Excavator Seal Kit Describe
DHS Wiper Seal has a double lip seal with a dust lip and an oil seal lip. Its structure makes it excellent in dust resistance and less oil leakage. In addition, The DH/DHS type double lip wiper prevents the entry of dust, dirt, sand and metal chips. Mainly used in hydraulic cylinders and cylinders,
The axial movement of the hoist and the guide rod. DHS Wiper Seal is to do reciprocating piston movement.
Wiper seal is used on the hydraulic-pneumatic piston rod to remove dust from the external surface of the piston cylinder and prevent sand, water, and contaminants from entering the sealed cylinder.
At present, most of the practical wiper seal rings are made of rubber materials, which are characterized by dry friction. In this way, rubber materials are required to have particularly good abrasion resistance and low compression permanent deformation performance.
Features
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.
Excellent durability and flexibility in using.
Excellent in resistance against heat,oil and wear.
Show stable in high speed rotation.
Resistant to heat, oil, fatigue, aging and friction due to excellent and special frame .
Large power, high speed, long service life, small distortion, less space occupy
