7016 CD/P4ADBG33 Bearing Product Overview & Core Advantages
The 7016 CD/P4ADBG33 is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a duplex back-to-back (DB) matched set, this bearing is preloaded and configured to provide superior stability under combined loads, including significant radial and axial forces. Manufactured to the stringent P4A tolerance class, it ensures minimal runout and consistent high-speed performance. Its robust construction, featuring a phenolic cage and chrome steel components, makes it ideal for high-precision, high-reliability machinery where uncompromising performance is critical.
7016 CD/P4ADBG33 Bearing Model Code Explained, Specifications & Naming Convention
The model number 7016 CD/P4ADBG33 provides detailed technical specifications through its suffix codes:
- 7016: Basic designation indicating a 80mm bore, 125mm OD, 44mm width bearing.
- C: Denotes a 15° contact angle, optimized for handling high axial loads.
- D: Signifies the bearing is part of a duplex (DB) back-to-back arrangement.
- P4A: Indicates a super-precision tolerance class with enhanced dimensional and running accuracy.
- DB: Confirms the back-to-back mounting of the two bearings in the set.
- G33: Specifies a preload level for optimal rigidity and minimal deflection under operational loads.
7016 CD/P4ADBG33 Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The duplex back-to-back (DB) arrangement creates a rigid bearing system that effectively resists moment loads and shaft deflection, ensuring precise shaft positioning.
- Superior Load Capacity: The 15° contact angle and duplex design enable the bearing to support substantial combined radial and axial loads simultaneously.
- High-Speed Capability: The lightweight phenolic resin cage reduces centrifugal forces, while the precision-ground components contribute to a high limiting speed of 28,000 rpm.
- Precision Performance: Manufactured to P4A tolerance standards, this bearing guarantees extremely low vibration and noise levels, which is essential for smooth, high-accuracy operation.
- Optimized Material: Components made from high-grade chrome steel provide excellent wear resistance and durability for a long service life.
7016 CD/P4ADBG33 Bearing Typical Application Areas
The 7016 CD/P4ADBG33 is engineered for high-performance applications, including:
- Machine Tool Spindles: For milling, grinding, and turning centers requiring high rigidity and precision.
- High-Frequency Motors & Spindles: Where high rotational speeds and accuracy are paramount.
- Precision Gearboxes: In applications demanding minimal backlash and high positional accuracy.
- Industrial Pumps & Compressors: For handling significant axial and radial loads in demanding environments.
