7017 CE/P4ADBA Bearing Product Overview & Core Advantages
The 7017 CE/P4ADBA is a metric precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. This duplex back-to-back (DB) matched set delivers superior performance in handling combined radial and axial loads. Manufactured to the exacting P4A tolerance class and featuring an extra light preload (Class A), it ensures minimal runout and high positional accuracy, making it ideal for high-speed, high-precision machinery where reliability is paramount.
7017 CE/P4ADBA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7017 | Basic bearing series and size designation (85mm bore, 130mm OD, 44mm width). |
| C | Designates a 15° contact angle, optimized for high-speed operation and axial load capacity. |
| E | Indicates an optimized internal design for enhanced performance and load rating. |
| P4A | Specifies the high precision tolerance class, exceeding ABEC 7 standards for exceptional dimensional and running accuracy. |
| DB | Denotes the Duplex Back-to-Back mounting arrangement, providing high rigidity against moment loads. |
| A | Specifies the extra light preload (Class A), minimizing friction and heat generation at high speeds. |
7017 CE/P4ADBA Bearing Structural Features & Performance Benefits
- High Rigidity & Moment Load Capacity: The duplex back-to-back (DB) arrangement creates a wide, stable support system that significantly increases rigidity and effectively resists moment loads, ensuring precise shaft positioning.
- Superior Load Handling: The 15° contact angle and optimized internal geometry enable the bearing to efficiently support combined radial and axial loads simultaneously.
- High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the precision-ground chrome steel components and optimized internal design contribute to a high limiting speed of 28,000 rpm.
- Precision & Accuracy: Manufactured to P4A tolerance class with extremely tight dimensional tolerances on the bore, outside diameter, and width, this bearing guarantees smooth, quiet, and accurate operation.
- Pre-lubricated for Immediate Use: The bearing comes lubricated from the factory, ready for installation and immediate operation within its specified temperature range.
7017 CE/P4ADBA Bearing Typical Application Areas
The 7017 CE/P4ADBA is engineered for high-performance applications across various industries, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers requiring extreme precision and rigidity.
- Precision Gearboxes: Applications demanding low noise, high accuracy, and reliable power transmission.
- High-Frequency Motors and Spindles: Where minimal runout and high rotational speeds are critical.
- Medical and Laboratory Equipment: Centrifuges and imaging devices that depend on smooth, vibration-free operation.
