The stationary carbon flange is attached to the vessels stern tube with hose clamps and the carbon flange is attached to the front side of the bellows with hose clamps. The stainless steel rotor is fit on the shaft in front of the carbon flange. The stainless steel rotor is used to compress the bellows before the collar is secured to the shaft with set-screws. This compression (pre-load) maintains contact between the faces and allows the PSS to compensate for the thrust from the propeller. The carbon flange is bored larger than the shaft diameter allowing it to \"float\" around the shaft and thus compensate for most misalignment and vibration problems. The stainless steel collar is sealed to the shaft by two o-rings that are recessed into the bore of the collar. These o-rings rotate with the shaft and stainless steel rotor and do not experience wear during operation.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e**As with any rubber hose below waterline, the PSS bellows must be inspected on a regular basis for any sign of wear, aging or chemical deterioration.

The carbon graphite stator will polish the face of the rotor during the first few minutes of operation. The stainless steel rotor should not need to be replaced under normal operating conditions.

The blanks are then baked, machined, and lapped. The face of our carbon is finished to a flatness of 4 helium light bands (measured .000044\" of variation over the entire lapped surface). The grade of carbon used in the PSS has an operating temperature of over 500° Fahrenheit (+260° Celsius) and cannot melt if the seal runs dry, unlike a rubber lip seal or plastic face seal. The high density of the carbon greatly increases its longevity and wear resistance. Several commercial vessels have recorded over 40,000 (over 4-1\/2 years of continuous operation) engine hours on the same, original components.
