7016 CD/P4AQBCB Bearing Product Overview & Core Advantages
The 7016 CD/P4AQBCB is a precision angular contact ball bearing configured in a Quadruplex Back-to-Back (QBC) matched set. Engineered for the most demanding applications, this bearing delivers exceptional high rigidity and can accommodate combined loads (radial and axial). Its P4A tolerance class ensures superior running accuracy, making it ideal for high-speed, high-precision machinery requiring maximum stability and performance.
7016 CD/P4AQBCB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7016 | Basic bearing series and size designation (80mm bore, 125mm OD). |
| C | 15° contact angle, optimized for high-speed operation and axial load capacity. |
| D | Indicates a modified internal design for optimized performance. |
| P4A | High precision tolerance class, providing extremely tight dimensional and running accuracy. |
| QBCB | Quadruplex Back-to-Back (QBC) matched set with Light preload (Class B). This arrangement provides maximum rigidity and moment load capacity. |
7016 CD/P4AQBCB Bearing Structural Features & Performance Benefits
- Superior Rigidity & Moment Load Capacity: The Quadruplex Back-to-Back (QBC) arrangement creates an extremely stiff bearing system, effectively resisting complex moment loads and ensuring precise shaft positioning.
- Optimized for High Speeds: The 15° contact angle and phenolic cage are engineered for stable operation at high rotational speeds, with a limiting speed of 28,000 rpm.
- High Load Capacity: Manufactured from chrome steel and featuring a robust design, this bearing offers high dynamic and static load ratings (39,150 lbf / 55,125 lbf) for long service life under demanding conditions.
- Pre-Configured Performance: The set is supplied with a light preload (Class B) and is pre-lubricated, ensuring immediate, optimal performance upon installation without the need for initial adjustment.
