Part Name: Motor Grader Blade Lift Hydraulic Cylinder Group / Assembly
Technical Specifications: Bore: 76.20 mm / Stroke: 1,170.00 mm / Weight: ~61 kg / Hydraulic Cylinder
Compatible Machinery: Caterpillar Motor Graders (120H, 120H ES, 120H NA, 120K, 120K 2, 135H, 135H NA series)
What It Does:
Serves as the primary blade lift hydraulic cylinder actuator mounted between the main front frame and the circle/moldboard assembly on Caterpillar 120H, 120K, and 135H series motor graders. Powered by high-pressure hydraulic fluid, it extends and retracts through a 1,170.00 mm stroke to independently raise, lower, and position the left or right side of the grader moldboard, maintaining precise blade elevation and cutting slope angles.
Importance:
A critical precision-control hydraulic drive component essential for accurate grading, surface leveling, road profiling, and fine finishing operations. Engineered with a robust 61 kg heavy-walled barrel and induction-hardened, chrome-plated rod construction, it effectively withstands severe axial impact shocks, continuous grading vibrations, and bending stresses transmitted from the cutting edge, while high-performance seals eliminate internal bypass and cylinder drift to keep the blade securely locked at the target grade.
