Bushing for Terex BT4792

The bushing 223268 is a component installed within the topping cylinder assembly of the Terex BT4792 crane. Its primary function is to provide a bearing surface between moving parts, such as pins and the cylinder body, to allow for controlled articulation of the crane boom. By maintaining the correct clearance between these mechanical elements, the bushing assists in the smooth operation of the hydraulic cylinder during lifting and positioning tasks.

This part is specifically engineered for fitment in the Terex BT4792 model. It is designed to operate within the specific tolerances required by the topping cylinder system to ensure mechanical alignment and to manage the load distribution across the pivot points of the boom assembly.

In heavy machinery, bushings are used as sacrificial interfaces in pivot points and hydraulic cylinders. They function to reduce friction and wear between rotating or sliding components, protecting the primary structural members of the machine from direct metal-to-metal contact. Regular inspection of these components is necessary to monitor for clearance changes that may affect the precision of the hydraulic system.
