Design:
9–11 hardened steel pistons with a chrome-plated cylinder block for wear resistance .
Variable-displacement mechanism: Hydraulic servo pistons adjust the swashplate angle to control flow, reducing energy waste.
Materials:
Heat-treated alloy steel drive shaft for torsional rigidity.
Cast iron housing with internal oil passages for lubrication and cooling (operating temperature: -15°C to 90°C / 5°F to 194°F) .
