The Bomag 05521805 Shim is a genuine OEM component designed for a broad range of Bomag single drum rollers, walk-behind and light rollers, and trench compactors, including the BW 211 D-5, BW 177 D-50, BW 179 DH-4, BW 60 S, BW 75 S-2, BW 90 S, BW 35, and BW 35 W, among many others. Sourced directly from Bomag, this shim meets the exact dimensional and material specifications of the original part it replaces. It installs without modification, preserving the precise clearances and alignment tolerances critical to correct drivetrain and assembly function. Buyers can order with confidence knowing part number 05521805 is the correct factory-specification shim for their machine.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to Bomag's exact thickness and material tolerances, ensuring correct load distribution and bearing clearance for this shim application.
- Drop-In Replacement — Matches the original mounting geometry exactly, seating cleanly into the same position as the factory shim with no rework or shimming adjustments needed.
- Broad Fitment Coverage — Compatible with a wide range of Bomag equipment, including BW 211-series and BW 177-series single drum rollers across multiple generations, BW 60 S, BW 65 S, BW 75 S, BW 90 S, and BW 6-series walk-behind rollers, and BW 35 and BW 35 W trench compactors.
- Preserves Assembly Alignment — A correctly fitted shim maintains proper spacing between components, preventing premature wear on adjacent bearings, shafts, and housings that results from even slight misalignment.
- Long-Term Serviceability — Using the correct OEM shim during reassembly protects the integrity of the surrounding drivetrain components and avoids costly rework caused by incorrect spacing.
A shim is a precisely machined spacer used to set and maintain exact clearances between moving or load-bearing components within a machine assembly. In compaction equipment like Bomag rollers and trench compactors, shims are critical for controlling the axial and radial play of shafts, bearings, and gears — keeping everything running true and preventing metal-to-metal contact where tight tolerances are required. When a shim wears, deforms, or is installed at the wrong thickness, it can lead to vibration, accelerated bearing wear, and eventual mechanical failure of the surrounding assembly.
