IDI U CUP PU  cylinder piston rod main seal

U cup Hydraulic Rod Piston PU Seal Polyurethane (PU) is a special material that offers the resilience of rubber combined with the toughness and durableness. It allows people to substitute rubber, plastic and metal with PU. Polyurethane can reduce factory maintenance and OEM product cost. Polyurethane has better abrasion and tear resistance than rubbers, and offering higher load bearing capacity. Compared PU with plastic, polyurethane not only offers excellent impact resistance, but also offers excellent wear resistant and high tensile strength. Polyurethane have subsituted metals in sleeve bearings, wear plates, conveyor rollers, rollers and various other parts, with benefits such as weight reduction, noise abatement and wear improvements.

Types of Piston rod seals

Rod & Piston seals are equal lip-seal which can be used for both piston seal and rod seal.

They're also the most critical seals on any type of fluid power equipment preventing leakage of fluid from within the cylinder to the outside. Leakage through the rod or piston seal can reduce equipment performance, and also in extreme cases can cause environmental issues.
