Excavator Undercarriage Spare Parts Bulldozer Top Roller Carrier and Upper Roller for Komatsu D50 Construction Machinery Crane

Product Description

In the operations of excavators and bulldozers, chassis components play a crucial role. As a leading supplier of excavator chassis components, we bring you outstanding products with decades of professional experience, a vertically integrated quality control system and innovative internal R&D. Our product line covers various core components such as Carrier (support Wheels), Sprocket (Sprockets), Drive Sprockets (drive sprockets) and Idler Wheels (idler wheels). Whether it is excavator chassis parts or bulldozer chassis parts, it can meet your needs.

Among them, Carrier Wheels are forged from super high-quality steel, featuring excellent wear resistance, strong load-bearing capacity and outstanding anti-friction performance. Even in rough terrain, they can provide stable support for excavators and bulldozers. Sprocket Wheels are made of high-quality materials. The precisely processed tooth profile enables them to have a self-cleaning function. They can not only efficiently transmit power but also reduce chain wear.

The unique structure can withstand high torque. The Drive Sprockets adopt advanced forging technology, anti-slip contour design, precise meshing to ensure reliable power transmission, and the surface treatment process further enhances durability. Idler Wheels are precisely manufactured from sturdy materials and have built-in shock absorption devices. They can effectively maintain the tension of the tracks, withstand impact forces and have anti-debris functions.
