1. What is idler?
The splined connection between idler and shaft provides more bearing area and better torque transfer, increasing reliability and matching idler life with that of other lower works components. Rotating shaft within stationary bushings produces less contact stress and wear. Longer crawler system life increases change-out intervals reducing employee exposure to safety risks.

- Reduces bearing stress 50% to decrease bearing loads and increase component life
- Heavy-duty rock guards protect against damage from dirt and debris
- Helps to lower mine operating costs by extending crawler system life, minimizing unplanned downtime
- Provides greater track efficiency by increasing bearing area and lube distribution
- 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
