Locking pins are key positioning fasteners in construction machinery, mainly used for positioning and locking hinged components such as pins, bushings, and connecting rods, constraining axial and radial clearances of components, and maintaining the fitting accuracy of each linkage component. Made of high-strength alloy steel, and subjected to quenching hardening and tempering strengthening treatment, they are resistant to shearing, extrusion, and deformation, making them suitable for long-term high-frequency vibration and continuous heavy-load operation scenarios on construction sites.
This product is of original factory standard specifications, with precise dimensions and tight tolerances, ensuring a high degree of fit and secure positioning. It boasts excellent wear resistance, aging resistance, and fatigue resistance, making it resistant to wear, bending, and breakage even under prolonged stress. Old and worn-out locking pins are prone to wear, bending, deformation, breakage, and missing parts, leading to excessive component gaps, structural noise, linkage jamming, and component misalignment wear, affecting equipment operating accuracy. This product supports in-situ non-destructive replacement, is suitable for equipment maintenance, overhauls, and bulk stocking, effectively reducing equipment maintenance and failure costs.
