GORILLA Drilling Motors
TM
6 3/4”, 7/8, 3.0 Stages
AXON offers a complete line of drilling motors from 1-11/16” to 11-1/4” (outer diameter). Each size range is offered
in a wide variety of lobe and stage configurations, operating temperatures, and standard or even-walled rubber.
Moreover, all GORILLA Drilling MotorsTM feature sealed, pressure-compensated, oil-lubricated bearing sections,
resulting in high load capacities via roller radial and roller thrust bearings. This maximizes life, improves power
transfer efficiency from the rotor/stator to the drill bit, and increases tool reliability.
Especially useful in hard rock drilling environments, the design allows for changing of the bearing stack
configuration by matching internal spacers to expected weight on bit.
