track roller 118719 for W2200 road milling machine

Track roller is one of an important parts in system spare parts during milling machine working.When milling machine milling deeper, it also can guarantee the speed fast.Track shaft especially track roller bears high load when it is milling.They need keep normal walk when absorbing high load from machine.

Track roller support the gravity of machine,so it drives in crawler track or track pad.Therefore,they are used to fix track pad in order to protact from going the wrong and regularly driving the track pad.Sometimes milling machine working in slurry condition and take charge of the most gravity. Therefore,requires reliable sealing, small  wear resistance and rolling resistance.
