7032 ACDGB/P4A Bearing Product Overview & Core Advantages
The 7032 ACDGB/P4A is a single-row angular contact ball bearing engineered for applications demanding high precision and exceptional running accuracy. Operating under a Light preload (Class B), it delivers superior axial rigidity and minimizes deflection under complex loads. Manufactured to the stringent P4A tolerance class, this bearing is Universal Matchable (SU), allowing for precise axial preload adjustment when mounted in sets. Its optimized design is ideal for high-speed spindles and other machinery requiring uncompromising accuracy and reliability.
7032 ACDGB/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 7032 | Basic bearing designation, indicating a metric series with a 160mm bore and 240mm outside diameter. |
| AC | Angular Contact design with a 25° contact angle for handling combined radial and axial loads. |
| DGB | Duplex arrangement designation, indicating the bearing is ground for Universal Matching (SU) and is part of a set of 3. |
| P4A | The tolerance class, signifying extremely high precision levels for inner and outer ring runouts and dimensions. |
7032 ACDGB/P4A Bearing Structural Features & Performance Benefits
High Precision & Rigidity: Manufactured to P4A tolerances and supplied with a Light preload, this bearing ensures minimal runout and high system stiffness, critical for precision applications.
Optimized Load Capacity: The 25° contact angle is engineered to efficiently support significant combined loads (radial and axial). With a dynamic load rating of 40,950 lbf and a static load rating of 45,900 lbf, it offers robust performance.
High-Speed Capability: The lightweight, high-strength phenolic cage and precision-ground chrome steel components contribute to a high limiting speed of 6,300 rpm, reducing friction and heat generation.
Matched Set Performance: As a Universal Matchable (SU) bearing supplied in a set of 3, it allows for flexible mounting configurations (DB, DF, DT) to achieve the exact preload and rigidity required by the application.
7032 ACDGB/P4A Bearing Typical Application Areas
The 7032 ACDGB/P4A is ideally suited for high-performance machinery where precision and speed are paramount. Key industries and equipment include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Robotics: Arm joints and rotary actuators requiring high positional accuracy.
