Chemola™ Desco Open Gear Lube

Rack and Pinion Lubricant


Chemola™ Desco Open Gear Lube is a polymer base gear lubricant used where equipment is subjected to extremely heavy loading and may be subjected to water. This makes it a fine choice for the legs of jack-up rigs. It has a tackiness that makes it stick well to both wet or dry surfaces. It does not melt and is extremely water resistant. It has molybdenum disulfide and other extreme pressure additives to withstand extreme pressure in slow moving, highly loaded gears.

Recommended Uses
King pins, ball joints, chassis, universal joints, fifth wheels and Open gearing, slides, sprockets, jack-up rig legs, gear boxes and other gearing exposed to corrosion or adverse atmospheric conditions.
