Rex Roller Locknut

This is a heavy-duty roller locknut designed to secure the drum support roller axle on the pedestals of rear discharge concrete mixers. Its nylon insert provides prevailing torque to resist loosening from the intense vibration and constant rotation of the mixer drum, ensuring the roller assembly remains safely affixed. This nut is a critical component for routine maintenance and is typically replaced when servicing or replacing drum rollers. It is compatible with roller assemblies from several major OEMs, including McNeilus, Con-Tech, and Kimble.
