High-Performance Dental Handpiece Bearings: Precision Engineered for Reliability

For dental handpiece manufacturers, repair technicians, and distributors, the bearing is the core of tool performance. したがって, our dental handpiece bearings are engineered to deliver a precise balance of ultra-high speed capability, minimal vibration, and long service life. 加えて, each component is manufactured under controlled clean production conditions. This ensures compliance with strict medical device industry standards.

主な特長

High Precision

Dental bearings require extremely tight tolerances. This ensures accurate positioning and stable operation of the dental bur at very high speeds.

加えて, dimensional accuracy typically exceeds ABEC-7 standards for high-speed instrument bearings.

さらに, a highly controlled surface finish and precise roundness of the inner and outer raceways improve consistency. 結果として, high-speed performance remains stable throughout the bearing’s service life.

High-Speed Capability

These bearings operate at extremely high rotational speeds. Typically, they reach 350,000 に 450,000 RPM under 200–250 KPa air pressure.

This makes them suitable for modern dental applications that demand fast and stable cutting performance.

Corrosion and Wear Resistance

The bearing rings are usually made from corrosion-resistant stainless steel. Meanwhile, the balls are made from silicon nitride ceramic (Si3N4).

Silicon nitride ceramic offers high hardness and strong wear resistance. 加えて, it has low thermal expansion and excellent corrosion resistance.

したがって, it performs well even in environments with limited lubrication.

Low Noise and Low Vibration

Compact dust cover designs help reduce contamination and noise. At the same time, tighter tolerances improve rotational stability.

加えて, the lightweight structure and self-lubricating properties significantly reduce vibration. 結果として, patient comfort is greatly improved during dental procedures.

Heat Resistance

High-speed rotation generates heat during operation. したがって, dental handpiece bearings use heat-resistant materials.

加えて, optimized structural design improves heat dissipation. This helps maintain stable performance under continuous use.

アプリケーション

High-Speed Air Turbine Handpieces

These are used for cavity preparation, crown shaping, and removal of old fillings.

Low-Speed Electric & Air-Driven Handpieces

These are suitable for polishing, finishing, and prophylaxis procedures.

Surgical Handpieces

These are widely used in implantology and oral surgery. In these applications, torque stability and reliability are critical.

Endodontic Handpieces

These are used for root canal treatment. Precision and smooth rotation are essential in this field.
