S7017 ACE/P4A Bearing Product Overview & Core Advantages
The S7017 ACE/P4A is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. This single-row bearing features a 25° contact angle and is supplied with a preload, making it ideally suited for supporting combined loads where high axial and radial stiffness are critical. Manufactured to the stringent P4 (ABEC-7) tolerance class, it ensures minimal runout and vibration, delivering superior performance in high-speed, high-precision machinery. Its sealed and pre-lubricated design offers reliable, long-term operation with minimal maintenance.
Model Code Breakdown
The S7017 ACE/P4A model designation provides detailed technical specifications:
- S7017: Denotes the bearing series and size (85mm bore, 130mm OD, 22mm width).
- ACE: Indicates a 25° contact angle and that the bearing is supplied with a preload for enhanced rigidity.
- P4A: Specifies the tolerance class P4 (ABEC-7), representing very high precision levels for critical applications.
S7017 ACE/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The 25° contact angle and application of preload provide superior axial and radial stiffness, minimizing deflection under load for exceptional positional accuracy.
- Optimized Load Capacity: Engineered to handle significant combined radial and axial loads simultaneously, making it ideal for complex loading conditions.
- High-Speed Capability: The lightweight, durable phenolic resin cage ensures stable operation and guides the balls effectively, contributing to the high limiting speed of 13,000 rpm.
- Sealed and Lubricated for Longevity: The sealed design protects against contamination, while the factory-applied lubrication ensures consistent performance across the specified temperature range (-30°C to 110°C), resulting in a long service life with minimal maintenance.
