7016 CD/P4ADBB Bearing Product Overview & Core Advantages
The 7016 CD/P4ADBB is a precision duplex angular contact ball bearing designed for applications requiring exceptional rotational accuracy and high rigidity. This matched set back-to-back (DB) arrangement is preloaded to Light / Class B specifications, ensuring minimal axial and radial play for superior stability under combined loads. Manufactured to P4A tolerance class, it delivers outstanding running accuracy, making it ideal for high-speed spindles and other precision machinery where uncompromising performance is critical.
7016 CD/P4ADBB Bearing Model Code Explained, Specifications & Naming Convention
The model number 7016 CD/P4ADBB is decoded as follows:
- 7016: Standard bearing series designation (70 series, 80mm bore, 125mm OD).
- C: 15° contact angle, optimized for carrying combined radial and axial loads.
- D: Indicates a duplex bearing (two bearings as a set).
- P4A: Denotes a super-precision tolerance class, exceeding ABEC 7 standards for exceptional dimensional and running accuracy.
- DB: Specifies the Back-to-Back mounting arrangement, which provides high moment rigidity and excellent stability.
7016 CD/P4ADBB Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The duplex back-to-back (DB) design and light preload create a highly rigid bearing system that effectively resists operational moments and deflection, ensuring precise shaft positioning.
- Superior Load Capacity: With a 15° contact angle and robust construction, this bearing efficiently handles combined radial and axial loads from both directions simultaneously.
- Precision High-Speed Performance: The Phenolic (resin) cage offers low weight and excellent sliding properties, contributing to smooth operation and a high limiting speed of 28,000 rpm. The P4A tolerance ensures low vibration and heat generation at high velocities.
- Optimized Material & Lubrication: Components made from high-grade Chrome Steel provide durability and wear resistance. The bearing is supplied lubricated for immediate use, suitable for a wide operating temperature range.
7016 CD/P4ADBB Bearing Typical Application Areas
This precision angular contact bearing is engineered for the most demanding applications, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Grinding Spindles
- High-Frequency Motors
