S687 2rs Bearing Product Overview & Core Advantages
The S687 2RS is a metric miniature deep groove ball bearing engineered for precision applications requiring compact design and reliable performance. Constructed entirely from stainless steel (rings, balls, and cage) for excellent corrosion resistance, this sealed single row bearing is pre-lubricated and shielded to exclude contaminants, making it ideal for applications demanding low maintenance and long service life. Its design is optimized to handle primarily radial loads efficiently within a compact envelope, offering a robust solution for high-speed operations.
Model Code Breakdown
| Model Segment | Technical Meaning |
|---|---|
| S687 | The basic bearing designation, indicating a metric series with a 7 mm bore, 14 mm outside diameter, and 5 mm width. |
| 2RS | Denotes that the bearing is equipped with two (2) rubber seals (RS), one on each side. This provides effective protection against contamination and retains lubricant, supporting the bearing's maintenance-free characteristic. |
S687 2rs Bearing Structural Features & Performance Benefits
- Robust Stainless Steel Construction: All critical components—inner ring, outer ring, balls, and cage—are manufactured from stainless steel. This provides superior corrosion resistance, making the bearing suitable for harsh environments and applications requiring washdown or exposure to moisture.
- Effective Sealing with Low Torque: The 2RS nitrile rubber seals effectively shield the internal components from dust, dirt, and moisture while helping to retain the factory-applied lubricant. This design contributes to a long, maintenance-free service life.
- Optimized for High-Speed Operation: The combination of a stainless steel cage, nine precision balls, and a MC3 radial internal clearance allows for smooth operation and a high limiting speed of 36,000 rpm.
- Precision and Reliability: Manufactured to ABEC1 tolerance class, this bearing ensures consistent running accuracy and low noise, which is critical for sensitive precision instruments and small machinery.
S687 2rs Bearing Typical Application Areas
- Small Electric Motors and Gear Motors
- Precision Instruments and Optical Devices
- Medical and Dental Equipment
- Office Automation Equipment (e.g., printers, scanners)
- Radio Control Models and Drones
- Small Pumps and Fans
