1. What is a idler?
The keyway coupling between the idler and the axle offers an expanded surface for bearing and more efficient transmission of torque, which enhances dependability and synchronizes the service life of the idler with other components in the lower assembly. The rotation of the axle within the fixed bearings results in diminished frictional stress and erosion. An extended lifespan of the track system leads to fewer replacement cycles, thereby minimizing workers' exposure to hazardous conditions.
2. Idler Characteristic
A genuine Front Idler
-
Cuts down on stress on bearings by 50% to lighten the load on bearings and prolong the lifespan of parts.
-
Sturdy rock shields defend against harm from soil and rubble.
-
Contributes to the reduction of mining operational expenses by prolonging the life of the track system and reducing unexpected stoppages.
-
Enhances track performance by broadening the bearing surface and improving the distribution of lubrication.
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
Enhanced Safety
-
Longer crawler system life increases change-out intervals reducing employee exposure to safety risks from system change-outs and component replacement
