7016 ACD/P4A Bearing Product Overview & Core Advantages
The 7016 ACD/P4A is a single-row angular contact ball bearing designed for applications demanding exceptional precision and rigidity. Engineered to a P4 (ABEC-7) tolerance class, it offers superior running accuracy. Its key advantage lies in its ability to accommodate high combined loads, efficiently handling both radial and significant axial loads in one direction. The 25° contact angle and availability of preload contribute to its high system rigidity, making it an ideal choice for high-speed spindles and other precision machinery where positional accuracy is critical.
7016 ACD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7016 | Basic bearing series and size designation (80mm bore, 125mm OD, 22mm width). |
| ACD | Signifies a 25° contact angle and that the bearing is designed for a specific, optimized internal geometry for high performance. |
| P4A | Indicates the tolerance class P4 (ABEC-7), denoting very high precision levels for dimensional and running accuracy. |
Note: This is an open bearing, supplied lubricated from the factory.
7016 ACD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The 25° contact angle and availability of preload enable this bearing to provide high axial and radial stiffness, minimizing deflection under load for superior machining accuracy.
- Optimized Load Capacity: The angular contact design is engineered to support high combined loads, making it suitable for applications with significant radial and one-direction axial forces.
- High-Speed Capability: The lightweight phenolic resin cage reduces centrifugal forces, contributing to a high limiting speed of 15,000 rpm. This, combined with the optimized internal geometry, ensures stable operation at high rotational speeds.
- Premium Material Construction: Manufactured from chrome steel for both rings and balls, ensuring high durability, wear resistance, and a long operational life under demanding conditions.
7016 ACD/P4A Bearing Typical Application Areas
The 7016 ACD/P4A is specified for high-performance applications where precision, speed, and rigidity are non-negotiable. Key industries and equipment include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Gearboxes: Especially in high-speed or high-torque stages.
- High-Frequency Motors and Spindles: Used in PCB drilling, dental handpieces, and small precision tooling.
- Robotics: High-accuracy joints and rotary actuators.
