The Wacker Neuson is a genuine OEM Shaft Seal 20 X 52 X 7 2B designed for the A5000, L5000, M2500, and H65 internal concrete vibrator series. Sourced directly from Wacker Neuson, this seal meets the exact dimensional and material specifications of the original component installed at the factory. It is confirmed to fit the A5000/160 ISO, A5000/160 ANSI, A5000/160B, L5000/225 ISO, L5000/225 ANSI, M2500/120, M2500/230, and H65 vibrator head models. When your existing seal shows signs of oil weeping or vibrator head wear, part is the correct direct replacement to restore proper function.
Key Features
- OEM-Spec Sealing Material — Manufactured to the original lip geometry and compound grade required to contain lubrication oil under the high-frequency oscillation loads produced by internal concrete vibrators.
- Exact Dimensional Fit — Cut to a 20 x 52 x 7 mm cross-section, this seal seats correctly into the original housing bore without rework or shimming.
- Broad Vibrator Series Coverage — Fits A5000/160 ISO and ANSI, A5000/160B, L5000/225 ISO and ANSI, M2500/120, M2500/230, and H65 vibrator head models across both US and EU configurations.
- Protects Internal Drive Components — A correctly seated shaft seal keeps bearing lubricant in and concrete slurry out, preserving the service life of the drive shaft and needle bearings inside the vibrator head.
- Genuine Wacker Neuson OEM Part — Supplied as original equipment, so the part number, material grade, and geometry match the unit's original specification without substitution.
The shaft seal in an internal concrete vibrator sits at the point where the eccentric drive shaft exits the vibrator head housing. Its job is to retain the lubricating oil that protects the internal bearings and eccentric weight while simultaneously blocking cement paste, water, and aggregate fines from migrating inside the head. When this seal deteriorates — through compression set, lip wear, or chemical breakdown from concrete contact — oil leaks outward and abrasive slurry works inward, accelerating bearing wear and ultimately causing vibrator head failure. Replacing a worn shaft seal promptly with the correct 5000029790 unit restores the fluid barrier and keeps the drive assembly running at full consolidation power.
