The Bomag 05566191 Bearing Bush is a genuine OEM component designed for Bomag BW 100, BW 120, BW 125, BW 135, and BW 138 series tandem rollers. Sourced directly from Bomag, this bearing bush delivers the precise dimensional tolerances and material grade required for correct operation in these machines. Confirmed fitment covers the BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, BW 120 AC-4, BW 120 AD-4, BW 125 AD-4, BW 125 AC-4, BW 138 AC-5, BW 138 AD-5, and BW 135 AD-5 tandem rollers. As a genuine OEM part, it meets the original design specification and slots in without modification to the existing assembly.
Key Features
- Genuine OEM Material Grade — manufactured to Bomag's original bush specification, delivering the correct bore tolerance and surface hardness for consistent load-bearing performance
- Direct Drop-In Replacement — engineered to the same dimensions as the original, this bearing bush seats correctly in the existing housing with no rework required
- Broad Tandem Roller Coverage — fits BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, BW 120 AC-4, BW 125 AD-4, BW 125 AC-4, BW 138 AC-5, BW 138 AD-5, and BW 135 AD-5 tandem rollers
- Sustained Smooth Articulation — a correctly fitted bearing bush maintains proper pivot movement and reduces metal-to-metal contact, preserving steering response and drum tracking on the finished mat
- Verified by Part Number — order with confidence using part number 05566191, cross-referenced against Bomag's OEM catalog for these tandem roller models
A bearing bush is a plain cylindrical sleeve fitted between two moving or load-bearing components — typically at a pivot, hinge, or articulation joint — to reduce friction and absorb wear. In a tandem roller, bearing bushes are commonly found at steering articulation points and drum pivot locations, where they carry lateral and radial loads during compaction passes. When a bearing bush wears thin or seizes, it allows metal surfaces to contact directly, leading to play in the joint, uneven drum behavior, and accelerated damage to surrounding components.
