Product description: Piston rod seals 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.
Hydraulic cylinder seal pu seals-piston&rod seal
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.
Hydraulic cylinder seal pu seals- rod seal
The rod seal is the most critical seal on any type of fluid power equipment preventing leakage of fluid from within the cylinder to the outside.The rod seal has to meet the most demanding requirements and in addition to normal wear and aging, a rod seal is directly affected by changes on the rod surface such as temperature extremes. Leakage through the rod seal can reduce equipment performance, and also in extreme cases can cause environmental issues and therefore it is vitally important to choose the correct rod seal type and design to suit a particular application.
Hydraulic cylinder seal pu seals- Piston seal
Piston Seals or Piston Rings are used in hydraulic cylinders for fluid sealing. They are internal to the cylinder head and seal against the cylinder bore, preventing fluid from flowing across the cylinder head.
