S7017 CD/P4ADGC Bearing Product Overview & Core Advantages
The S7017 CD/P4ADGC is a precision double row angular contact ball bearing designed for applications demanding exceptional accuracy and rigidity. Engineered to the exacting P4A tolerance class, this bearing excels at simultaneously handling combined radial and axial loads from both directions. Its universal matchable (SU) design allows for flexible mounting arrangements without requiring selective assembly, simplifying installation and ensuring optimal performance. With a moderate preload (Class C) and a 15° contact angle, it delivers high running accuracy, superior stiffness, and reliable operation in high-speed environments.
S7017 CD/P4ADGC Bearing Model Code Explained, Specifications & Naming Convention
The model designation S7017 CD/P4ADGC provides detailed technical specifications:
- S7017: Basic bearing designation indicating a 85mm bore, 130mm OD, and 44mm width.
- C: Denotes a 15° contact angle.
- D: Indicates the bearing is part of a universal matchable (SU) pair.
- P4A: Specifies the ultra-precision tolerance class, exceeding ABEC 7 standards for exceptional running accuracy.
- DG: Signifies the bearing is preloaded with a moderate preload (Class C).
- C: Identifies the phenolic resin cage, which contributes to low weight, high strength, and superior performance at high speeds.
S7017 CD/P4ADGC Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design and moderate preload provide significantly increased rigidity compared to single row bearings, enabling stable support for spindles and shafts under combined loads.
- Precision & High-Speed Performance: Manufactured to P4A tolerance standards and featuring a lightweight phenolic cage, this bearing achieves smooth operation and a high limiting speed of 28,000 rpm, making it ideal for high-speed spindles.
- Optimized for Matched Sets: The Universal Matchable (SU) feature allows any two bearings to be mounted together in any combination (back-to-back, face-to-face, or tandem) to achieve the required rigidity and preload, simplifying inventory and assembly.
- Sealed & Pre-Lubricated: The bearing comes sealed and pre-lubricated with grease, offering protection from contamination and providing long-term, maintenance-free operation within a temperature range of -30°C to 110°C.
S7017 CD/P4ADGC Bearing Typical Application Areas
The S7017 CD/P4ADGC is ideally suited for high-precision, high-speed machinery, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Grinding Spindles: Internal and external grinding applications.
- High-Frequency Motors: Spindles for PCB drilling and routing.
- Medical Equipment: High-speed centrifuges and dental handpieces.
- Robotics: Precision joints and rotary actuators.
