Dental Cartridge Of High Speed Handpiece Air Turbine Rotor Spare Parts

Product Description:

A dental cartridge, also known as a turbine cartridge or rotor cartridge, is a crucial component of a high-speed dental handpiece. The high-speed handpiece is a dental instrument used for cutting and drilling during various dental procedures.

The dental cartridge is a small, replaceable module that houses the turbine, bearings, and other mechanical components responsible for driving the cutting tool (bur) at high speeds. It is typically made of stainless steel and is designed to withstand the rigors of high-speed operation.


  1. Turbine: The turbine is the main component of the cartridge responsible for generating rotational motion. It is usually driven by compressed air or, in some cases, an electric motor. The turbine rotates at high speeds, typically ranging from 300,000 to 400,000 revolutions per minute (RPM), to provide the cutting power required for dental procedures.

  2. Bearings: The cartridge contains precision bearings that support the turbine and ensure smooth rotation. These bearings are designed to reduce friction and allow the handpiece to operate quietly and efficiently. Common types of bearings used in dental cartridges include ceramic or stainless steel bearings.

  3. Chucking System: The cartridge incorporates a chucking system that securely holds the dental bur or tool in place. The chucking system allows for quick and easy bur changes during procedures.

  4. Water Spray: Many high-speed handpieces feature a water spray system that cools the bur and flushes away debris during use. The cartridge typically includes channels and nozzles to direct the water spray onto the bur, reducing heat buildup and improving visibility.

  5. Replaceability: Dental cartridges are designed to be easily replaceable. When a cartridge becomes worn, damaged, or needs maintenance, it can be removed from the handpiece and replaced with a new one. This allows for efficient and cost-effective maintenance of the handpiece.
