Step seal K 4.50 for Terex RT780

The K-type step seal is a component used within the hydraulic systems of heavy machinery to maintain pressure integrity. This seal is specifically sized at 4.50 inches to provide a precise fit for the internal components of hydraulic cylinders, such as those found in the boom, outrigger, or steering assemblies of the Terex RT780 crane. It functions by creating a seal between the piston and the cylinder wall, which prevents fluid bypass and enables the conversion of hydraulic pressure into controlled linear motion.

This component is compatible with the Terex RT780 model. The design utilizes a configuration that includes an energizing element to maintain consistent contact with the cylinder bore, ensuring the seal remains effective across varying operating pressures. By preventing internal leakage, this seal helps maintain the volumetric efficiency of the hydraulic system, which is necessary for the consistent operation of the machine's lifting and positioning functions.

In hydraulic systems, seals of this type are essential for separating pressure chambers within a cylinder. Proper installation and maintenance of these seals are required to ensure that the hydraulic system can hold loads and perform movements as intended by the machine's design specifications.
