The Bomag 05521225 Supporting Disc is a genuine OEM component designed for a wide range of Bomag walk-behind and light rollers, cold milling machines, vibratory plates, and trench compactors. Sourced directly from Bomag, this supporting disc delivers an exact match to the original specification, ensuring correct installation without guesswork. Confirmed fitment includes walk-behind and light rollers such as the BW 55 E, BW 60 S, BW 65 S, BW 65 S-2, BW 65 HS, BW 71 E, BW 71 E-2, BW 71 EHB-2, BW 75 E, BW 75 S, BW 75 S-2, and BW 90 S, cold milling machines including the BM 500/15 Stage V, BM 500/15-2, BM 600/15 Stage V, and BM 600/15-2, vibratory plates BP 10/36 and BP 15/45, and trench compactors BW 35 and BW 35 W. As a genuine Bomag part, this supporting disc meets every dimensional and material standard of the original component it replaces.
Key Features
- Genuine OEM Construction — manufactured to Bomag's exact dimensional and material standards, ensuring the same load-bearing performance and service life as the original supporting disc.
- Direct-Fit Replacement — matches the original mounting interface and disc geometry for a straightforward drop-in installation on all compatible machines.
- Broad Verified Fitment — confirmed for Bomag walk-behind and light rollers including the BW 55 E and BW 65 S series, cold milling machines including the BM 500/15 Stage V and BM 600/15-2, vibratory plates BP 10/36 and BP 15/45, and trench compactors BW 35 and BW 35 W.
- Structural Integrity Maintained — a correctly fitted supporting disc holds rotating or reciprocating assemblies in proper alignment; a worn or missing disc accelerates bearing wear and causes vibration irregularities throughout the drivetrain.
- Accurate Part Number — order with confidence using Bomag part number 05521225, cross-referenced to the machines listed above to eliminate the risk of ordering the wrong component.
A supporting disc serves as a precision locating and load-distributing element within a mechanical assembly, holding adjacent rotating or sliding components in their correct axial position. By maintaining proper alignment, it prevents excessive side loading on bearings and shafts, which is critical to smooth, consistent machine operation. When a supporting disc becomes worn, cracked, or missing, surrounding components lose their precise positioning, leading to accelerated wear, vibration, and potential damage to more costly drivetrain parts.
