The Wacker Neuson Inner Raceway is a genuine OEM component designed for DPU and BPU series reversible vibratory plate compactors. As a direct factory replacement, this inner raceway meets the original engineering specifications for the exciter bearing assembly found across the DPU 4045H, DPU 5045H, and DPU 6055 model families, as well as the BPU 3545A and BPU 5045A. Sourcing the correct genuine OEM part for a high-load bearing surface like this one is critical — an improperly fitted or substandard raceway accelerates wear on adjacent components and can compromise the entire exciter unit. Keep part number on hand for planned maintenance or unscheduled repairs across your compactor fleet.
Key Features
- Genuine OEM Bearing Surface Accuracy — Manufactured to the original dimensional tolerances for the exciter assembly, ensuring the raceway seats correctly and distributes load evenly under high-frequency vibration cycles.
- Drop-In Exciter Assembly Fit — Engineered to install directly into the exciter housing of compatible DPU and BPU models with no reworking of mating components.
- Broad DPU and BPU Series Coverage — Confirmed fitment across the DPU 4045H, DPU 5045H, DPU 6055, BPU 3545A, and BPU 5045A reversible vibratory plate compactor families.
- Sustains Full Compaction Output — A worn or failed inner raceway causes vibration loss and uneven exciter rotation; replacing it with a correctly spec'd OEM part restores the machine's rated compaction force and travel performance.
- Long-Term Exciter Protection — Using the correct OEM raceway prevents accelerated wear on the outer race and rolling elements, extending the service life of the complete bearing set.
The inner raceway is the hardened inner ring of a rolling-element bearing, forming the precision contact surface against which the bearing's rolling elements — balls or rollers — travel. In a reversible vibratory plate compactor, the exciter shaft bearing assembly is subjected to continuous high-frequency loading as it generates the compaction force transmitted to the base plate. When the inner raceway becomes worn, pitted, or cracked, the bearing loses its smooth rolling action, causing increased heat, vibration irregularity, and eventually exciter shaft damage. Replacing a degraded inner raceway promptly protects the surrounding bearing components and keeps the compactor delivering consistent, full-rated compaction performance.
