1. What is a idler?
The keyed joint between the idler and the axle offers an expanded bearing surface and enhanced torque transmission, which boosts dependability and synchronizes the service life of the idler with other components in the undercarriage. The axle rotating within the fixed bearings results in diminished friction and stress. An extended service life of the track system leads to fewer replacement cycles, thereby minimizing the risk of accidents to workers.
Cuts the load on bearings by half, thereby reducing the stress on bearings and prolonging the lifespan of parts.
Sturdy rock shields safeguard against dirt and debris-induced damage.
Contributes to the reduction of operational expenses in mining by prolonging the lifespan of the crawler system and reducing unexpected stoppages.
Enhances the efficiency of the track system by expanding the bearing surface and improving the distribution of lubrication.
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
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
