The hydraulic inboard cylinder type CL.0-158 is part of the brass series with side fixing and tie rods.
The cylinder tube is made of brass, a material which has higher resistance to pressure than aluminium.
The tie rods are made of stainless steel.
To facilitate the bleeding of air, inclined bleed screws are installed on top of the cylinder heads.
The piston rod is made of stainless steel, chromed and rectified; the chromium plating in a protected environment guaranties a high quality plating, and an excellent protection against the marine corrosion, combined with a very smooth surface guaranties a long endurance of the seals.
The chromium helps to eliminate at least 30% of the friction caused by the use of seals and its hardness protects the piston rod from accidental scratches which could damage the seals.
The support is made of bronze.
