7020 ACDTP/P4B Bearing Product Overview & Core Advantages
The 7020 ACDTP/P4B is a single-row angular contact ball bearing designed for applications demanding high precision and superior rigidity. Engineered to a P4 (ABEC-7) tolerance class, it excels in handling combined loads, particularly substantial axial loads in one direction, thanks to its defined 25° contact angle. Its compact design, featuring a phenolic cage and preloaded configuration, makes it an ideal solution for high-speed, high-reliability machinery where rotational accuracy is paramount.
7020 ACDTP/P4B Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| AC | Angular Contact design, optimized for combined radial and axial loads. |
| DTP | Indicates a specific internal design and preload level for enhanced stiffness and precise shaft positioning. |
| P4B | Denotes a high-precision tolerance class equivalent to ABEC-7, ensuring minimal runout and superior running accuracy. |
7020 ACDTP/P4B Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The combination of a 25° contact angle and factory-applied preload ensures maximum system stiffness, minimizing deflection under load and maintaining exceptional rotational accuracy.
- Optimized Load Capacity: Engineered to support significant combined loads, with a high radial dynamic load rating of 17,842 lbf and a static rating of 18,000 lbf, making it robust for demanding applications.
- High-Speed Capability: The lightweight and durable phenolic resin cage reduces centrifugal forces, contributes to low friction, and supports a high limiting speed of 8,000 rpm.
- Superior Material Construction: Manufactured from chrome steel for both rings and balls, providing high fatigue resistance and long service life.
