- Thermal and Vibration Protection — maintains effective insulation between components, preventing heat transfer and damping operational vibration that can accelerate wear on surrounding parts
- Verified Bomag Part Number — listed under part number 78040405, eliminating guesswork and reducing the risk of ordering an incompatible component
An insulating mat serves as a protective barrier between heat-generating or vibration-producing components and adjacent assemblies within the machine. In tandem rollers like the BW 100 and BW 120 series, this mat helps prevent excessive heat transfer and mechanical vibration from degrading nearby components, wiring, or structural elements. When an insulating mat deteriorates or is missing entirely, surrounding parts are exposed to conditions they were not designed to handle, leading to accelerated wear and potential operational issues.
