S685 2rs Bearing Product Overview & Core Advantages
The S685 2RS is a single row deep groove ball bearing designed for precision applications requiring reliable performance in compact spaces. This sealed bearing features stainless steel construction throughout its rings, balls, and cage, ensuring excellent corrosion resistance. Its primary advantage lies in its ability to handle radial loads efficiently while offering protection against contamination through its integrated seals. The bearing is pre-lubricated and ready for installation, making it ideal for applications demanding low maintenance and consistent operation within its specified temperature range.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| S685 | Basic bearing designation indicating metric dimensions: 5mm bore, 11mm OD, 5mm width |
| 2RS | Double rubber seals on both sides providing superior contamination protection |
S685 2rs Bearing Structural Features & Performance Benefits
- Deep Groove Geometry: Optimized raceway design enables smooth operation and efficient radial load distribution
- Full Complement Stainless Steel: All critical components (rings, balls, cage) manufactured from stainless steel for exceptional corrosion resistance and durability
- Double Rubber Seals (2RS): Nitrile rubber seals on both sides effectively exclude contaminants while retaining lubrication, extending service life
- Precision Engineering: Manufactured to ABEC1 tolerance class with MC3 radial clearance (0.002-0.013mm) ensuring consistent performance
- Optimized Ball Configuration: Eight 1.588mm diameter balls provide balanced load distribution and smooth rotational characteristics
S685 2rs Bearing Typical Application Areas
- Small Precision Motors: Ideal for miniature DC motors and stepper motors requiring reliable high-speed operation up to 40,500 rpm
- Medical Devices: Suitable for surgical instruments, dental handpieces, and diagnostic equipment where corrosion resistance and cleanliness are critical
- Office Automation: Used in printers, scanners, and copiers for precision roller and shaft support
- Instrumentation: Applications in measuring devices, optical equipment, and laboratory instruments demanding vibration-free performance
- Food Processing Equipment: Corrosion-resistant properties make it suitable for food-grade applications where washdowns are common
