Rollers: The rollers are fixed under the wheel frame with screws to support the mass of the machinery and distribute the mass over the track shoes. At the same time, it also relies on its roller flange to clamp the chain rail so that the track does not slip laterally (derailment), ensuring that the machine moves in the direction of the track, with small rolling resistance and the life of the operation in mud and water.
Drag sprockets: prevent the sagging of the track and the falling off of the track when walking and reduce its up and down vibration
Idler: The idler is mounted on the track and is used to guide the track
Our products are according to the standard of OEM to manufacture.

1PCDrag sprocket function: the carrier roller is used to reduce the track sag between the idler and the drive sprocket, and support the track loose edge from the drive sprocket, and when the track in the engagement is tightened, it is used to guide the track to disengage from the mesh, when installing a drag sprocket, it should not be placed in the middle of the wheel base, but closer to the drive sprocket. It is worth noting that if the diameter of the e-mail sprocket is too small, there is a possibility that the track will slip along the e-tramp rim, which will grind out a "light plane" according to the wear of the e-mail rim, which will cause the e-chainer to stop rotating.
Drag sprocket installation arrangement: when the drag sprocket is installed on the excavator, a single arm support is adopted, and the support block is heightened, so that the space below is increased, and the obstruction of silt and stones is avoided when walking, and the wear between the track section and the reducer bearing is also avoided, and the passability of walking is improved.
