Stemco was founded on March 1, 1951, by Ben Cook and Tom Davidson in St. Charles, Missouri, and originally manufactured mufflers and oil reservoirs for commercial trucks. The company moved to Longview, Texas, in 1958 to expand the company and began manufacturing new truck parts, including dual wheel adapters, hub hose carriers, drum check ...
A seal is a device or material that helps join systems, mechanisms or other materials together by preventing leakage (e.g. in a pumping system), containing pressure, or excluding contamination. The effectiveness of a seal is dependent on adhesion in the case of sealants and compression in the case of gaskets .
Indeed, many gas turbine engine seals leak by design. [4] Labyrinth seals are also found on pistons, which use them to store oil and seal against high pressure during compression and power strokes, as well as on non-rotating shafts. In these applications, it is the long and difficult path and the formation of controlled fluid vortices plus some ...
All end-face mechanical seals have rotating elements, stationary elements, and include five basic components: [1] seal ring; mating ring; secondary sealing elements; springs; Encasing; The seal ring and mating ring are sometimes referred to as the primary sealing surfaces. The primary sealing surfaces are the heart of the end-face mechanical seal.
In an internal combustion engine, a head gasket provides the seal between the engine block and cylinder head(s). Its purpose is to seal the combustion gases within the cylinders and to avoid coolant or engine oil leaking into the cylinders. [1] Leaks in the head gasket can cause poor engine running and/or overheating.
Seals are used to prevent oil leakage, control air for cooling and prevent stray air flows into turbine cavities. A series of (e.g. labyrinth) seals allow a small flow of bleed air to wash the turbine disc to extract heat and, at the same time, pressurize the turbine rim seal, to prevent hot gases entering the inner part of the engine.
The Vyrus 985 C3, an exclusive Italian motorcycle with hub-center steering, of which 24 were sold between 2004-2008 Hub-center steering in Bimota Tesi 1/D. Hub-center steering (HCS) is one of several different types of front-end suspension/steering mechanisms used in motorcycles and cargo bicycles. Hub-center steering is characterized by the ...
USS Enterprise plans, used in Star Trek III: The Search for Spock in a monitor display when the seal on Spock's living quarters is broken. In addition, the manual, along with semi-official blueprints available at the time of the Klingon and Romulan ships, was a major source for the initial designs used for Federation ships for the board game ...
