Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the exact 18x44x0.5mm profile, ensuring correct load distribution and seating on mating surfaces.
- Drop-In Installation — Matches the original mounting interface on RAMMAX roller assemblies with no reworking of hardware or mating components.
- Confirmed Fitment — Compatible with RW1404, RW1404MR, and RW1504HF (up to S/N 1534188) RAMMAX walk-behind rollers.
- Correct Clamping Load — The precise thickness and outer diameter maintain proper bolt preload and joint integrity, preventing fastener loosening under vibration.
- Serial Number Specific — Fitment ranges are defined by Multiquip OEM data, so you get the right washer for your machine's build specification.
A washer at this specification serves as a load-distributing interface between a fastener and the surface it secures, spreading clamping force evenly to protect mating components from damage and prevent the fastener from pulling through or loosening under operational stress. On a vibratory roller like the RAMMAX RW series, hardware joints are subject to continuous vibration, making correct washer dimensions critical to maintaining secure assemblies throughout the compaction cycle. Using an incorrectly sized or worn washer can lead to fastener migration, uneven clamping, and accelerated wear on surrounding components.
