Vogele Asphalt paver conveyor roller
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 gravity. Therefore,requires reliable sealing, small wear resistance and rolling resistance.
