universal matching bearing with specific axial clearance group |
| P4A | High precision tolerance class with enhanced dimensional and running accuracy |
7010 CEGA/P4A Bearing Structural Features & Performance Benefits
Precision Engineering: Manufactured to P4A tolerance class with bore and outside diameter tolerances of -0.004mm to 0, ensuring exceptional dimensional stability and running accuracy.
High-Speed Capability: Features a phenolic resin cage that reduces centrifugal forces, enabling operation at limiting speeds up to 41,000 rpm while maintaining stability.
Superior Load Capacity: With a radial dynamic load rating of 3510 lbf and radial static load rating of 2385 lbf, the bearing handles significant combined loads efficiently.
Optimized Internal Geometry: The 15° contact angle and precision-ground chrome steel balls (7.938mm diameter, 21 balls) provide excellent axial stiffness and smooth operation.
Temperature Performance: Suitable for operating temperatures from -30°C to 110°C, maintaining performance across diverse environmental conditions.
