U Seals

U seal is a single acting piston-rod seal and designed to have symmetrical lips in order to be used both for rod and piston applications. It is the most critical seal on any type of fluid power equipment preventing leakage of fluid from within the cylinder to the outside. Leakage through the rod seal can reduce equipment performance, and also in extreme cases can cause environmental issue.

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.

Technical Data

• Temperature: -35~+100
• Speed: 0.5m/s
• Media: Hydraulic oils (mineral oil-based)

Advantages

• Superior static and dynamic sealing effect.
• Wide range of dimensions.
• Easy assembly into closed grooves.
• Simple groove design.
• Economical sealing solution.

Application
Construction machinery, fork lift trucks, injection moulding machines, gricultural machinery, loading platforms and standard cylinders.

Installation
This seal fits easily in closed grooves as per the sizes. You use special tools during installation. But,the assembly tools must be of soft material and have no sharp edges. Otherwise, the seal might gets damaged. Before installation the wiper must be oiled with system oil.
