Gear oils based on selected paraffinic mineral base oils. Contains synergistic additives that guarantee outstanding wear protection performance of these new high-tech gear oils. Highly effective tribo-protection layers reliably protect wetted machine components against wear. This new additive technology is also referred to as a smoothing PD (plastic deformation) reaction mechanism. The additives in these gear oils have a noticeable smoothing effect on surface roughnes. Can be used both in new gearboxes (spur, bevel, planetary and worm gears) to reduce friction, wear and noise in extreme conditions as well as in pre-damaged gearboxes and machine components to increase service life.
