7210 CD/P4ATGB Bearing Product Overview & Core Advantages
The 7210 CD/P4ATGB is a precision angular contact ball bearing designed for applications requiring exceptional rotational accuracy and high-speed performance. Manufactured to P4A tolerance class, this bearing delivers superior dimensional stability and running precision. Its 15° contact angle and Universal Matchable (SU) design enable it to handle significant combined loads (radial and axial) in either direction when mounted in sets. The phenolic cage and optimized internal geometry contribute to its high limiting speed of 41,000 rpm, making it an ideal solution for demanding, high-precision machinery.
7210 CD/P4ATGB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| CD | Signifies a 15° contact angle and a specific internal design optimized for high-speed operation and universal matching. |
| P4A | Indicates a high-precision tolerance class with enhanced running accuracy and dimensional control, superior to ABEC-7. |
| TGB | Specifies the use of a phenolic (resin) cage, which is lightweight and ideal for high-speed applications, offering excellent strength and guidance. |
7210 CD/P4ATGB Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: Manufactured to P4A tolerance standards with a bore diameter tolerance of -0.004mm to 0, ensuring precise shaft fits and minimal runout for superior system rigidity and accuracy.
- Optimized Load Capacity: The 15° contact angle design is engineered to support substantial combined radial and axial loads, with a dynamic load rating of 21,938 lbf and a static load rating of 22,950 lbf.
- Superior High-Speed Performance: The lightweight phenolic cage (TGB) reduces centrifugal forces, while the optimized internal geometry and open design allow for efficient lubrication management, enabling a high limiting speed of 41,000 rpm.
- Universal Matching Capability (SU): Bearings are universally matchable, allowing for flexible mounting in duplex pairs (back-to-back, face-to-face, or tandem) to create a stiff bearing system capable of handling complex load conditions.
7210 CD/P4ATGB Bearing Typical Application Areas
This bearing is ideally suited for high-performance applications, including:
- Machine Tool Spindles for milling, grinding, and turning centers
- High-Speed Precision Spindles in PCB drilling and routing machines
- Industrial Pumps and Compressors
- Robotic Arm Joints and Precision Gearboxes
