Caterpillar Bulldozer Track Roller D11N

Tack offers a complete range of track rollers for both excavators and bulldozers.  Bottom rollers for bulldozers have a large running surface due to mobile working. Tack rollers are produced with high-quality steel and special heat treatments to make excavator and dozer rollers extra tough and thus wear-resistant . The bottom rollers have a larger oil reservoir, so that the roller can be cooled sufficiently, our production is finished with precision tools, high-grade seals and bronze bushings to greatly improve oil leakage problem. Based on all the strict requirements in production  we can guarantee a long service life , even with intensive use or in extreme working conditions.
