The V-seals are intended for the face seal, they make it possible to protect external pollutions with a weak friction force.

We offer 4 profiles to suit all applications (VA, VS, VL, and VE) from Ø 2.7 to Ø 2020.

To reduce the coefficient of friction or to provide mounting assistance on our V-seals, it is possible to apply one of the high-performance surface treatments developed by us.

Details Of a Standard System Scope Of Cuplock Scaffolding

The need for system scaffolding in the construction industry to carry out demolition, maintenance and repair work is obvious. One of the best staging structures used in Australia is the Cuplock System, which is based on securing nodes with two cups instead of wedges, nuts and bolts. It provides a fast, multiple and simplified system of start-up projects related to this field of work. It offers a quick solution to ensure up to four horizontals at a time through a reliable top cup that makes the joint firm and rigid. This type of structure is easy to lift and disassemble, leaves no loose ends, requires minimal maintenance and does not use components such as nuts, bolts and wedges. It is better for access or formwork support and has a high load capacity despite being quite light. The varied components of the Cuplock system scaffolding are listed below: Standard / Vertical Cuplock It has cup joints at regular distances; The captive moving upper cups are suitable to face the ...

History of telecommunications

The history of telecommunications, after the use of primitive means, begins with the first organized postal services, the development of the telegraph, telephone, wireless and digital communications. This is undoubtedly one of the areas where technology has evolved the fastest. Origin of telecommunications:  Telecom Tower The earliest telecommunication processes were the smoke signals used by Native American peoples in North and South America, and the drums used by the peoples of Africa, New Guinea, and South America. These signals made it possible to transmit sometimes complex information. The Yagans, for example, were using smoke signals to indicate beached whales, so the majority can take the meat from the carcass before it decomposes. Perhaps they were using these signals for other purposes, so it is possible that Fernand de Magellan saw one of these fires when he crossed Patagonia, which inspired the name of Tierra del Fuego. Transmission Tower The ancient...

Fundamentals of the fabrics

Fundamentals of the fabric basically, there are three types of fabrics on the market today; these are natural mixtures, synthetic (made by man) or fabrics. Fabric blends are fabrics where natural and synthetic fibers are used to make a type of fabric. Natural fibers are derived from plants or animals; some of the animals used are sheep, goats, alpacas, rabbits and the silkworm, which is used to make fine silk. Fabric Interlock Some of the plants used are bamboo, cotton, linen, hemp, and even pineapple leaves are used. Some of the natural fabrics are wool, silk, cotton, linen and hemp. Synthetic fibers are manufactured by a chemical process where chemicals are forced through small holes called rows. Some of the fabrics produced from these fibers are polyester, nylon, acetate and spandex. When natural and synthetic fibers are used together to create fabrics, many different fabrics can be created, because each fiber acts differently and has its own qualities. When wool and cotton...
