Roll pin for Terex BT4792

The roll pin, part number 224-19017, is a hollow cylindrical fastener used to secure components within the Terex BT4792 crane. This component features a longitudinal slot that allows it to compress when inserted into a hole, generating radial tension that holds it securely in place. It measures 1/2 inch in outside diameter and 1 1/4 inches in length.

This pin is used in various mechanical assemblies on the Terex BT4792 to maintain the relative position of parts, such as securing gears to shafts or acting as a pivot point for levers and other linkages. The design allows for a secure connection that can be removed during maintenance procedures without the need for additional locking hardware like nuts or washers.

Roll pins serve as critical fasteners in heavy machinery, providing a reliable method to align components or act as shear pins in mechanical systems. By exerting constant pressure against the walls of the mating hole, they remain stable even in applications subject to operational vibration.
