The Type SYBM4 is the leading seal of choice for demanding of high  temperature applications. Available in either 17-4PH, AM350 or Alloy 718, its high-strength design provides maximum reliability. The stationary bellows design accommodates high shaft-to-seal-chamber misalignment.

Unlike rotating seals that must flex on every revolution to accommodate shaft-to-seal-chamber misalignment, the stationary SYBM4 adapts to this condition by flexing only once during installation. This reduces seal movement, resulting in increased seal life.
