⚙️Product description:
Specifically designed for dental ultra-high-speed treatment scenarios, it is the core component that ensures the stable operation of dental drills and enhances the accuracy of treatments. It is suitable for high-precision operations such as preparing dental implant sockets and dental restoration.
⚙️Material and Structure:
Main Configuration: The inner and outer rings are made of high-precision stainless steel 440, which is highly resistant to corrosion and deformation, and is suitable for dental high-frequency, high-temperature, and high-pressure sterilization environments; The rolling elements are made of Si3N4 nitride silicon carbide beads, with low friction coefficient and high hardness (HRA 90+), effectively reducing wear and temperature rise during high-speed operation.
Auxiliary Structure: The cage is made of Torlon special polyamide material, which is resistant to high temperatures (long-term operation at 260℃) and anti-creep, ensuring structural stability during ultra-high-speed operation; The "Z" in the model represents a single-sided metal dust-proof cover, which can prevent moisture and debris from entering the bearing interior, extending the service life.

Ultra-high-speed Adaptability: The precision grade reaches ABEC-7, and the maximum rotational speed can reach 400,000 revolutions per minute. It fully meets the operation requirements of dental high-speed handpieces, and the radial runout during operation is ≤ 5 μm, ensuring precise operation.
Sterilization Resistance and Durability: It can withstand ≥ 200 cycles of high-temperature and high-pressure sterilization. After sterilization, the torque change rate is controlled within ±8% of the initial value. It has a long service life under normal working conditions, reducing the frequency of instrument maintenance.
Stable Temperature and Low Noise: The combination of ceramic beads and special retainers significantly reduces operating friction. The temperature rise at the highest rotational speed is ≤ 15℃. At the same time, it reduces instrument vibration and noise, enhancing the comfort of the doctor's operation and the patient's diagnosis and treatment experience.
