7034 CD/P4A Bearing Product Overview & Core Advantages
The 7034 CD/P4A is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Engineered to a P4 (ABEC-7) tolerance class, it is ideal for high-speed spindles and other precision machinery. Its key advantage lies in its ability to accommodate combined loads—significant radial loads and substantial thrust loads in one direction—thanks to its specific 15° contact angle. The phenolic resin cage and preloaded design contribute to its high-speed capability and operational stability, making it a reliable choice for demanding industrial environments.
7034 CD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7034 | Basic bearing designation indicating a metric series with a 170mm bore, 260mm OD, and 42mm width. |
| CD | Indicates a specific contact angle of 15° and a specific internal design optimized for high rigidity. |
| P4 | Denotes the tolerance class P4 (ABEC-7), signifying very high dimensional and running accuracy. |
| A | Signifies that the bearing is supplied with a preload to minimize axial and radial play, enhancing system stiffness. |
7034 CD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: Manufactured to P4 tolerance standards with a phenolic resin cage, this bearing ensures minimal vibration and precise shaft guidance, critical for high-speed applications.
- Superior Load Capacity: The 15° contact angle design enables the bearing to effectively support high combined radial and axial loads (Dynamic: 47,700 lbf, Static: 55,125 lbf).
- Optimized High-Speed Performance: The lightweight and robust phenolic cage, combined with the optimized internal geometry, allows for a high limiting speed of 8,000 rpm.
- Preloaded for Stability: The "A" suffix indicates the bearing is preloaded, which increases system rigidity, reduces noise, and improves positional accuracy under operational loads.
7034 CD/P4A Bearing Typical Application Areas
This precision bearing is ideally suited for high-performance machinery where accuracy and speed are paramount. Key application fields include:
- Machine Tool Spindles for milling, grinding, and turning centers
- High-Frequency Motors and precision spindles
- Industrial Pumps and compressors
- Precision Gearboxes and robotics
