Pin bushing for Palfinger PK 38502

The pin bushing, identified by part number ELG168, functions as a bearing surface within the articulation points of heavy machinery, specifically within the boom and stabilizer assemblies of hydraulic cranes. By providing a controlled interface for the movement of a pin within its housing, this component protects structural elements from direct contact and wear. It is engineered to manage radial loads and friction during the operation of the crane's articulated sections, ensuring that the joints maintain proper alignment and movement without excessive clearance.

This component is compatible with the Palfinger PK 38502 crane model. It is designed to fit into the pivot points of the boom, arms, and stabilizer systems where consistent movement under load is required. Proper installation of this bushing is necessary to maintain the operational precision of the crane during lifting tasks.

In heavy equipment, bushings are used in various pivot points to allow for rotational movement between connected components. These parts act as the sacrificial wear surface, absorbing the mechanical stress of the joint. By replacing these bushings at appropriate maintenance intervals, operators can prevent damage to the more expensive pins and structural housings, thereby preserving the stability and control of the crane's articulated systems.
