How to Choose the Right Gears & Gear Drives
When selecting gear and shaft seals, the primary considerations are shaft diameter, housing dimensions, and operating conditions. Material selection is crucial - NBR offers good oil resistance and temperature range up to 100°C, while FKM handles higher temperatures up to 200°C and provides superior chemical resistance. Verify shaft surface finish requirements (typically 0.2-0.8 μm Ra) and running speed limitations for optimal seal performance.
Seal design features impact performance and longevity. TC-type (double lip) seals provide better protection against contamination compared to single lip designs. Metal-reinforced skeletons offer improved rigidity and installation stability. Consider installation direction and whether spring-loaded designs are needed for your application. Housing bore tolerances and shaft runout specifications must meet manufacturer recommendations.
Application environment dictates material compatibility and design requirements. High-speed applications may require special lip designs or materials. Consider pressure differential across the seal, chemical exposure, and temperature cycling. Many seals conform to DIN 3760 or ISO 6194 standards for dimensional consistency. Proper installation tools and lubricants are essential for achieving maximum service life.
