7017 CDGA/P4A Bearing Product Overview & Core Advantages
The 7017 CDGA/P4A is a single-row angular contact ball bearing designed for high-precision applications demanding exceptional rotational accuracy and rigidity. Manufactured to P4A tolerance class, this bearing delivers superior dimensional stability and running accuracy. Its 15° contact angle is optimized to handle significant combined loads (radial and axial) simultaneously. The bearing comes pre-lubricated and is part of a Universal Matchable (SU) set, allowing for precise preload control when mounted with a matched pair, making it ideal for high-speed spindles and other critical machinery.
7017 CDGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7017 | Basic bearing series; 85 mm bore, 130 mm OD, 22 mm width. |
| C | 15° contact angle. |
| DG | Universal Matchable bearing. Two bearings can be universally matched (SU) in a "back-to-back" (DB) or "face-to-face" (DF) arrangement. |
| A | Extra light preload class. |
| P4A | High precision tolerance class, offering extremely tight dimensional and running accuracy tolerances. |
7017 CDGA/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row design with a 15° contact angle provides excellent rigidity and is engineered to support high combined radial and axial loads.
- Superior Precision: Manufactured to P4A tolerance class with very tight bore, outer diameter, and width tolerances, ensuring minimal runout and vibration for ultra-precise applications.
- Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the pre-lubrication and optimized internal geometry contribute to a high limiting speed of 28,000 rpm.
- Universal Matching Capability (SU): As a Universal Matchable bearing, two 7017 CDGA/P4A bearings can be universally paired to form a pre-loaded set (DB or DF), simplifying assembly and ensuring consistent, high-precision performance.
7017 CDGA/P4A Bearing Typical Application Areas
This precision bearing is ideally suited for demanding applications where high speed, high rigidity, and exceptional accuracy are paramount. Key industries and machinery include:
- Machine Tool Spindles (High-speed milling, grinding)
- Precision Grinding Spindles
- High-Frequency Motors
- Medical Equipment (e.g., Dental handpieces, Centrifuges)
- Aerospace & Defense Systems
