7016 CB/P4A Bearing Product Overview & Core Advantages
The 7016 CB/P4A is a single row angular contact ball bearing designed for high-precision applications demanding exceptional rotational accuracy and rigidity. Its primary advantage lies in its ability to accommodate combined loads—simultaneously handling significant radial loads and axial loads in one direction. Manufactured to P4 (ABEC-7) tolerance class, it guarantees ultra-precise running accuracy, making it ideal for high-speed spindles and other critical machinery where minimal runout and vibration are paramount. The phenolic cage and optimized internal geometry contribute to its high-speed capability and smooth operation.
7016 CB/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 7016 | Basic Bearing Series & Size | Denotes a metric, single row angular contact bearing with an 80mm bore, 125mm OD, and 22mm width. |
| CB | Contact Angle & Internal Clearance | Indicates a 15° contact angle and specific internal geometry optimized for high rigidity and moderate preload when mounted in pairs. |
| P4A | Tolerance Class | Signifies compliance with the P4 (ABEC-7) precision class, ensuring extremely tight dimensional and running accuracy tolerances. |
7016 CB/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The 15° contact angle and robust construction enable the bearing to support substantial combined radial and axial loads. The optimized raceway and ball geometry distribute stress evenly, enhancing load-carrying capacity and service life.
- Superior High-Speed Performance: The lightweight phenolic resin cage ensures excellent dimensional stability and low friction at high rotational speeds, contributing to a limiting speed of 20,000 rpm. This cage material also offers good slip characteristics and is suitable for demanding lubrication conditions.
- Exceptional Precision and Running Accuracy: As a P4 precision bearing, it features extremely tight tolerances on bore, outer diameter, and width. This results in minimal runout and vibration, which is critical for applications like machine tool spindles and precision instruments.
- Optimized Material Selection: Manufactured from high-grade chrome steel for both rings and balls, the bearing provides high hardness, wear resistance, and long-term dimensional stability under load and at elevated temperatures.
7016 CB/P4A Bearing Typical Application Areas
This precision angular contact ball bearing is engineered for high-performance applications, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Grinding Spindles: Internal and external grinding machines.
- High-Frequency Motors and Spindles: Applications requiring high rotational accuracy and speed.
- Robotics: High-precision joints and arm linkages.
- Medical Equipment: Dental handpieces and imaging device rotors.
