7016 ACD/P4ADGA Bearing Product Overview & Core Advantages
The 7016 ACD/P4ADGA is a precision angular contact ball bearing engineered for applications demanding exceptional rotational accuracy and rigidity. Operating under the stringent P4A tolerance class, this bearing is designed to simultaneously handle combined radial and axial loads. Its Universal Matchable (SU) design allows two bearings to be paired in a universal arrangement, simplifying installation and ensuring optimal preload and performance. With a 25° contact angle and an Extra light (Class A) preload, it delivers high running accuracy and is ideally suited for high-speed, high-reliability machinery.
7016 ACD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
The model number 7016 ACD/P4ADGA is decoded as follows:
- 7016: Standard series designation (Bore: 80 mm, Outside: 125 mm, Width: 44 mm).
- A: Signifies a 25° contact angle.
- CD: Indicates a Universal Matchable (SU) bearing. Two bearings can be universally paired (DB, DF, or DT arrangements).
- P4A: Denotes a super-precision tolerance class exceeding ABEC 7/ISO P4 standards, with specific running accuracy requirements.
- DGA: Specifies an Extra light preload (Class A).
7016 ACD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The angular contact design and phenolic cage provide high rigidity, enabling the bearing to support significant combined loads.
- Super-Precision Performance: Manufactured to P4A tolerance class with a 25° contact angle, it ensures minimal runout and vibration for superior operational accuracy.
- Optimized for High-Speed Operation: The lightweight phenolic cage and optimized internal geometry contribute to a high limiting speed of 28,000 rpm, making it an excellent high-speed bearing.
- Universal Matching Simplifies Installation: The Universal Matchable (SU) feature allows for flexible mounting configurations (face-to-face, back-to-back, or tandem) without selective assembly, reducing complexity and cost.
- Durable Construction: Components made from chrome steel offer high strength and durability for long service life in demanding conditions.
7016 ACD/P4ADGA Bearing Typical Application Areas
This high-precision bearing is ideally deployed in:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- Aerospace Control Systems
- Medical and Dental Equipment
