Roller with pin for Link-Belt HC238H

The roller with pin, part number 3A19981, serves as a component of the undercarriage assembly for crawler cranes. Its function is to guide the track chain and distribute the weight of the machine across the ground surface, which assists in the movement and stability of the equipment. The integrated pin secures the roller to the undercarriage frame while allowing for rotation during operation.

This component is designed for the Link-Belt HC238H crawler crane. It is compatible with specific units within this crane line, including those with serial number H9J1-3785. The assembly is engineered to fit the undercarriage configuration of this model to maintain proper track alignment and load distribution.

Undercarriage rollers provide a rolling surface for the track chain to travel on, which reduces friction between the track and the machine frame. By supporting the weight of the crane, these rollers ensure that the track remains positioned correctly during travel. Proper maintenance of these components is required to prevent track misalignment and to support the structural integrity of the undercarriage system during operation.
