The steering cylinder is a vital actuator within the Caterpillar 120G's hydraulic system. Its primary function is to articulate the machine by pivoting the front frame relative to the rear frame. This articulation is the primary method of steering for most motor graders. The 120G utilizes a single, double-acting hydraulic cylinder to perform this task. The operator's input at the steering wheel is converted into hydraulic pressure, which acts upon this cylinder to extend or retract the rod, thereby turning the machine left or right.
This 3G-8070 steering cylinder is used for 120G 12G 130G 140G 160G motor grader.
