1. What is a idler?
The joint between the idler wheel and the axle, featuring a keyed interface, provides a larger surface for bearing contact and improves the transmission of rotational force. This design increases the dependability and synchronizes the service life of the idler wheel with other components in the lower works. The idler wheel's rotation around fixed bearings results in lower stress at the contact points and less abrasion. A prolonged operational life of the track system results in fewer maintenance intervals, thereby reducing workers' risk of encountering safety risks.
2. Idler Characteristic
A genuine Front Idler
-
Significantly diminishes the stress on bearings by 50%, which alleviates the burden on components and prolongs their lifespan.
-
Robust protective shields safeguard against wear and tear caused by rocks and other particulate matter.
-
Contributes to the reduction of operational expenses in mining by prolonging the lifespan of the track system, thereby reducing the occurrence of unexpected work stoppages.
-
Enhances the efficiency of the track system by broadening the bearing surface and optimizing the distribution of lubricant.
Increased Productivity
-
Splined connection between idler and shaft increases reliability and matches idler life with that of other lower works components
-
Bearing blocks with bushings can be removed without breaking the track
-
Dedied lube injectors supply lubricant to critical wear surfaces
Lower Total Cost Of Ownership
-
50% less bearing stress reduces bearing loads and increases component life
-
Rotating shaft within stationary bushings produces less contact stress and wear
-
Heavy-duty rock guard prevents dirt and debris from damaging parts
