195-30-66531 pad Komatsu D375 bulldozer spare parts

The Komatsu D375 pad 195-30-66531 is the “sealing and buffering core” of the chassis connection system. By tightly fitting the joint surfaces of components, it achieves sealing and leak prevention, cushioning and vibration reduction, and isolation from the intrusion of impurities such as mud, water, and dust. It is specially designed for the chassis joint parts of Komatsu D375A-2/A-5/A-6/A-8 models. It can prevent oil leakage, component wear, and loosening caused by pad aging, damage, and deformation, ensuring normal equipment operation, improving construction efficiency, and meeting the stringent use 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 chassis connection system specifications of the D375 series (474kW power, 72-ton working weight). It is molded from high-quality nitrile rubber (NBR) with a reinforced fiber layer, offering advantages such as excellent sealing performance, wear resistance, aging resistance, impact resistance, and easy installation. Through precision molding and vulcanization, it boasts accurate dimensions, a high degree of fit, and excellent toughness, allowing for direct installation. This effectively reduces downtime losses, extends the lifespan of chassis connection components, and lowers maintenance costs. Widely used in mining, earthmoving, and infrastructure fields, it is a core component for chassis connection system maintenance, perfectly aligning with the efficient and durable product positioning of the Komatsu D375 series bulldozers.
