HOW IT WORKS

Between unlubricated bearing surfaces, the solid lubricant has a smoothing effect (flow smoothing), filling the roughness valleys and coating them with a thin, hard, durable, and continuously renewing lubricating film.

With a recommended surface finish of the shaft (steel) of a roughness depth of Ra ≤ 0.8 and of the sliding bearing bore (bronze) of Ra ≤ 1.2, the micro-roughnesses are formed that are needed for the durability of the solid lubricant film.

During the running-in phase, the factory-applied break-in film prevents the surface peaks from pressing against each other or engaging into the recesses of the mating material.

The micro-wear generated by bearing operation (load and sliding speed) is pressed into the solid lubricant depots, whereby the lubricant released through displacement fills the micro-roughnesses.

The resulting solid lubricant film permanently separates the two sliding partners, with a low coefficient of friction, minimal wear, and a long service life.

Even under high static loads, the friction coefficient is significantly reduced at the moment of start-up, preventing dry running and seizure/welding.
