Metal Bellow Seal (CAI-109)

TYPE CAI-109 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 400OC. Shrunk fit seal face design minimize face distortion restricting leakage and wear rate to very low level under a wide range of condition.
