| 2RS | Double rubber contact seals on both sides | Superior contamination protection and lubricant retention |
682 2rs Bearing Structural Features & Performance Benefits
Compact Design & Precision Engineering: With a 2mm bore diameter and overall dimensions of 5mm OD × 2.3mm width, this bearing provides optimal space utilization while maintaining structural integrity through chrome steel rings and balls.
Enhanced Sealing Performance: The double rubber seals (2RS) effectively exclude contaminants while retaining lubrication, making the bearing suitable for applications where maintenance access is limited. The nitrile rubber seal material provides good chemical resistance and temperature stability.
Optimized Load Capacity: Featuring 6 precision balls with 0.8mm diameter, the bearing delivers a dynamic load rating of 32 lbf and static load rating of 9 lbf, providing reliable performance under radial loads in miniature applications.
Stainless Steel Cage: The stainless steel cage ensures proper ball spacing and guidance, contributing to smooth operation and extended service life even at the limiting speed of 85,000 rpm.
