Shaft speed and lip materials
SHAFT SPEEDS AND LIP MATERIALS
An important consideration when selecting the lip material is the shaft speed (measured in rotations per minute), circumferential speed (measured in feet per second), and shaft diameter (measured in inches). These conditions determine whether or not a given elastomer will operate properly.
The graph below offers general guidelines for determining the compatibility of silicone, fluorocarbon, polyacrylate and nitrile with specific shaft and circumferential speed. For more information, please contact with us.
