7036 CD/P4ADGB Bearing Product Overview & Core Advantages
The 7036 CD/P4ADGB is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Manufactured to P4A tolerance class, this bearing is engineered to handle combined loads with high reliability. Its universal matchable (SU) design allows two bearings to be paired in a back-to-back or face-to-face arrangement, providing excellent operational stability and system rigidity. The phenolic cage and optimized 15° contact angle contribute to superior high-speed performance, making it an ideal solution for high-precision spindles and other demanding machinery.
7036 CD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| CD | Indicates a universal matchable bearing designed with a specific internal clearance and geometric accuracy for optimal pairing in duplex sets. |
| P4A | Denotes an ultra-precision tolerance class with extremely tight limits on bore, outer diameter, and width tolerances, ensuring minimal runout and vibration. |
| DGB | Signifies a light preload (Class B) applied to the bearing, which enhances system rigidity and positional accuracy while minimizing heat generation at high speeds. |
7036 CD/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design and universal matching capability enable the bearing to support significant combined radial and axial loads. When mounted in pairs, the system stiffness is dramatically increased, crucial for applications requiring high positional accuracy.
- Superior High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the 15° contact angle provides an excellent balance between axial load capacity and speed capability, achieving a limiting speed of 16,250 rpm.
- Precision & Stability: Manufactured to P4A tolerance class with extremely tight dimensional tolerances, this bearing ensures minimal runout and smooth, quiet operation, which is vital for precision machining and measurement equipment.
- Optimized for Matched Sets: The Universal Matchable (SU) designation means two bearings are supplied as a pre-engineered pair, guaranteeing optimal preload and performance when installed in a duplex configuration, simplifying assembly and ensuring reliability.
7036 CD/P4ADGB Bearing Typical Application Areas
This bearing is specifically engineered for high-performance applications where precision, speed, and rigidity are paramount. Key industries and machinery include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Instrumentation: High-accuracy measuring and testing equipment.
- High-Frequency Motors and Spindles: Applications requiring rapid acceleration and deceleration.
- Aerospace & Defense Systems: Gyroscopes, radar systems, and other critical rotational mechanisms.
