Rj Link gearboxes have a “Gravity Lubricating Process”, which means customers get a gearbox that runs smooth, and has an extended life.  Once the Gear-housing is filled with the recommended oil, and the unit is operating:

•  The lowest gear dips into the bath of oil lubricating the teeth.
•  Then with splashing action, and meshing of the Gear-teeth, oil is delivered into the troughs and upper components.
• Once in the troughs, the oil flows by gravity through the passages, thus, lubricating the bearings, seals, etc.
• The oil passes through, and returns to the sump of the unit.
•  Cycle is complete
