Description: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.
Advantages: Track roller walks as important as human's backbone.Track shaft especially track roller bears high load when it is milling.They need keep normal walk when absorbing high load from machine.Our high quality track rolelr fix in rolling bearing, which special design for every machine models to reduce friction.That is guarantee excellent operating performance and long working life.Our company is the sole supplier to supply track roller for Dynapac.The specific advantages as belows:
1, Sealing ring made of heat-resistant materials.
2, No deviation,permanent,and porous casting material provide good lubrication.
3, Connect grinding sealing ring.
4, Additional oil passage.
5,Full of synthetic biochemical degradation of lubricating oil.
6,High strength open lock forming the earth's axis end locking.
Working Principles: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.
.Driving crawler track connecting pin by improving boron manganese steel alloy forging and become, have high rigidity and long life.
2.Using high frequency hardening process make contact surface also has a very long service life.
3.Track geometry to reduce its best heat in particular the critical voltage within the scope of the load, so as to improve its fatigue strength.
4.The installation of automatic fastening nut of the makes crawler accurate and simple.We can supply the crawlwer track of some famous brands such as Wirtgen,Dynapac,Betteli,XCMG,SANY and so on.
