7016 ACD/P4AQBCC Bearing Product Overview & Core Advantages
The 7016 ACD/P4AQBCC is a precision quadruplex matched set of angular contact ball bearings designed for applications demanding exceptional rigidity and accuracy. This P4A tolerance class bearing is pre-configured in a Back-to-Back (QBC) arrangement, providing superior stability and the ability to handle combined loads—significant radial and thrust loads from both directions simultaneously. Its moderate preload (Class C) ensures optimal running accuracy and stiffness right from installation, making it ideal for high-precision, high-rigidity machinery.
7016 ACD/P4AQBCC Bearing Model Code Explained, Specifications & Naming Convention
The model number 7016 ACD/P4AQBCC is decoded as follows:
- 7016: Basic bearing series, with 80 mm bore and 125 mm outside diameter.
- AC: Angular Contact design with a 25° contact angle.
- D: Signifies a duplex (two-bearing) set. The "Q" in the suffix indicates four such sets are matched.
- P4A: Denotes a super-precision tolerance class, exceeding ABEC 7 standards, for exceptional running accuracy.
- QBCC: Specifies the matched arrangement and preload.
- Q: Quadruplex set (four bearings).
- B: Back-to-Back mounting arrangement.
- C: Moderate preload (Class C).
- C: Universal matching not required (standard).
7016 ACD/P4AQBCC Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The quadruplex back-to-back arrangement creates a highly rigid bearing system that effectively resists moment loads and manages heavy combined radial and axial loads.
- Precision Performance: Manufactured to P4A tolerance class with a 25° contact angle, this bearing delivers exceptional running accuracy and low noise operation, which is critical for high-speed spindles.
- Optimized High-Speed Operation: The lightweight phenolic resin cage reduces centrifugal forces, contributing to a high limiting speed of 28,000 rpm. The bearings are pre-lubricated for immediate operation.
- Durable Construction: Both rings and balls are made from high-grade chrome steel, ensuring long service life and consistent performance under demanding conditions within a temperature range of -30°C to 110°C.
7016 ACD/P4AQBCC Bearing Typical Application Areas
This precision matched bearing set is engineered for the most demanding applications, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Grinding Spindles
- High-Frequency Machining Centers
- Industrial Pumps and Compressors
- Other high-performance machinery requiring maximum rigidity and rotational accuracy.
