Wacker Neuson 5000118930 Wave Spring

The Wacker Neuson Wave Spring is a genuine OEM component designed for the RD11AEC, RD11V, and RD11A hydrostatic double drum vibratory rollers. As a direct factory replacement, this spring ensures correct load distribution and mechanical compliance within the assembly it serves. Genuine OEM sourcing means the is built to the exact tolerances specified for these RD11-series machines, so you can install it with confidence and get your roller back to work fast.

Key Features

• Correct Spring Rate for Drum Assembly Loads — Engineered to the precise deflection and load characteristics required for the RD11-series roller, ensuring the assembly performs as designed under compaction stress.
• Genuine OEM Part — Sourced directly from Wacker Neuson, so material grade, temper, and geometry match the original specification without substitution or compromise.
• Drop-In Replacement for RD11-Series Rollers — Fits the RD11AEC, RD11V, and RD11A hydrostatic double drum vibratory rollers; seats into the existing mounting position with no adaptation required.
• Maintains Consistent Clamping and Damping Force — A fatigued or broken wave spring causes uneven force distribution in the assembly, leading to vibration irregularities or premature wear on mating components; replacing it restores proper function.
• Verified Part Number — Order by part number 5000118930 to confirm you are receiving the correct spring for your specific RD11 configuration.

A wave spring is a precision-formed, coiled spring with a wavy, sinusoidal profile that allows it to deliver controlled axial load and deflection within a compact space. In roller and drivetrain assemblies, wave springs are commonly used to preload bearings, maintain consistent clamping force between rotating components, or take up axial play in a shaft stack. When a wave spring fatigues, flattens, or fractures, the components it preloads can develop excessive play, leading to accelerated bearing wear, vibration anomalies, or loss of proper engagement in the assembly it supports.
