The Wacker Neuson Hydraulic Cylinder is a genuine OEM component designed for the RD27-100 and RD27-120 hydrostatic vibratory tandem rollers, including standard and traction control configurations. As a factory-sourced part, is manufactured to the exact tolerances and material specifications of the original component it replaces, ensuring a direct, accurate installation. This cylinder is verified across multiple serial number ranges of the RD27 series, covering both the RD27-100 and RD27-120 machine families. When hydraulic cylinder integrity is critical to roller steering and articulation response, trusting a genuine OEM part like this one protects both machine performance and operator safety.
Key Features
- Genuine OEM Sealing and Bore Tolerances — Manufactured to the original hydraulic pressure ratings and cylinder bore dimensions, preventing internal leakage and pressure loss that an off-spec cylinder can cause.
- Direct-Mount Replacement — Engineered to match the original mounting points, port fittings, and rod dimensions of the RD27 series for a straightforward swap with no reworking of hydraulic lines.
- Broad RD27 Series Coverage — Confirmed fitment across RD27-100 and RD27-120 tandem rollers in both standard and traction control configurations, spanning multiple production serial number ranges.
- Sustained Hydraulic Output — A properly functioning hydraulic cylinder maintains consistent articulation force and steering response, which is essential for accurate pass control and straight tracking on asphalt and soil.
- Hydraulic System Integrity — Cylinder failure in a hydrostatic roller can cause uncontrolled articulation or total loss of steering authority. Replacing with a genuine OEM unit restores safe, predictable machine handling.
The hydraulic cylinder on the RD27 tandem roller is a key actuator in the machine's articulated steering system. It converts hydraulic pressure from the machine's hydrostatic circuit into linear force, allowing the operator to steer and maneuver the roller across compaction passes. When the cylinder develops internal seal wear, scoring, or fluid bypass, steering becomes sluggish or inconsistent — and in severe cases the machine can lose directional control entirely. Replacing a worn or failed cylinder with a genuine OEM part restores the precise hydraulic force balance the RD27's steering geometry depends on.
