The Multiquip 951402030 Key 10 x 8 x 28 is a genuine OEM woodruff/parallel key designed for the R-400G roller. This small but critical component ensures proper torque transmission between rotating shafts and mating hubs, maintaining precise alignment under load. Sourced directly from Multiquip, 951402030 meets the exact dimensional tolerances required for correct installation on R-400G equipment. When you need a like-for-like replacement, this is the part to order.
Key Features
- OEM-Spec Dimensional Tolerancing — Manufactured to the exact 10 x 8 x 28 mm profile required for secure shaft-to-hub engagement with no slop or misalignment.
- Direct Drop-In Replacement — Seats into the existing keyway on the R-400G without machining or modification, restoring the original drive connection.
- Confirmed R-400G Fitment — Verified for use on the Multiquip R-400G static roller, eliminating guesswork when ordering.
- Prevents Shaft Slippage Under Load — A correctly fitted key locks the shaft and hub together, ensuring full power transfer to the drum and preventing costly rotational slippage during compaction passes.
- Genuine Multiquip OEM Part — Supplied as an original component, not an approximation, so material hardness and shear strength match what the machine was built with.
A shaft key is a small, precision-machined component that fits into a machined slot — called a keyway — cut into both a rotating shaft and its mating hub or gear. Its job is to lock those two parts together rotationally so that torque is transferred from one to the other without slipping. On the R-400G roller, this means drive power reaches the drum reliably and consistently. When a key shears, wears, or goes missing, the shaft and hub spin independently, resulting in loss of drive, audible rattling, and accelerating wear to the keyway itself — making prompt replacement essential to avoid more extensive damage.
