Lasdrop Seals, PSS Shaft Seals, Manecraft Seals and Tides Marine SureSeal System.
Marine shaft seals are devices that prevent water from entering the boat through the propeller shaft. They are designed to be durable, reliable, and easy to maintain. There are different types of marine shaft seals, such as stuffing boxes, face seals, and lip seals, each with their own advantages and disadvantages.
Stuffing boxes are the traditional type of shaft seals, which use flax packing and a gland nut to create a seal around the shaft. They require periodic adjustment and lubrication, and allow a small amount of water to drip into the bilge.
Face seals are the most popular type of shaft seals, which use a rotating collar and a stationary flange to create a seal between two flat surfaces. They are self-aligning, watertight, and can compensate for shaft movement and vibration.
They do not need regular maintenance, but they require a hose to vent the air and excess water.
Lip seals are the newest type of shaft seals, which use a rubber lip that presses against the shaft to create a seal. They are simple, compact, and inexpensive, but they have a shorter lifespan and can wear out the shaft if not properly aligned. They also need a water injection system to keep them cool and lubricated.
If you are looking for a marine shaft seal for your boat, you should consider the size, shape, and condition of your shaft, the type and speed of your boat, and your budget and preferences. Give us a call and we can help you find the best shaft seal for your boat.
