708 CD/P4ADGA Bearing Product Overview & Core Advantages
The 708 CD/P4ADGA is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Manufactured to P4A tolerance class, this bearing is optimized for high-speed operation and can accommodate combined radial and axial loads. Its extra light preload (Class A) ensures minimal running torque and precise shaft positioning, making it ideal for high-reliability, high-precision machinery. The bearing comes pre-lubricated and is part of a Universal Matchable (SU) set, allowing for versatile mounting configurations in pairs to support complex load requirements.
708 CD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 708 CD | Basic bearing designation, indicating a specific angular contact design and size series. |
| P4A | Indicates a high-precision tolerance class, specifying very tight dimensional and running accuracy tolerances. |
| DGA | Suffix denoting a Universal Matchable (SU) bearing pair with a specific contact angle and preload combination. The "GA" typically indicates a light/extra light preload and a 15° contact angle. |
708 CD/P4ADGA Bearing Structural Features & Performance Benefits
High Precision and Rigidity: Manufactured to P4A tolerance class, this bearing ensures minimal runout and vibration, providing superior rotational accuracy. The 15° contact angle and optimized internal geometry contribute to high system rigidity.
Combined Load Capacity: As an angular contact ball bearing, it is engineered to support significant combined radial and axial loads simultaneously, making it suitable for complex loading conditions.
High-Speed Performance: The use of a lightweight, durable phenolic resin cage and precision-ground chrome steel components allows for a high limiting speed of 110,000 rpm, ideal for demanding spindle applications.
Universal Matchability (SU): This bearing is designed as part of a Universal Matchable (SU) set. Two bearings can be mounted in various arrangements (back-to-back, face-to-face, or tandem) to optimize performance for specific application needs regarding stiffness and moment load capacity.
