The Wacker Neuson Pillow Block is a genuine OEM component designed for the RD27-100 and RD27-120 series hydrostatic vibratory and tandem ride-on rollers. Sourced directly from Wacker Neuson, this part meets the exact dimensional and material standards of the original, ensuring a correct, trouble-free installation. The covers an extensive range of RD27 configurations, including Pro, Basic, and T4F-compliant variants across both the RD27-100 and RD27-120 model lines. When you need a dependable replacement that installs without guesswork, this is the part to order.
Key Features
- OEM-Matched Bearing Housing Geometry — Manufactured to the original bore tolerances and mounting dimensions, ensuring the shaft seats correctly and rotates without misalignment-induced wear.
- Direct Bolt-In Replacement — Matches the original mounting pattern on RD27-100 and RD27-120 rollers, dropping into place without rework or shimming.
- Broad RD27 Series Coverage — Fits Pro, Basic, and T4F variants of both the RD27-100 and RD27-120, including hydrostatic vibratory roller and tandem roller configurations.
- Supports Smooth Drum and Drive Operation — A correctly seated pillow block keeps the shaft aligned under the heavy cyclic loads typical of compaction work; a worn or failed block leads to vibration, uneven compaction, and accelerated drivetrain damage.
- Genuine Wacker Neuson OEM Part — Carries the full Wacker Neuson OEM designation, so you know the material grade and construction match what came off the production line.
A pillow block is a housed bearing unit that supports a rotating shaft and holds it in precise alignment within the machine's frame. On a vibratory roller like the RD27 series, this component manages significant radial and axial loads generated during compaction cycles, keeping the drum or drive shaft running true. When a pillow block wears or fails, the shaft loses its support, leading to vibration, noise, and progressive damage to surrounding drivetrain components that can sideline the machine entirely.
