Page 2 of 2 Gland MachiningAn optimum finished surface of 8 to 16 RMS will help to control friction. Finishes below 5 RMS will not hold the lubricant because it eliminates micropores. Groove WidthBy increasing the groove width, the seal will be allowed more room to expand perpendicular to the compressive force. MaterialMaterials vary in their friction characteristics. For example, Teflon has a very low coefficient of friction. For more complete information on individual materials look in Section 6. PressureDecrease system pressure to reduce the amount of running friction. |
