| Type VMB - 50G seals specially designed for high temperature application and suitable for high start-up toque since the bellows unit is independent of torque transmission. Grafoil is used as a secondary member having excellent temperature range upto 4000C. Shrunk fit seal face design minimize face distortion restricting leakage and wear rate to very low level under a wide range of condition. |
