For construction machinery, hydraulic cylinders require various seals to ensure long service life and reliability. These seals prevent fluid leakage and maintain proper cylinder function under different pressures.
NAK provides piston, rod, wiper seals, wear rings, etc., made from rubber, polyurethane, PTFE, nylon, and other materials for diverse hydraulic conditions.

Pin connections link cylinders to components, and NAK Pin Dust Seals are specially designed to retain lubricant, block contaminants, reduce wear, and lower torque.
