All Dodge® E-Z-Kleen® and Ultra Kleen™ bearings include a housing groove to accept a snap-on polymer end cover. These durable covers are easy to install and each is provided with a drain hole to prevent moisture from collecting inside the cover. The snap-on style of end cover incorporates an additional lip on the mounting surface for a rigid fit within the housing. This tight fit creates a better seal prevents movement of the cover during operation and high pressure cleaning. Dodge® snap-on end covers provide positive sealing in wet environments and create safer working conditions by enclosing rotating shafts.
