S7017 ACD/P4ADGC Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior radial and axial stiffness, enabling stable operation under combined loads. With a 25° contact angle and optimized internal geometry, it efficiently handles significant bidirectional axial forces alongside radial loads.
High-Speed Performance: The lightweight phenolic cage minimizes centrifugal forces, contributing to the high limiting speed of 17,000 rpm. This makes it suitable for high-speed spindle applications where rotational accuracy is critical.
Precision & Longevity: Manufactured to P4A tolerance class with precise bearing dimensions (85mm bore, 130mm OD), it ensures minimal runout and vibration. The sealed construction with factory-applied grease provides contamination protection and extended service life without relubrication.
S7017 ACD/P4ADGC Bearing Typical Application Areas
- Machine Tool Spindles: High-speed machining centers, grinding spindles
- Precision Industrial Pumps & Compressors: Where combined loads and high speeds are present
- Robotic Drives & Precision Gearboxes: Requiring high rigidity and accuracy
