Description

Bulldozer undercarriage is composed of sprocket, track link assy, idler, track roller, carrier roller and so on. The Idlers guide the track in and out of the track rollers. They also intermittently support the machine's weight and provide a way to control track slack and tension.

Reduces bearing stress 50% to decrease bearing loads and increase parts' life.

Heavy duty rock guards protect against damage from dirt and debris.

Helps to lower mine operating costs by extending crawler system life.

Provides greater track efficiency by increasing bearing area and lube distribution.

Dedicated lube injectors supply lubricant to critical wear surfaces.

Rotating shaft within stationary bushings produces less contact stress and wear.

Heavy-duty rock guard prevents dirt and debris from damaging parts.
