What does “lubrication-free” mean?

You are here:

Many manufacturers declare their products to be “maintenance-free”. This usually means that the respective bearing is delivered with initial lubrication. As long as the lubrication is intact, no maintenance of any kind is needed. iglidur plastics, in contrast, do not have a film of lubrication and no reservoir of grease that is used up. The homogeneous structure of the plain bearing’s material ensures that wear is mostly linear without any surprises or maintenance intervals that have to be adhered to.
