The Bomag 05585973 Spacer Ring is a genuine OEM component designed for BW 145, BW 177, and BW 179 series single drum rollers. Sourced directly from Bomag, this spacer ring matches the original part in material, dimensions, and fit — ensuring the assembly goes together exactly as it did from the factory. This part covers an extensive range of variants across the BW 145, BW 177, and BW 179 families, including D, DH, PDH, DHC, and PDHC configurations, as well as the C 825 C single drum roller.
Key Features
- Genuine OEM Precision — manufactured to Bomag's exact material and dimensional specifications, ensuring the spacer ring maintains correct component spacing and load distribution within the assembly
- Direct Drop-In Fitment — engineered to install in place of the original without machining, shimming, or adapting surrounding components
- Broad Model Coverage — fits a wide range of BW 145, BW 177, and BW 179 single drum rollers, including D, DH, PDH, DHC, and PDHC variants across the -3, -4, -40, -50, and USA-spec generations, as well as the C 825 C single drum roller
- Assembly Integrity — a correctly fitted spacer ring keeps mating components properly aligned and prevents premature wear caused by axial play or contact between parts that should not touch
- Verified Part Number — order with confidence using Bomag part number 05585973, cross-referenced to the fitment data for the machines listed above
A spacer ring is a precisely sized collar or sleeve placed between two components in a rotating or sliding assembly to maintain a fixed axial gap and prevent unintended metal-to-metal contact. In a single drum roller, spacer rings are commonly used in drum drive assemblies, bearing housings, and shaft arrangements to keep components correctly positioned under load and vibration. When a spacer ring wears, deforms, or is missing, adjacent components shift out of alignment, accelerating bearing wear, creating vibration, and potentially causing more serious structural damage to the assembly.
