Durable Bottom Rollers & Top Rollers for Tough Construcion and Mining Tasks
Crafts track rollers and carrier rollers are according to the standard of OEM to manufacture. The main pin shaft of our roller is made by round steel, and the shell are forged by special steel. Both of the shaft and the shell are hardened by the heat treatment deep to 6mm and up to the HRC 56° around, to make sure they are hard enough to cover the bad work condition. Crafts track rollers and carrier rollers have great lubricated system. Meanwhile, we choose the high hardness ware-resisting alloy chrome & molybdenum floating seal and elastic rubber O-ring, and take the good quality bimetal bronze bushings to keep our roller quality always in a real high level. After assembling, each of Crafts track roller and carrier roller would be put under water to test its sealing property. Moreover, there is also a Rolling fluency testing to prove that they are ready to work. When all the processes are finished, the track roller and carrier roller will be painted and packing and wait for the loading and shipping.

The track roller is also called bottom roller, while the carrier roller is sometimes called top roller. The function of the track roller is to convey the weight of an excavator to the ground. When an excavator is run on uneven ground, track rollers carry a tremendous impact. Therefore, the track rollers always support huge load during the operating. Moreover, because of the extremely bad work condition, the track rollers really need a very good sealing to prevent dirt, sand, and water from damaging it. The following is parts of what brands and models that our track rollers and carrier roller can be perfect fit.
