Material Notes:
FeaturesChevron Open Gear Lubricants are black, viscous lubricants formulated with an asphaltic base and diluted with a nonchlorinated solvent for easy application by hand or through automatic lubrication systems.They provide a high film strength coating on gear teeth to minimize wear.Chevron Open Gear Lubricants are designed to provide tacky, tenacious lubricant films on open gears operating under severe shock load conditions. Chevron Open Gear Lubricants contain a nonchlorinated diluent that eases the application of these lubricants onto the gears. The diluent then evaporates, leaving a tacky lubricant film on the gear teeth.They can also be used to lubricate chains, sprockets, wire rope, and cables. When used as a cable coating, the diluent allows the lubricant to penetrate into the core, thus carrying the lubricant into the individual strands and minimizes wear as the cable is run through sheaves or onto a winch drum.ApplicationsChevron Open Gear Lubricants are recommended for all types of open gears, wire ropes, and cables. They can be applied by brush, swab, spray gun, or by automatic lubrication systems.All grades provide lubrication for mining equipment including:girth and pinion gears on rod and ball millsrack and pinion gears on shovel dipsticksand swing and pinion gears on top of the lower frame of shovels and draglines, which are sometimes served with an automatic lubrication system.Chevron Open Gear Lubricants meet Bucyrus-Erie and P&H requirements for electric shovels and draglines.
