Wacker Neuson 5002003821 Shaft Seal 35 X 52 X 7 2B

The Wacker Neuson Shaft Seal 35 X 52 X 7 2B is a genuine OEM component designed for the DPS1850H Vario, DPS2040, and DPS2050 single direction vibratory plate series. As a direct Wacker Neuson OEM part, is manufactured to the exact material grade and dimensional tolerances required for a leak-free, long-service installation. This seal fits the specified shaft bore precisely, eliminating the guesswork that comes with sourcing an incorrect replacement. Confirm your model against the fitment list below before ordering to ensure a correct match.

Key Features

• OEM-Grade Seal Material — Manufactured from the compound and durometer specified by Wacker Neuson, delivering the compression characteristics needed to maintain a reliable sealing interface on the vibratory plate driveshaft.
• Correct Dimensional Spec: 35 x 52 x 7 — The 35 mm inner diameter, 52 mm outer diameter, and 7 mm width match the original bore and housing exactly, allowing direct installation without machining or shimming.
• Fits Key DPS Vibratory Plate Models — Compatible with the DPS1850H Vario, DPS2040 (20kN, 40 cm), and DPS2050 (20kN, 50 cm) single direction vibratory plates.
• Prevents Oil and Lubricant Loss — A correctly seated shaft seal keeps exciter housing oil where it belongs; a worn or hardened seal allows leakage that accelerates internal bearing and gear wear.
• Genuine Wacker Neuson OEM Part — Sourced directly through the Wacker Neuson parts network, so you receive the same component installed at the factory — no substitutions or dimensional compromises.

A shaft seal forms a dynamic barrier between a rotating driveshaft and the surrounding housing, preventing lubricating oil from escaping while keeping contaminants such as dirt and water out of the exciter assembly. On a vibratory plate compactor, the exciter unit generates the high-frequency compaction force, and its internal components depend on a consistent oil bath to stay lubricated under continuous vibration loads. When the shaft seal wears, hardens, or becomes damaged, oil migrates out of the housing, leading to dry-running conditions that quickly degrade bearings and eccentric weights — eventually causing costly exciter assembly failure and unplanned downtime on the job.
