Custom Heavy-Duty Hydraulic Cylinder for Mining Equipment Replacement
The APEX-CMDC heavy-duty hydraulic cylinder is specifically designed for mining and quarry equipment, including excavators, wheel loaders, and haul trucks. Built to withstand high shock loads, abrasive dust, and extreme temperatures, it ensures reliable operation in the most demanding environments. With a bore range of 50–320 mm and working pressure up to 250 bar, it delivers the force needed for boom lifting, bucket operation, and material handling. The heavy-duty roundline structure with replaceable gland provides durability and easy maintenance.
