Core Component Kit

• Cylinder Block (Rotor): High-rigidity alloy steel with precision machining of inner bores and valve plate mating surfaces, ensuring smooth piston reciprocation, wear resistance, and impact resistance.
• Pistons & Shoes: Set of 9 high-precision piston assemblies with special surface hardening. Stable displacement via swashplate interaction, low friction, long service life.
• Valve Plate: Bimetallic composite structure optimizes oil flow, improves volumetric efficiency, and reduces operating noise.
• Retainer Plate & Springs: Robust return mechanism ensures consistent piston-shoe contact with swashplate for stable suction/delivery.
• Bearings & Seals: Tapered roller bearings for high load capacity; Viton lip seals for oil resistance, high temperature resistance, and leak prevention.
• Control Spools/Valve Plates: Compatible with Load Sensing (LS) and Pressure Compensator (PC) controls for precise swashplate angle and flow regulation.
