Self-lubricating sliding components with drilling holes/notches, in which solid lubricant is stored. During usage, this solid lubricant is continuously released onto the sliding surface, producing a continuous lubricating film that keeps both metal parts from touching each other.
USAGE CHARACTERISTICS OF WABRO®
For all instances where high strain and low friction velocities happen. WABRO® – maintenance-free sliding components are shipped ready-to-install on customer request.
MECHANISM OF WABRO®
WABRO® – maintenance-free sliding components are self-lubricating Elements for medium to high strains and low friction verlocities. They are made out of a carrier material which is chosen depending on application. Solid lubricant is applied to the carrier material using various techniques. The solid lubricant is injected into the notches or drilling holes and is stored there.
This solid lubricant produces a continouos and stable film on both sliding surfaces and thus fills in the roughness depth of the materials surface. A sliding layer keeps the metal surfaces of both components from touching each other, preventing a "stick-slip-effect". During operation, the sliding film is continuously replenished by the lubricant coming out of the notches or drilling holes. Any occuring foreign matter can be sucked up by the lubricant pockets.
ADVANTAGES OF WABRO®
The advantages of WABRO® – maintenance-free sliding components are as follows:
an almost indestructible solid lubricant film on the friction surfaces that doesn't break even under high strains
no maintenance and therefore especially beneficial in inaccessible places
flawless lubrication even in higher temperatures
constant coefficient of friction in motion and resting state
very suitable for mounting by plain bearing in industrial fluids, fresh and marine water, since solid lubricant can't be washed out
suitable for axial and rotary movement
flawless lubricating effect during intermittent usage
