PSS 50mm Shaft / 2 3/4in Tub

The PSS 50mm Shaft / 2 3/4in Tub is a premium shaft seal designed for marine applications, offering unparalleled performance and reliability. As the number one selling marine mechanical seal worldwide, the PSS Shaft Seal is recognized for its exceptional quality and is installed as standard equipment by many reputable boat builders and yards. This seal is also the premier retrofit option on the global market, making it a versatile choice for both new installations and replacements.

Product Specifications and Technical Details

The PSS Shaft Seal is engineered to fit shaft sizes ranging from 3/4" (20mm) to 6" (150mm), ensuring compatibility with a wide range of vessels. This specific model is designed for a 50mm shaft and a stern tube diameter of 2.750" to 2.875". The seal features a mechanical face seal created between the rotating stainless steel rotor and the stationary carbon flange. The carbon flange is attached to the vessel's stern tube with hose clamps, while the stainless steel rotor is secured to the shaft. This design eliminates the need for constant adjustment and maintenance, as seen with traditional packing type glands. The carbon flange is bored larger than the shaft diameter, allowing it to "float" around the shaft and compensate for misalignment and vibration issues.

The PSS Shaft Seal is an essential component for any marine vessel, offering numerous benefits. Its 100% watertight design helps to eliminate water in the bilge, ensuring a dry and safe environment below deck. The seal also reduces wear on the propeller shaft, extending its lifespan and improving overall efficiency. With its easy retrofit capability, the PSS Shaft Seal is a practical solution for boat owners looking to upgrade their existing seals or for new installations. Whether you're a professional boat builder or a recreational boater, the PSS Shaft Seal provides the reliability and performance you need to keep your vessel running smoothly.
