Bomag 05740977 Spacer Disk

The Bomag 05740977 Spacer Disk is a genuine OEM component designed for Bomag tandem rollers across the BW 100, BW 115, BW 120, BW 125, and BW 131 series. Sourced directly from Bomag, this spacer disk delivers the precise dimensional tolerancing required to maintain correct component spacing and alignment within the drivetrain or drum assembly. Compatible models include the BW 100 AD-4, BW 100 AC-4, BW 115 AC-3, BW 115 AD-3, BW 120 AD-4, BW 120 AC-4, BW 120 AD-5, BW 120 AC-5, BW 120 SL-5, BW 125 AD-4, BW 125 AC-4, BW 131 AD-5, BW 131 ACW-5, and additional variants including the BW 120 AD-5 CC and BW 120 SLC-5. As a genuine OEM part, part number 05740977 matches the original specification exactly, so it installs directly without modification.

Key Features

• OEM Dimensional Accuracy — manufactured to Bomag's original thickness and diameter tolerances, ensuring the correct stack spacing that keeps rotating and sliding components operating within spec
• Drop-In Replacement — this spacer disk matches the original mounting interface on covered BW-series tandem rollers, slotting into position without rework or shimming
• Broad Tandem Roller Coverage — fits BW 100, BW 115, BW 120, BW 125, and BW 131 tandem rollers across the -3, -4, and -5 generation lines, including AC, AD, SL, SLC, SL-5, and ACW-5 variants
• Protects Adjacent Components — correct spacing prevents metal-to-metal contact between adjoining parts, reducing wear on bearings, shafts, and housings that rely on this disk for proper load distribution
• Genuine Bomag OEM Part — supplied as an authentic Bomag component, identical in material and geometry to what left the factory, giving you confidence that fit and function match the original build

A spacer disk is a precision-machined flat component used to set and maintain the correct axial gap between two adjoining parts — such as gears, bearings, drums, or shaft-mounted assemblies. By holding components at the intended separation, it ensures load is distributed evenly and prevents unwanted lateral movement or thrust that would accelerate wear. When a spacer disk wears thin, becomes damaged, or goes missing, the parts around it can shift out of alignment, leading to premature bearing failure, vibration, or accelerated wear on mating surfaces — all of which affect the smooth, consistent compaction performance that Bomag BW-series tandem rollers are built to deliver.
