Product Description

4K4390U CUP USH UPH UN NBR FKM Pu Seals Hydraulic Seals Piston Rod Seal 8H9520 


USH UPH UN NBR FKM pu seals Hydraulic Seals Piston Rod Seal
Piston 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. Leakage through the rod seal can reduce equipment performance, and also in extreme cases can cause environmental issue.

DL offers a wide range of hydraulic rod seals for both single-acting and double-acting systems.

Particular attention should be paid to pair the rod seal and the wiper for the best sealing performance. If a less aggressive rod seal is paired with an aggressive wiper, the wiper can scrape off the microscopically thin film of oil that remains on the rod in microscopic surface imperfections during the return stroke, resulting in system leakage.

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.

DL SEALLS range of pneumatic seals includes:
Pneumatic rod seals
Piston seals
Rod seal - scraper combinations
Static seals
Pneumatic scrapers
Wear rings and cushioning seals
