U-type seals

U-seals are sealing rings used in hydraulic and pneumatic actuators, designed to work in reciprocating motion. Their main function is to prevent leaks of working fluids and protect the system from contaminants that could cause mechanical damage. The design of U-seals allows for effective adaptation to the mating surfaces, minimizing friction and extending the life of the components.

These seals are available in various variants, tailored to work on both the piston and rod sides. Under standard conditions, they do not require backup rings, but in applications with very high pressure, additional reinforcement elements can be used to prevent seal deformation. Thanks to the use of abrasion-resistant elastomers capable of withstanding high temperatures and pressures, U-seals are suitable for construction machinery, industrial automation, and high-intensity hydraulic systems where reliability and long life are essential.

U-type seals are used in hydraulic and pneumatic cylinders, where crucial protection against leaks and contamination in reciprocating motion is required. They are applied in construction machinery (excavators, loaders, cranes), heavy industry, industrial automation, and hydraulic control systems, where the reliability of the seal influences the efficiency of the entire system. Thanks to their resistance to high pressures and wear, they ensure long lifespan of cylinders, reducing failures and the need for frequent maintenance.

U-type seals provide high sealing performance in hydraulic and pneumatic actuators, effectively preventing leaks and protecting the system from contaminants. Thanks to their optimal geometry, they minimize friction, resulting in less wear on the piston and cylinder, and longer component lifespan. They are resistant to high pressures and dynamic loads, making them suitable for demanding industrial conditions. Their use improves the efficiency of the hydraulic system, reduces the need for frequent maintenance, and lowers the risk of failures, directly leading to reduced operating costs.
