Polyurethane（PU）Oil Seal

Product Description

PU Dust Hydraulic Wiper Oil Seal DH/DHS Hydraulic Cylinder Seals for Hydraulic Polyurethane Applications.

Product Description	Polyurethane Seal (Polyurethane Seal) is a type of seal made of polyurethane material that is primarily used to prevent the leakage of oil, grease, and other liquids. It includes many advantages: High wear resistance: polyurethane oil seal has excellent wear resistance, which can effectively resist the wear in high-speed rotation or reciprocating motion, and extend the service life. Chemical resistance: Polyurethane has good resistance to many oils, solvents and chemicals and can prevent the oil seal material from being corroded. Wide operating temperature range: Polyurethane oil seals can maintain good sealing performance in low temperatures to -40°C (-40°F) and high temperatures to 120°C (248°F). High elasticity: Polyurethane materials have good elasticity and can be adapted to seal surfaces of various shapes and sizes, ensuring a tight fit. High strength: Polyurethane oil seal has high tensile strength and tear strength, can withstand high pressure and impact. Good aging resistance: polyurethane oil seal can maintain its performance after a long time of use and is not easy to age. Low coefficient of friction: The polyurethane oil seal has a low coefficient of friction, reducing friction with the shaft or sealing surface and reducing energy consumption. Customization: Polyurethane oil seals can be customized according to the specific application requirements of hardness, size and shape to adapt to different working conditions. Cost savings: While the initial cost may be higher than conventional rubber oil seals, the longer service life and lower maintenance costs of polyurethane oil seals generally make them more cost-effective. Environmental adaptability: Polyurethane oil seal can maintain good sealing effect under various environmental conditions, such as humidity, dust and vibration. Polyurethane oil seals are widely used in automotive, aerospace, industrial machinery, hydraulic and pneumatic systems, mining equipment, agricultural machinery and other fields to provide efficient and reliable sealing solutions.
