The best guides on hydraulic or pneumatic cylinders

Written by Marketing Digital on 05/12/2017. Posted in Estanqueidad para hidráulica y neumática.

Guides are absolutely indispensable elements in the world of hydraulics and pneumatics. They are installed in the rods and pistons of hydraulic and pneumatic cylinders, in order to allow a good guiding between the piston and the cylinder liner or between the rod and the cylinder head. The use of guides avoids damage caused by contact between metal surfaces. In addition, the guides must allow a smooth, straight movement with as little friction as possible to minimize energy losses due to friction as much as possible. For this reason, you should...

What are inflatable seals for?

Written by Marketing Digital on 01/12/2017. Posted in Estanqueidad estática.

When the customer is faced with the problem of sealing between components that move against each other at will; the easiest, safest and most effective solution is to use an inflatable gasket or pneumatic gasket. Characteristics of inflatable gaskets Inflatable seals expand with the injection of compressed air and regain their shape when the inflatable seal valve releases the compressed air. Operation is simple. Inflatable seals meet temperature ranges from -65°C to +315°C, depending on the elastomer formulation. The materials most in demand are...

Pressure seals, an excellent sealing solution

Written by Marketing Digital on 29/11/2017. Posted in Estanqueidad para equipos rotativos.

When considering a seal, a maximum pressure of up to 0.5 bar is considered. However, there are many applications where the working pressure can be much higher, as is the case with Epidor SRT pressure seals. In general, the pressure load (P) and the peripheral speed (v) will determine the range of use of the seals. When the respective limit values are exceeded, wear will be premature and lead to a reduction in seal life, unless a pressure seal is used. Conventional oil seals are designed...

Epidor SRT high performance polyurethane seals

High performance polyurethane gaskets

Written by Marketing Digital on 22/11/2017. Posted in Estanqueidad para hidráulica y neumática.

Hydraulic systems often operate under severe and even extreme conditions. Sealing materials must ensure reliable operation regardless of the conditions in which they operate, including climate aspects such as relative humidity in a tropical environment with regard to the hydrolysis of polyurethane seals and gaskets. Even seals that meet these requirements, it is common for them to wear out due to sudden changes in temperature or inadequate maintenance. A particular case is the rental of heavy machinery, where...
