7017 ACD/P4AQBCC Bearing Product Overview & Core Advantages
The 7017 ACD/P4AQBCC is a precision quadruplex matched set of angular contact ball bearings designed for the most demanding applications. This P4A tolerance class set offers exceptional high rigidity and load-carrying capacity due to its back-to-back (QBC) arrangement. Engineered to handle combined loads (significant radial and axial loads simultaneously), it is preloaded for optimal performance and is ideal for high-precision, high-reliability machinery requiring superior rotational accuracy and stiffness.
7017 ACD/P4AQBCC Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACD | Angular Contact Design with a 25° contact angle. |
| P4A | Indicates a high-precision tolerance class exceeding ABEC 7/ISO P4 standards, ensuring minimal runout and superior dimensional accuracy. |
| QBCC | Defines the matched set configuration: Quadruplex (4 bearings), Back-to-Back arrangement, with Class C (Moderate) preload. |
7017 ACD/P4AQBCC Bearing Structural Features & Performance Benefits
- Extreme Rigidity and Stability: The quadruplex back-to-back (QBC) arrangement creates a highly rigid bearing system that effectively resists moment loads and shaft deflection, crucial for maintaining precision under heavy combined loads.
- Superior Load Capacity: The 25° contact angle and robust construction with a phenolic cage enable high radial and axial load ratings, making it suitable for applications with demanding combined load requirements.
- Optimized for Precision & Speed: The P4A tolerance class guarantees exceptional running accuracy. The lightweight phenolic cage contributes to lower friction and allows for a high limiting speed of 17,000 rpm, suitable for high-speed operations.
- Pre-lubricated & Ready for Service: The bearings come lubricated from the factory, ensuring immediate and reliable operation upon installation.
7017 ACD/P4AQBCC Bearing Typical Application Areas
This bearing set is ideally suited for high-performance machinery where maximum rigidity, precision, and load capacity are paramount. Key applications include:
- Machine Tool Spindles (e.g., high-speed milling, grinding)
- Precision Gearboxes
- Industrial Pumps and Compressors
- Aerospace Actuation Systems
- High-Rigidity Robotic Arms
