How to Successfully Design a Maintenance

When using a metal bushing, you must use grease in order to keep the bearing pivot moving freely, and by doing this you are also protecting the shaft and housing from corrosion. However, there are downsides to this method. Dirt that is present in the environment sticks to the grease like a magnet, and since most end users don’t perform maintenance on their units as much as they should, the joint will most likely run on “dirty” grease (pictured left). A joint running in that condition is problematic since it causes excess wear on the shaft and bushing, eventually resulting in a premature failure of the joint.
