7016 ACE/P4ADGA Bearing Product Overview & Core Advantages
The 7016 ACE/P4ADGA is a precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. As part of a universally matchable (SU) pair, it excels at handling combined loads, supporting significant radial and axial loads simultaneously. Manufactured to the stringent P4A tolerance class, it offers superior running accuracy and is pre-lubricated for immediate use, making it an ideal choice for high-performance machinery where reliability and precision are paramount.
7016 ACE/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACE | 25° contact angle and enhanced internal design for optimized load distribution. |
| P4A | High precision tolerance class with tighter limits on bore, outside diameter, and width for superior running accuracy. |
| DGA | Universal Matchable (SU) designation, indicating the bearing is supplied as one of a pair ground to be mounted in a universal arrangement (back-to-back or face-to-face). |
7016 ACE/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The 25° contact angle and robust construction enable the bearing to withstand high combined radial and axial loads. When used in a matched universal pair, the arrangement provides exceptional system rigidity and moment load capacity.
- Precision Performance: Manufactured to P4A tolerance standards, this bearing ensures minimal runout and vibration, which is critical for applications requiring high rotational accuracy.
- Optimized Cage Design: The phenolic cage offers excellent strength-to-weight ratio and operates smoothly at high speeds, contributing to the bearing's high limiting speed of 28,000 rpm.
- Ready-to-Install: The bearing comes pre-lubricated, simplifying installation and providing immediate protection upon startup.
7016 ACE/P4ADGA Bearing Typical Application Areas
This high-precision angular contact ball bearing is ideally suited for:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- Industrial Pumps and Compressors
- Robotic Arms and Precision Positioning Systems
