Pin for Komatsu machinery

The 113-78-21170 pin is a mechanical component designed for use in Komatsu heavy machinery. It functions as a critical connection point within the equipment, often utilized in the articulation of arms, buckets, or the secure fastening of structural assemblies. By acting as a pivot or anchor point, this part transmits forces and supports loads while allowing for the necessary relative movement between connected machine sections.

This component is manufactured by Komatsu and is compatible with a range of their heavy equipment, including excavators, bulldozers, and front-end loaders. It is engineered to maintain precise tolerances at pivot points, ensuring that structural components remain properly aligned and secure during operation. The dimensions and design of this pin are specific to the mechanical requirements of the assembly it serves within the machine.

In heavy machinery, pins of this type are used to join components that must pivot or remain fixed under stress. They are typically installed within bushings or housings to manage the mechanical forces exerted during daily operations. Regular inspection and lubrication of these pivot points are standard maintenance practices to ensure the pin continues to function correctly and to prevent excessive wear on the surrounding assembly.
