7016 ACD/P4ADBD Bearing Product Overview & Core Advantages
The 7016 ACD/P4ADBD is a precision duplex angular contact ball bearing designed for demanding applications requiring exceptional rigidity and accuracy. This matched back-to-back arrangement provides superior stability under combined loads, effectively handling radial forces and bidirectional axial thrust. With a P4A tolerance class and heavy preload (Class D), it delivers outstanding rotational precision and is engineered for high-performance scenarios where maximum system stiffness is critical.
7016 ACD/P4ADBD Bearing Model Code Explained, Specifications & Naming Convention
The model number 7016 ACD/P4ADBD is decoded as follows:
- 7016: Basic bearing series, indicating a 80 mm bore, 125 mm outside diameter, and 44 mm width.
- AC: Angular Contact design with a 25° contact angle.
- D: Indicates a Duplex (two-bearing) set.
- P4A: Denotes a very high precision tolerance class, exceeding ABEC 7 standards.
- DB: Specifies the Back-to-Back mounting arrangement of the duplex pair.
- Heavy Preload (Class D): A significant internal preload is applied to maximize bearing rigidity.
7016 ACD/P4ADBD Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The duplex back-to-back (DB) configuration creates a wide, rigid support system that effectively counters moment loads and ensures exceptional operational stability.
- Superior Load Capacity: Engineered with a 25° contact angle and robust construction, this bearing is optimized to carry significant combined radial and axial loads simultaneously.
- Precision Performance: Manufactured to P4A tolerance class with a phenolic cage, it guarantees minimal runout and smooth operation, essential for high-speed accuracy.
- Optimized for High-Speed Operation: The lightweight phenolic cage and precision-ground components contribute to a high limiting speed of 28,000 rpm, making it suitable for high-speed applications.
- Durability & Reliability: Constructed from chrome steel for both rings and balls, it offers excellent wear resistance and a long service life under heavy preload conditions.
7016 ACD/P4ADBD Bearing Typical Application Areas
This bearing is ideally suited for high-precision, high-rigidity machinery, including:
- Machine Tool Spindles
- High-Speed Grinding Heads
- Precision Gearboxes
- Industrial Pumps and Compressors
- Robotic Arm Joints and Precision Axes
