The Cylinder Block Assembly is a core rotating component for A4VG125 axial piston pumps. It houses the pistons and enables precise reciprocating motion to convert mechanical drive energy into hydraulic flow. Manufactured from high-grade alloy steel and finished with precision honing, it ensures exceptional durability, smooth piston travel, and optimal hydraulic efficiency under high-pressure operation.
Features:
Compatible with Rexroth A4VG125 axial piston pumps.
Precision-machined bores for accurate piston alignment and sealing.
Surface-hardened for maximum wear and fatigue resistance.
Internal spline designed for precise engagement with the drive shaft.
Maintains excellent volumetric efficiency and low leakage.
Applications:
Used in hydrostatic transmissions, mobile hydraulic drives, and heavy-duty industrial systems employing A4VG125 series pumps.
Function:
The Cylinder Block holds the pistons that move axially within their bores as the swash plate tilts. This reciprocating motion creates alternating suction and pressure phases, generating continuous hydraulic flow. Its precision machining ensures consistent performance, smooth rotation, and long service life even in demanding hydraulic environments.
