7016 CD/P4ADGC Bearing Product Overview & Core Advantages
The 7016 CD/P4ADGC is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Engineered to a P4A tolerance class, this bearing is optimized to handle combined loads—significant radial and axial loads in one direction. Its universal matchable (SU) design allows for flexible mounting in pairs to accommodate bidirectional axial loads or increase system rigidity. With a moderate preload (Class C) and a phenolic cage, it offers superior high-speed performance and operational stability, making it an ideal choice for high-precision, high-reliability machinery.
7016 CD/P4ADGC Bearing Model Code Explained, Specifications & Naming Convention
The model number 7016 CD/P4ADGC provides detailed technical specifications:
- 7016: Basic bearing series and size designation (80mm bore, 125mm OD, 44mm width).
- C: Denotes a 15° contact angle, optimized for high axial load capacity.
- D: Indicates the bearing is supplied as part of a universally matchable pair (SU).
- P4A: Specifies the tolerance class, indicating very high dimensional and running accuracy.
- DGC: Signifies the combination of features including the universal match pair designation and the specific preload/clearance group.
7016 CD/P4ADGC Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design and 15° contact angle provide excellent resistance to combined radial and axial loads. The universal matchable pairing enables simple arrangement in duplex sets (DB, DF, DT) to handle complex loading conditions and significantly increase system stiffness.
- High-Speed Performance: The lightweight phenolic resin cage ensures stable operation and reduced centrifugal forces at high speeds, contributing to the high limiting speed of 28,000 rpm. The moderate preload minimizes deflection under load while maintaining smooth rotation.
- Precision Engineering: Manufactured to P4A tolerance class, this bearing guarantees minimal runout and vibration, which is critical for applications requiring extreme positional accuracy and smooth motion.
- Durable Construction: Made from chrome steel for both rings and balls, the bearing offers high fatigue life and wear resistance. The open design allows for efficient lubrication management.
7016 CD/P4ADGC Bearing Typical Application Areas
This high-precision angular contact ball bearing is ideally suited for:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Gearboxes and Robotic Drives.
- High-Frequency Motors and Spindle Drives.
- Medical Equipment and Analytical Instruments.
- Aerospace Actuation Systems and Test & Measurement Equipment.
