7017 CD/P4ADGA Bearing Product Overview & Core Advantages
The 7017 CD/P4ADGA is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Manufactured to P4A tolerance class, this bearing is engineered to handle combined loads efficiently, offering superior performance in high-speed and high-precision environments. Its universal matchable (SU) design allows for flexible mounting arrangements in pairs, simplifying installation and ensuring optimal preload for maximum system stiffness and minimal runout.
7017 CD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
The model number 7017 CD/P4ADGA provides detailed technical specifications:
- 7017: Basic designation indicating a metric series bearing with 85mm bore, 130mm OD, and 44mm width.
- C: Denotes a 15° contact angle, optimized for high-speed applications and combined radial and axial loads.
- D: Indicates the bearing is supplied as part of a universally matchable pair (SU).
- P4A: Specifies the tolerance class, indicating very high precision for inner and outer ring runouts and dimensions.
- DGA: Signifies a phenolic (polyamide) cage, extra light preload (Class A), and a standard open design without seals.
7017 CD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The angular contact design with a 15° contact angle and P4A tolerance class provides exceptional rotational accuracy and system stiffness, critical for machine tool spindles and precision equipment.
- Superior Load Capacity: Engineered to support significant combined radial and axial loads, with a dynamic load rating of 24,975 lbf and a static load rating of 29,025 lbf.
- Optimized High-Speed Performance: The lightweight phenolic cage and optimized internal geometry contribute to a high limiting speed of 28,000 rpm, reducing centrifugal forces and operational temperatures.
- Universal Matching Capability: Designed as a universally matchable (SU) set, these bearings can be arranged in back-to-back, face-to-face, or tandem configurations to suit various load and rigidity requirements without selective mounting.
- Durable Construction: Manufactured from chrome steel for both rings and balls, ensuring high durability, wear resistance, and a long operational life under demanding conditions.
7017 CD/P4ADGA Bearing Typical Application Areas
This precision angular contact bearing is ideally suited for:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers requiring extreme accuracy and rigidity.
- Precision Industrial Pumps & Compressors: Applications where reliable performance under combined loads is essential.
- High-Speed Motors & Robotic Drives: Providing smooth operation and precise positioning.
- Aerospace & Defense Systems: Gyroscopes, radar equipment, and other critical high-precision mechanisms.
- Medical Equipment: CT scanners and dental handpieces demanding quiet, high-speed, and reliable bearing performance.
