195-30-62400 pin assy Komatsu D375 bulldozer spare parts

The Komatsu D375 pin assembly 195-30-62400 is the “positioning and transmission core” of the chassis articulation system. Through precise positioning and articulation, it transmits the operating power of the machine body and buffers the impact load under harsh working conditions such as mining and infrastructure. It is specially designed for the chassis articulation parts of Komatsu D375A-2/A-5/A-6/A-8 models, which can avoid articulation jamming and power transmission problems caused by pin assembly wear and breakage, ensure normal equipment operation, improve construction efficiency, and meet the harsh use requirements of mining and large-scale earthwork projects.
This product strictly adheres to Komatsu’s original standards and is manufactured using the chassis articulation system specifications of the D375 series (474kW power, 72-ton operating weight). Forged from high-quality 45# steel, and equipped with wear-resistant bushings and sealing components, it boasts advantages such as wear resistance, impact resistance, precise positioning, and easy installation. Through precision forging and carburizing hardening, it features high structural strength and precise dimensions, allowing for direct installation. This effectively reduces downtime losses, extends the lifespan of the chassis articulation system, and lowers maintenance costs. Widely used in mining, earthmoving, and infrastructure fields, it is a core component for articulation system maintenance, perfectly aligning with the efficient and durable product positioning of the Komatsu D375 series bulldozers.
