1.Clean Head System The patented NSK Clean Head System is a special mechanism designed to automatically
prevent the entry of oral fluids and other contaminants into the handpiece head prolonging the life of the bearings.
2. Excellent Stability Ceramic Bearings are 25% harder than conventional steel bearings but are only half the weight.
Because frictional wear between the ball bearings and the bearing retainer is significantly reduced the efficiency and
durability is significantly increased.
