Key Features
- Genuine OEM Construction — manufactured to Bomag's original design tolerances, ensuring the supporting plate matches the structural load and mounting requirements of the original component
- Direct Replacement Fit — engineered to drop into the existing mounting position on BW 138 AD and BW 135 AD tandem rollers without modification
- Confirmed Tandem Roller Compatibility — verified fitment for the BW 138 AD and BW 135 AD, covering both models in this tandem roller lineup
- Structural Integrity Restored — a properly functioning supporting plate maintains correct component alignment and load distribution; a worn or failed plate can compromise the stability of the assembly it supports
- Exact Part Number Traceability — ordering by Bomag part number 78040504 confirms you are receiving the correct plate for your machine, eliminating the risk of mismatched parts during service
The supporting plate is a structural component that provides a stable mounting surface and load-bearing foundation within the roller's assembly. It holds adjacent components in correct alignment during operation, ensuring that vibration, weight, and mechanical forces are distributed as designed. When a supporting plate becomes cracked, worn, or deformed, surrounding components can shift out of position, leading to accelerated wear, assembly instability, and potential mechanical failure that extends service time and increases repair costs.
