Description
Overview:
The Feather Key for Benford/Terex MBR71 Roller (MPN MS140-42) is a genuine Terex OEM component used to lock a hub to a shaft and transmit torque without slip. Manufactured from durable steel, it sits in the keyway to prevent relative movement between mating parts, helping maintain alignment and smooth operation under vibration. Designed for the Benford/Terex MBR71 family, it supports drive and ancillary assemblies where a secure shaft-hub connection is required. Its OEM dimensions and finish help ensure a precise fit in the original keyway, reducing the risk of fretting and wear. Suitable for tradespeople and DIY users carrying out maintenance or rebuilds on compact rollers such as the MBR71 or 1-71, it helps restore reliability with minimal downtime.
