U2 type seals
Sealing rings of type U2, made of high-quality materials, are widely used for sealing joints in reciprocating motion under higher dynamic working conditions compared to U1 sealing rings. Type U2 does not require backup rings. The lip sealing pressure and their shape, strength, self-increase due to compression. Thanks to the appropriate shape and precise construction, there is no need to worry about protecting and lubricating the gap even at high pressures.
What are U2 seals and what are they used for?
U2 seals are symmetrical sealing rings used in hydraulic and pneumatic cylinders, designed for reciprocating motion. Their main function is to ensure tightness in piston and rod systems, preventing leaks of working fluids and contamination. Thanks to their double-sided design, they can be used on both the piston and rod sides, making them a versatile solution for various industrial applications.
Under normal conditions, U2 seals do not require backup rings, but in cases of very high pressures or larger installation clearances, their use may be recommended to prevent deformation and extend the seal's lifespan. Made of wear-resistant elastomers, they are highly resistant to friction and intensive use, making them a reliable solution in construction machinery, industrial equipment, and automation systems. They provide long life for hydraulic systems, reducing the risk of failure and the need for frequent maintenance.
Application of type U2 seals
U2 type seals are used in hydraulic and pneumatic actuators, where sealing in reciprocating motion is crucial. They are applied on both the piston and rod sides, ensuring effective protection against leaks and contaminants. They are utilized in construction machinery (excavators, loaders, cranes), industrial hydraulic presses, automation systems, and motion control systems. Thanks to their resistance to high pressures and friction, they guarantee long component lifespan and stable system operation in demanding operating conditions.
Benefits of using U2 type sealing
U2 type seals ensure high tightness in hydraulic and pneumatic actuators, effectively preventing leaks and the ingress of contaminants. Thanks to their symmetrical construction, they can be used on both the piston and rod sides, increasing their versatility. Low friction reduces the wear of cooperating elements, extending their lifespan and reducing operating costs. U2 seals are resistant to high pressures and intense operation, making them a reliable solution in construction machinery, industrial automation, and hydraulic systems requiring stable operation and long-lasting durability.
