Wacker Neuson 5000039999 Grooved Ball Bearing

The Wacker Neuson 5000039999 is a genuine OEM Grooved Ball Bearing designed for the DPU4045H, DPU4545H, DPU5045H, DPU5545H, DPU6055, DPU6555H, and DPU7060 series reversible vibratory plate compactors. As a factory-sourced component, the part is manufactured to the exact tolerances required for proper fit and function within the exciter housing of these heavy-duty diesel plate compactors. This bearing serves one of the broadest fitment ranges in the DPU lineup, covering decades of production variants including He, Heh, Hec, Heap, and US-market configurations. Confirm your model number before ordering to ensure compatibility with your specific unit.

Key Features

• OEM-Grade Radial Load Tolerance — Sourced directly from Wacker Neuson, this grooved ball bearing meets the exact radial and axial load ratings specified for DPU-series exciter assemblies, where substandard bearings fail prematurely under continuous vibration stress.
• Drop-In Fitment for DPU Exciter Assemblies — Engineered to seat correctly in the exciter housing without shimming or machining, maintaining proper shaft alignment and bearing preload across all covered variants.
• Broad DPU Series Coverage — Fits a wide range of Wacker Neuson reversible vibratory plate compactors including DPU4045H, DPU4545H, DPU5045H, DPU5545H, DPU6055, DPU6555H, and DPU7060 models, including He, Heh, Hec, Heap, and US-spec variants.
• Sustained Compaction Output — A correctly functioning bearing allows the exciter shaft to spin true at operating RPM, delivering consistent centrifugal force to the plate. A worn bearing causes vibration imbalance, reduced compaction force, and accelerated wear to surrounding components.
• Genuine Wacker Neuson Part — Supplied as authentic OEM stock under part number 5000039999, ensuring the correct geometry, material grade, and sealing specification for the high-cycle vibration environment inside a diesel reversible plate compactor.

A grooved ball bearing — also known as a deep-groove ball bearing — supports the rotating exciter shaft inside the compactor's vibration mechanism, absorbing both radial loads generated by the eccentric weights and any incidental axial forces during operation. In a reversible vibratory plate compactor like the DPU series, the exciter assembly runs at high speed continuously throughout the compaction cycle, placing significant and sustained demand on these bearings. When a grooved ball bearing wears out or loses its grease charge, the exciter shaft develops play, vibration output becomes uneven, noise increases, and — if left unaddressed — the bearing can seize and cause secondary damage to the exciter housing or shaft journals.
