7016 CD/P4ADGB Bearing Product Overview & Core Advantages
The 7016 CD/P4ADGB is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a Universal Matchable (SU) bearing supplied in a pre-matched pair, it is engineered to accommodate combined loads—simultaneously handling radial and axial forces. Its P4A tolerance class ensures ultra-precise dimensions and running accuracy, making it ideal for high-speed spindles and other critical machinery. The light preload (Class B) minimizes deflection under operational stresses, enhancing system stability and performance.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 7016 | Basic bearing series and size designation (80mm bore, 125mm OD, 44mm width). |
| C | 15° contact angle, optimized for high axial load capacity. |
| D | Indicates a Universal Matchable (SU) bearing designed to be paired in a set. |
| P4A | Super-precision tolerance class for exceptional dimensional and running accuracy. |
| DB | Back-to-back matched arrangement of two bearings, providing high moment rigidity. |
7016 CD/P4ADGB Bearing Structural Features & Performance Benefits
The performance of the 7016 CD/P4ADGB is defined by its advanced construction. The phenolic cage ensures low friction and high-speed capability, contributing to a limiting speed of 28,000 rpm. The 15° contact angle and universal matchable design enable the bearing pair to handle significant combined loads with high rigidity. Manufactured from chrome steel for both rings and balls, it offers excellent durability and fatigue resistance. The light preload eliminates internal clearance, reducing noise and vibration while increasing system stiffness. This combination of features makes it a high-speed, high-rigidity solution for demanding applications.
