7016 ACDGB/P4A Bearing Product Overview & Core Advantages
The 7016 ACDGB/P4A is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. As a single bearing with a Universal Matchable (SU) designation, it can be universally paired with other bearings from the same manufacturing lot to form a precisely matched set, simplifying installation and ensuring optimal preload and performance. Its P4A tolerance class guarantees superior dimensional and running accuracy, making it ideal for high-speed spindles and other high-rigidity applications where minimal runout is critical.
7016 ACDGB/P4A Bearing Model Code Explained, Specifications & Naming Convention
The model number 7016 ACDGB/P4A is decoded as follows:
- 7016: Basic series designation, indicating a metric angular contact ball bearing with an 80mm bore and 125mm outside diameter.
- AC: Angular Contact design with a 25° contact angle.
- D: Signifies a specific internal design and high-precision construction.
- GB: Indicates a Light preload / Class B.
- P4A: Denotes an ultra-precision tolerance class exceeding ABEC 7 standards, ensuring extremely tight dimensional and running accuracy.
7016 ACDGB/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The optimized 25° contact angle and robust construction enable the bearing to support significant combined loads (radial and axial) simultaneously, providing a high-rigidity solution for machine tool spindles.
- Precision and Speed: Manufactured to P4A tolerance class, it ensures minimal vibration and heat generation. Combined with the lightweight Phenolic cage, it achieves a high limiting speed of 28,000 rpm, suitable for high-speed applications.
- Universal Matching: As a Universal Matchable (SU) bearing, it allows for flexible arrangement in sets (typically 3 bearings) without selective matching, reducing inventory complexity and ensuring consistent performance in preloaded configurations.
- Material Quality: Manufactured from high-grade Chrome Steel for both rings and balls, ensuring long service life and reliability under demanding operating conditions.
7016 ACDGB/P4A Bearing Typical Application Areas
This precision bearing is ideally suited for high-performance machinery where accuracy, speed, and rigidity are paramount. Key applications include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Grinding Spindles
- High-Frequency Motors
- Industrial Pumps and Compressors
- Medical and Dental Equipment
- Aerospace Actuation Systems
