195-30-66510 bogie Komatsu D375 bulldozer spare parts

The Komatsu D375 bogie 195-30-66510 is the “load-bearing steering core” of the chassis’s walking and steering system. By precisely connecting the frame and tracks, it transmits the machine’s weight and operating power, and works with the steering mechanism to achieve flexible steering. It also buffers the ground impact and vibration under harsh working conditions such as mining and infrastructure construction. Specifically designed for the steering parts of Komatsu D375A-2/A-5/A-6/A-8 models, it can prevent steering jamming, track deviation, and unstable walking caused by bogie deformation, cracking, and wear, ensuring normal equipment operation, improving construction efficiency, and meeting the stringent usage requirements of mining and large-scale earthmoving projects. It fits the product positioning of Komatsu D375 series bulldozers (474kW power, 72-ton working weight) for high-efficiency operation.
This product strictly adheres to Komatsu’s original standards and is based on the D375 series (474kW power, 72-ton working weight) chassis steering system specifications. It is constructed from Q355B high-strength steel plates, welded together, and equipped with wear-resistant bushings and fluororubber sealing components. It boasts advantages such as high load-bearing capacity, impact resistance, wear resistance, flexible steering, and convenient installation. Through precision cutting, robotic welding, and aging treatment, the welds are full and defect-free, resulting in high structural strength. The surface is treated with rust and corrosion prevention, allowing for direct installation. This effectively reduces downtime losses, extends the lifespan of the chassis steering system, and lowers maintenance costs. It is widely used in mining, earthmoving, and infrastructure fields, serving as a core component for steering system maintenance and perfectly aligning with the efficient and durable product positioning of the Komatsu D375 series bulldozers.
