Through rod cylinder is an important kind of pneumatic cylinder. It is made up of seamless pipes which are honed to micro finish surface to give long life to seals. Rod of cylinders is made of EN8 which are ground and hard chrome plated. Different types of seals are used depending upon applications. Materials of seals are polyurethane, PTFC, NBR etc.
Besides, through rod cylinder is a mechanical device used to impart a force from a fluid, such as air. In order to fulfill their function, it metes a force by converting the potential energy of compressed gas into kinetic energy. This is carried out by the compressed gas being able to expand, without external energy input, which itself occurs due to the pressure gradient established by the compressed gas being at a greater pressure than the atmospheric pressure. This air expansion forces a piston to move in the desired direction. The piston is a disc or cylinder, and the piston rod transfers the force it develops to the object to be moved.
Finally, through rod cylinder is mainly used for earthmoving construction machinery, mines, general purpose industries use, hydraulic machinery and equipment etc.
