Description

U cup UN is used in a wide range of hydraulic cylinders. These seals have a symmetrical configuration of the sealing lips and are mainly used in single acting or double acting standard hydraulic cylinders, particularly for mobile hydraulics under rough operating conditions.

UN hydraulic seals is a lip seal that can be used for piston and rod seals because of the equal height of the two seal lips. The piston rod seal is the most critical seal on any type of fluid power plant, preventing fluid from leaking out of the cylinder to the outside.

Leakage through the rod seal can degrade equipment performance and, in extreme cases, environmental problems. Combined for engineering, the range of automatic hydraulic equipment for the sealing of pistons and piston rods in reciprocating hydraulic cylinders. It is used in a wide range of hydraulic cylinders. UN is a lip seal that can be used for piston and rod seals because of the equal height of the two seal lips.
