KEMEL Stern Tube Seals: What Makes Them Environmentally Friendly?
Blog | February 21st, 2020Our oceans have so much traffic on them today with fishing vessels, oil tankers, cruise ships and other types of vessels traversing from destination to another. In fact, there is such a high amount of traffic that it is becoming more difficult to keep the water from being polluted, especially if the vessels are not […]
Stern Tube Bearing Failures: What are the Possible Causes?
Blog | November 4th, 2019A stern tube bearing failure is never viewed as a trivial issue. Apart from anything else, that seal is a route to the interior of a boat’s hull. If seal integrity goes, the inevitable loss of hull fidelity will likely adversely affect the rest of the boat. Keep that thought in mind as you learn […]
Differences Between Oil-Lubricated and Water-Lubricated Stern Tube Bearings
Blog | July 5th, 2019Without wishing to state the obvious, water-lubricated stern tubes use H2O as a shaft lubrication fluid. For oil-lubricated solutions, a greasy fluid provides a slippery shaft greasing feature. These are the clear-cut differences, as plainly assigned by their technical labels. So far so good, the principal difference is right there, right in the fluid medium. […]
Understanding Stern Tube System in Marine Vessel Operations
Blog | June 4th, 2019Stern tube systems are classified as powertrain intermediaries in a marine vessel’s propulsion mechanism. First comes the propeller, then there’s the sealed stern tube assembly, which links the propeller shaft to a ship’s main engine. In effect, there’s a hole in the hull for a ship’s drive shaft to reach into the surrounding water. The […]
Stern Tube Integrity Test During Dry Dock: How Is It Done?
Blog | February 14th, 2019Without making a habit of stating the obvious, let’s just say that a stern tube integrity test isn’t a job that’s done at sea. That tube is located way below the waterline. A boat’s propeller shaft passes through the shaft, so it’s about as near to the bottom of a vessel’s hull as you can […]
