Wear ring for Terex BT4792

The wear ring, part number 226086, functions as a guide and bearing element within the front jack cylinder of the Terex BT4792 crane. It is mounted on the piston to prevent direct contact between the piston and the cylinder wall, which helps to maintain the structural integrity of the cylinder assembly during operation. By managing the clearance between these moving parts, the ring ensures smooth, consistent movement of the piston throughout the stroke.

This component is specifically sized for the front jack cylinder system on the Terex BT4792. It is manufactured by Terex to meet the original design requirements for this machine. Proper installation of this ring is necessary to support the piston and ensure the hydraulic system operates within its intended tolerances.

In hydraulic cylinders, wear rings serve to center the piston rod or piston, preventing side-loading that can damage internal seals. By absorbing the radial forces generated during cylinder extension and retraction, they protect the cylinder bore and piston surfaces from scoring and premature wear. This helps maintain the efficiency of the hydraulic seal assembly and supports the overall stability of the machine.
