Description
VD48/42 Plunger Pair
The VD48/42 represents a critical precision component set for axial piston hydraulic units. This pair consists of a hardened steel plunger (piston) that reciprocates within a precisely honed bore in the barrel (cylinder block).
The VD48/42 represents a critical precision component set for axial piston hydraulic units. This pair consists of a hardened steel plunger (piston) that reciprocates within a precisely honed bore in the barrel (cylinder block).
Component Designation: The nomenclature"VD48/42"indicates a plunger with a nominal diameter of 48 mm and a stroke length of 42 mm.
Function: It operates within a swashplate or bent-axis design, converting mechanical rotational energy into hydraulic energy (in a pump) or vice versa (in a motor). The reciprocating motion of the plunger draws in and expels hydraulic fluid, creating flow and pressure.
Key Features:
1. Precision Machining: Both components are manufactured to extremely tight tolerances and super-finished to achieve an optimal running clearance.
2. Material & Hardness: Fabricated from high-grade alloy steel, followed by heat treatment and surface hardening to ensure exceptional wear resistance and long service life.
3. Performance: The precise fit is crucial for maintaining high volumetric efficiency, preventing excessive internal leakage, and sustaining the high pressure ratings of the pump or motor.
4. Application: This part is essential for the repair and overhaul of high-performance hydraulic pumps and motors used in industries such as construction, marine, industrial machinery, and press manufacturing.
