7016 CD/P4AQBTC Bearing Product Overview & Core Advantages
The 7016 CD/P4AQBTC is a precision angular contact ball bearing configured in a Quadruplex Tandem Back-to-Back (QBT) matched set. This arrangement is engineered to deliver exceptional axial rigidity and handle combined loads from multiple directions. Manufactured to the exacting P4A tolerance class, it is designed for applications demanding the highest levels of rotational accuracy and operational reliability. The moderate preload (Class C) ensures optimal performance from installation, minimizing deflection under load.
7016 CD/P4AQBTC Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7016 | Basic bearing series and size designation (80mm bore, 125mm OD). |
| C | Specifies a 15° contact angle, optimized for high axial load capacity. |
| D | Indicates a moderate preload (Class C) for enhanced stiffness. |
| P4A | Denotes a high-precision tolerance class superior to ABEC 7. |
| QBT | Signifies the Quadruplex Tandem Back-to-Back matched arrangement of four bearings. |
| C (in QBT suffix) | Specifies the universal matching level for the set (in this case, standard, not universal). |
7016 CD/P4AQBTC Bearing Structural Features & Performance Benefits
- Superior Rigidity and Load Capacity: The Quadruplex Tandem Back-to-Back (QBT) configuration provides maximum resistance to moment loads and offers extremely high axial and radial rigidity. This design enables the bearing set to support substantial combined loads.
- Precision Engineering: Manufactured to P4A tolerance standards with a 15° contact angle, this bearing ensures minimal runout and vibration, which is critical for high-speed applications.
- High-Speed Capability: The lightweight and robust phenolic cage minimizes centrifugal forces, contributing to a high limiting speed of 28,000 rpm. The open design facilitates efficient lubrication management.
- Durable Construction: Components made from chrome steel provide high hardness, wear resistance, and a long operational lifespan under demanding conditions.
7016 CD/P4AQBTC Bearing Typical Application Areas
This high-precision, high-rigidity bearing set is ideally suited for the most demanding industrial applications, including:
- Machine Tool Spindles: For high-speed milling, grinding, and turning centers requiring extreme accuracy and stiffness.
- Precision Gearboxes: Where low noise, high torque, and minimal axial play are critical.
- High-Frequency Spindles: Used in PCB drilling and other applications requiring very high rotational speeds.
- Industrial Pumps and Compressors: For handling significant axial and radial loads in continuous duty cycles.
