The Wacker Neuson Bearing Housing is a genuine OEM component designed for the RD27-100 and RD27-120 series hydrostatic vibratory and tandem rollers. Sourced directly from Wacker Neuson, this part meets the exact tolerances and material specifications set for the original equipment — no guesswork on fit or function. It is a direct replacement covering a wide range of RD27 configurations, including Pro and Basic T4F variants across both the RD27-100 and RD27-120 model families. When you order by part number, you can be confident you're getting the correct housing for your machine.
Key Features
- Precision-Toleranced OEM Construction — Manufactured to the exact bore dimensions and material grade specified by Wacker Neuson, ensuring the bearing seats correctly and maintains proper shaft alignment under vibratory load.
- Drop-In Replacement — Matches the original mounting pattern and housing geometry for the RD27 series, allowing straightforward installation without reworking surrounding components.
- Broad RD27 Series Coverage — Fits RD27-100 and RD27-120 models across Hydrostatic Vibratory Roller, Ride-On Roller, RD27 Pro Tandem Roller, and Basic T4F configurations.
- Protects Drivetrain Integrity — A correctly fitted bearing housing keeps the drum drive bearing properly supported; a worn or cracked housing allows bearing movement that accelerates wear and can lead to costly drivetrain damage.
- Genuine Wacker Neuson Part — Carries the full backing of Wacker Neuson's OEM parts program, so you're installing a component built to the same standard as the original part that left the factory.
The bearing housing is a structural support component that locates and retains the drum drive bearing in its correct position within the roller's drivetrain. It holds the bearing firmly against radial and axial forces generated during compaction, keeping the drum shaft running true under heavy vibratory loads. When the housing cracks, wears out of round, or loses its press-fit integrity, the bearing can shift position, causing uneven wear, vibration anomalies, and eventual failure of the bearing and surrounding shaft components.
