SF692 2rs Bearing Product Overview & Core Advantages
The SF692 2RS is a metric miniature ball bearing designed for precision applications requiring compact dimensions and reliable performance. Featuring a single row construction with integral rubber seals (2RS), this bearing provides effective contamination protection while maintaining smooth operation. Manufactured entirely from stainless steel components, it offers excellent corrosion resistance and is suitable for applications demanding high cleanliness standards. The bearing's flanged design enables simplified mounting and axial location, while its ABEC1 precision class ensures consistent performance in various mechanical systems.
Model Code Detailed Breakdown
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| SF692 | Basic bearing designation with 2mm bore, 6mm OD | Compact bearing dimensions for space-constrained applications |
| 2RS | Double rubber contact seals on both sides | Enhanced contamination protection and lubricant retention |
SF692 2rs Bearing Structural Features & Performance Benefits
Compact Radial Design: The single row ball bearing configuration provides optimal radial load capacity within minimal axial space, making it ideal for miniature applications where dimensional constraints are critical.
Enhanced Sealing Performance: The double rubber seals (2RS) create effective barriers against contaminants while maintaining low friction operation, extending service life in challenging environments.
Stainless Steel Construction: All critical components including rings, balls, and cage are manufactured from stainless steel, ensuring excellent corrosion resistance and compatibility with various operating conditions within the temperature range of -30°C to 110°C.
Flanged Outer Ring: The integrated flange (7.5mm OD) simplifies mounting procedures and provides positive axial location, reducing assembly time and improving positional accuracy.
Precision Engineering: With ABEC1 tolerance class and controlled radial internal clearance (MC3: 0.002-0.013mm), the bearing delivers consistent performance and smooth operation across its limiting speed of 67,500 rpm.
