Roller is a rotary body with screw blades and three integrated rollers that rotate continuously, minimizing surface area and assosiated friction, providing greater stability and reliability in the most harsh environments.

Rollers reduce the downhole torque typically experienced using fixed-blade stabilizers which have greater contact area with hole walls. Compared to standard stabilizer wth stationary blades, rollers decrease well damage in brittle formations. Rollers are also less subect to wear in abrasive formations compared to standard blades.
