7016 ACDGA/P4AL Bearing Product Overview & Core Advantages
The 7016 ACDGA/P4AL is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Manufactured to P4A tolerance class, this bearing delivers superior running precision. Its 25° contact angle and extra light preload (Class A) are optimized for high-speed operation while providing excellent stability. As a Universal Matchable (SU) bearing, it can be precisely paired with others to form a rigid, pre-loaded set, making it ideal for supporting combined loads in sophisticated machinery.
7016 ACDGA/P4AL Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| AC | Angular Contact design with a 25° contact angle. |
| D | High Ball Complement design for increased load capacity. |
| GA | Universal Matchable bearing with specific axial internal clearance and preload. |
| P4A | High precision tolerance class (equivalent to ABEC 7), ensuring minimal runout and vibration. |
| L | Light pre-lubrication for initial operation. |
7016 ACDGA/P4AL Bearing Structural Features & Performance Benefits
High Rigidity and Load Capacity: The angular contact design and high ball complement (20 balls) enable the bearing to support significant combined radial and axial loads simultaneously. The 25° contact angle provides an optimal balance for thrust load capacity and high-speed capability.
Precision and High-Speed Performance: Manufactured to P4A tolerance standards with a phenolic resin cage, this bearing ensures smooth operation, low vibration, and a high limiting speed of 28,000 rpm. The cage material offers excellent strength-to-weight ratio and is suitable for high rotational speeds.
Superior Material and Construction: Both rings and balls are made from high-grade chrome steel, providing high durability and fatigue resistance. The tight dimensional tolerances on the bore, outside diameter, and width guarantee precise fitment and reliable performance in demanding applications.
7016 ACDGA/P4AL Bearing Typical Application Areas
- Machine Tool Spindles: For high-precision milling, grinding, and turning centers requiring extreme accuracy and rigidity.
- High-Frequency Motors and Spindles: Ideal for applications where high rotational speeds are critical.
- Precision Instrumentation: Used in measuring devices and scientific equipment where minimal runout is essential.
- Aerospace and Defense Systems: For gyroscopes, navigation systems, and other critical rotating assemblies.
