The Multiquip 57191 Nut Slotted Round RW-1800 is a genuine OEM component designed for RW1810 RAMMAX rollers. Sourced directly from Multiquip, this replacement nut is built to the same specifications as the original hardware installed at the factory. Verified fitment on RW1810 series rollers means you can order with confidence and get your machine back to work without guesswork.
Key Features
- Genuine OEM Hardware Grade — Manufactured to the exact thread form, slot geometry, and material hardness required for this application — not a generic fastener substitute.
- Direct Drop-In Replacement — Matches the original part profile and thread specification, so installation seats correctly without reworking the mating components.
- Confirmed RW1810 Fitment — Designed specifically for the RW1810 RAMMAX roller platform; verify your model before ordering.
- Structural Integrity Under Load — A properly torqued slotted round nut maintains critical clamping force on rotating or load-bearing assemblies; a worn or missing nut risks loosening under vibration and cyclic loading.
- Cotter Pin Retention Compatibility — The slotted profile accepts a cotter pin or safety wire, providing a positive locking feature that prevents unintended loosening during operation.
A slotted round nut is a precision fastener used to secure rotating shafts, spindles, or bearing assemblies to a set preload. The slots cut into the nut face allow a cotter pin or safety wire to pass through a drilled hole in the mating shaft, locking the nut in position against vibration and dynamic loads. When a slotted nut becomes damaged, corroded, or lost, the assembly it secures can work loose, leading to accelerated bearing wear, misalignment, or component separation. Using the correct OEM replacement ensures the locking feature functions as intended and the assembly stays properly preloaded through the full operating cycle.
