PSS Shaft seals

PSS shaft seals are available for propeller shafts sizes 20mm-90mm (type A) and 100mm-150mm (type B). To find and enquire about a right model for your vessel, please, use our calculator/enquiry form for PSS shaft seals.

Product Description

The PSS seal is a mechanical seal between the flat surface of the stainless steel  rotor and the stationary flange made of carbon. The stationary carbon flange is attached to the stern tube and the carbon flange is attached to the front of the bellows with hose clamps.

The stainless steel rotor:

The carbon stator:

The stainless steel rotor is used to compress the bellows before the collar is attached to the shaft with the set screws. This compression maintains contact between the stator of the PSS to compensate for the thrust of the screw.

The carbon flange is slightly larger than the shaft diameter so it rotates around the shaft. Therefore, most deviations and vibrations are  compensated.

The stainless steel collar closes the shaft with two O-rings that are sunk in the collar bore. These O-rings rotate with the shaft and stainless steel rotor, and do not wear during use.
