7016 ACD/P4ATGB Bearing Product Overview & Core Advantages
The 7016 ACD/P4ATGB is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high rigidity. Manufactured to P4A tolerance class, it delivers superior running precision. Its 25° contact angle and Universal Matchable (SU) design enable it to accommodate combined radial and axial loads simultaneously. The light preload (Class B) ensures minimal deflection and smooth operation, making it ideal for high-speed spindles and other high-precision machinery.
7016 ACD/P4ATGB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACD | Angular Contact Design with a 25° contact angle. |
| P4A | Indicates a high-precision tolerance class for superior dimensional and running accuracy. |
| TGB | Signifies the bearing is universally matchable (SU), allowing any bearing to be mounted with any other without pre-set axial clearance. |
7016 ACD/P4ATGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design and phenolic cage provide excellent stability, enabling the bearing to handle significant combined loads.
- Precision Performance: Manufactured to P4A tolerance standards with a light preload, this bearing ensures high running accuracy, reduced vibration, and minimal heat generation.
- Optimized for High Speeds: The lightweight phenolic resin cage and precision-ground chrome steel balls contribute to a high limiting speed of 28,000 rpm.
- Universal Matching Capability: The SU (Universal Matchable) feature simplifies installation in multi-bearing arrangements, as any bearing can be paired with another without requiring selective matching.
