Our dozer undercarriage parts cover a full range of mainstream models, including those for Caterpillar D6/D7 series, Komatsu D65/D85 series, John Deere 650K/750K series, Volvo SD160/SD200 series and more than 30 popular models, from track chains, supporting wheels to guide wheels, drive wheels, we can provide precisely matched original factory-grade replacement parts.These parts are widely used in mining, construction, farmland renovation, road construction and other operations: in mining environment, the track chain made of high hardness and wear-resistant steel can resist the continuous impact of sharp rocks and reduce the risk of link breakage; in muddy and wetland construction, the sealed supporting wheel can prevent mud and water from penetrating into the bearing and avoid jamming; in high temperature or cold area, the special heat-treated drive wheel can maintain stable transmission performance and ensure the stability of the drive wheel.
In hot or cold areas, the special heat-treated drive wheels can maintain stable transmission performance and ensure the normal operation of the equipment in extreme temperatures ranging from -30℃ to 50℃.For different working intensity, we also subdivided into two series: “Standard” and “Heavy Duty” - the standard model is suitable for regular earthmoving projects with outstanding cost-effectiveness; the heavy duty model adopts thickened steel and reinforced chain pins, designed for heavy mining projects with average daily operation of more than 12 hours, and the service life is increased by 40% compared with the standard model to meet the durability demand of various working conditions in an all-round way. The heavy-duty model is designed for heavy mining projects with more than 12 hours of daily operation, and its service life is increased by 40% compared with the standard model.

The Komatsu D85 in our mine used ordinary track chain before, and had to be replaced once in two months, since the replacement of this heavy-duty type parts, track chain and drive wheels lasted half a year is still very solid. Especially the wear-resistant coating at the chain pin, rubbing so long in the gravel, actually not much paint, more durable than expected too much time, downtime maintenance time is reduced by a large part.
Southern rainy season in the rice paddies bulldozing, the previous support wheel always rust stuck. Changed their models with double seal, three months down the wheel body clean, bearing rotation smooth, no noise. Customer service also specially recommended according to the model rust-proof models, especially thoughtful, next time certainly buy again.
Municipal engineering Liugong 200 replaced a full set of chassis parts, a year in the gravel roads, dirt piles back and forth, the track chain did not loosen, supporting wheel did not leak oil. Calculated than the original parts to save nearly half the money, life is almost the same, the small engineering team to choose this is too valuable.
I've bought other parts before, either the hole position is not right or the size is a little worse, just debugging will take a day. This time the Volvo SD160 drive wheel and guide wheel, unboxing directly mounted, tight, boot try a little bit not lagging, the master said that this precision is no difference with the original.
