Cratridge Rotor For Dental High Speed Handpiece

The dental handpiece movement is the core power component of a high-speed dental handpiece, responsible for converting energy into high-speed rotational motion of the handpiece head. Its key components include a turbine assembly (comprising turbine blades and a rotor), a high-precision bearing system, and a drive shaft. The turbine is driven by compressed air to rotate at high speed (with a rotational speed ranging from 300,000 to 500,000 revolutions per minute), the bearings ensure rotational stability, and the drive shaft connects to the handpiece head to transmit power. The movement must possess extremely high precision (with radial runout usually less than 0.01mm) and sterilization resistance (capable of withstanding high-temperature and high-pressure sterilization at 134°C). It directly affects the cutting efficiency of dental treatment, operational stability, and patient comfort, making it a crucial core component that determines the performance of the dental handpiece.
