SF697 2rs Bearing Product Overview & Core Advantages
The SF697 2RS is a single row deep groove ball bearing designed for high-performance applications requiring reliable operation in compact spaces. Engineered with stainless steel rings and balls, it offers excellent corrosion resistance. Its key advantage lies in its sealed design (2RS), which provides robust protection against contaminants and retains lubrication, making it suitable for applications demanding long service life with minimal maintenance. This bearing is optimized to handle primarily radial loads efficiently.
SF697 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| 2RS | Indicates the bearing is fitted with two rubber contact seals (one on each side). This provides superior sealing effectiveness compared to non-contact shields, protecting against dust, moisture, and other contaminants. |
SF697 2rs Bearing Structural Features & Performance Benefits
- Robust Sealing & Contamination Resistance: The dual Nitrile Rubber (NBR) contact seals (2RS) effectively prevent the ingress of contaminants and the egress of lubricant, significantly enhancing bearing life in harsh environments.
- Corrosion Resistance: Constructed entirely from stainless steel (rings, balls, and cage), this bearing is ideal for applications exposed to moisture, chemicals, or washdowns, such as in food processing or medical equipment.
- High-Speed Capability: The stainless steel cage and optimized internal geometry contribute to stable operation at high rotational speeds, with a limiting speed of 32,400 rpm.
- Precision & Reliability: Manufactured to ABEC1 tolerance class, it ensures consistent performance and smooth operation, suitable for a wide range of industrial applications.
- Compact & Lightweight Design: With a compact cross-section (17mm OD, 5mm width) and a low weight of 5.54g, it is perfect for space-constrained and weight-sensitive designs.
SF697 2rs Bearing Typical Application Areas
- Small Electric Motors and Gear Motors
- Precision Instruments and Medical Devices
- Office Automation Equipment (e.g., Printers, Scanners)
- Food and Beverage Processing Machinery
- Robotics and Small Actuators
- Computer Cooling Fans and Spindles
