Wear ring for Terex BT4792

The wear ring, part number 218901, functions as a guide for the piston within the front jack cylinder assembly of the Terex BT4792 crane. By maintaining the position of the piston, it prevents direct metal-to-metal contact between the piston and the inner wall of the cylinder. This component is specifically engineered for the front jack cylinder system to ensure smooth and consistent movement during the leveling and stabilization of the crane.

This component is compatible with the Terex BT4792 model. It is designed to fit the dimensions and specifications required for the front jack cylinder assembly to maintain proper operational clearance.

In hydraulic cylinders, wear rings are used to support the piston and rod under lateral loads. They provide a bearing surface that allows the piston to travel along the cylinder bore without damaging the sealing surfaces or the cylinder walls. Proper installation and regular inspection of these rings are necessary to prevent internal bypass and to maintain the hydraulic efficiency of the cylinder during lifting operations.
