7010 CDGA/P4A Bearing Product Overview & Core Advantages
The 7010 CDGA/P4A is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Manufactured to P4A tolerance class, this bearing delivers superior running accuracy and dimensional stability. Its 15° contact angle and extra light preload (Class A) make it ideally suited for high-speed spindle applications where minimal friction and heat generation are critical. As a Universal Matchable (SU) bearing, it can be supplied in sets of three for simplified mounting and optimal preload configuration in complex arrangements.
7010 CDGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7010 | Standard bearing series designation, indicating a 50mm bore and 80mm outside diameter. |
| C | Specifies a 15° contact angle. |
| DG | Indicates the bearing is Universal Matchable (SU) and can be mounted in any combination (DB, DF, DT). |
| A | Denotes an Extra Light Preload (Class A). |
| P4A | Specifies the high-precision tolerance class, exceeding ABEC-7 standards. |
7010 CDGA/P4A Bearing Structural Features & Performance Benefits
- High-Speed Performance: The phenolic resin cage and optimized internal geometry contribute to a high limiting speed of 41,000 rpm, reducing centrifugal forces and maintaining stability.
- Exceptional Rigidity and Accuracy: Manufactured to P4A tolerance class with a 15° contact angle, this bearing provides high system stiffness and precise rotational performance, essential for machining accuracy.
- Optimized Load Capacity: The design effectively supports combined radial and axial loads, with a dynamic load rating of 6660 lbf and a static load rating of 5400 lbf.
- Pre-Configured Performance: The extra light preload (Class A) eliminates internal clearance, ensuring consistent performance from startup and reducing vibration and noise.
- Premium Materials: Constructed from chrome steel for rings and balls, ensuring high durability, wear resistance, and a long operational life under demanding conditions.
