    Sprockets are metal cogwheels that consist of a metal inner ring with bolt holes or a compression hub and a gear ring in one unit. Sprockets can be screwed on directly, or pressed onto the machine’s drive hub, and they are usually used for excavators.
    Just as sprockets, segments also consist of a metal inner ring with bolt holes and a gear ring. Unlike sprockets, segment groups exist from individual segments which make up the sprocket for the undercarriage of bulldozers. This means that the segments can be exchanged without dismantling the track link.
    *Our sprockets are meticulously designed and manufactured to ensure optimal performance and durability, making them the ideal choice for excavators and other heavy-duty equipment.
    Crafted from premium-grade materials, our sprocket rims feature a metal inner ring with bolt holes or a compression hub, along with a gear ring, all in one unit. This robust construction guarantees exceptional strength and resistance to wear and tear, even in the most demanding working conditions. Whether you need to replace worn-out sprockets or upgrade your machinery for enhanced efficiency, our Caterpillar Bulldozer Sprocket Rim D4D(29T) is the reliable solution you can trust.
    Installation is a breeze, as our sprockets can be easily screwed on or pressed onto the machine’s drive hub, ensuring a secure and stable fit.
