Dental Handpiece Repair Parts & Tools
About Turbine Cartridges
Turbine cartridges (rotors) are the engine of the air-driven highspeed dental handpiece. The key components are
- Spindle/chuck (collet) assembly
- Impeller
- Bearings
Most also include other hardware, such as
- O-ring
- Slinger
- Washer
Autochuck is another name for the push button spindle/chuck (collet) assembly which holds the dental bur and onto which the other components of the turbine cartridge (e.g. bearings, impeller) are attached or pressed. The ISO maximum specification for concentricity (run-out) is 0.0012 in. / 0.03 mm.
Two common autochuck designs are clamp-pad and wedge.
Actuator
The button (A) that extends from the back of the autochuck. When the button on the end cap of a dental handpiece is pressed, it pushes down on the actuator which opens the chuck and allows the bur to be inserted or removed.
