Domestic Dental Bearing Technology Breakthrough Breaks Import Dependence
May 07, 2026| May 8, 2026 Industry News
Driven by the wave of domestic substitution in dental medical equipment, the field of micro high-speed bearings – the core component of dental handpieces – has seen a new market landscape. Jiangsu Luyue Bearing Manufacturing Co., Ltd. and its subsidiary Guoyang Precision Machinery (Wuxi) Co., Ltd. have independently developed a high-speed dental drill bearing series. With breakthroughs in both material science and precision manufacturing technology, they are reshaping the market pattern where 80% of high-end dental drill bearings previously relied on imports.
Dental handpieces are among the most commonly used devices in dental treatment. The micro bearings inside must operate at extreme speeds of 400,000 to 450,000 revolutions per minute (rpm) within a tiny space of only 3.175mm in diameter, while also meeting stringent requirements for vibration, noise, and resistance to high-temperature high-pressure sterilization.

The breakthrough progress of domestic companies in this field has attracted attention. Guoyang Precision Machinery's SR144TLZ series high-speed dental drill bearings adopt a hybrid ceramic design (stainless steel rings + silicon nitride ceramic balls). Test data shows that under 400,000 rpm operating conditions, the temperature rise is 30% lower than that of all-metal bearings, and the service life exceeds six months. The product has passed ISO 13485 (Medical devices quality management systems) certification and is compatible with major international dental handpiece brands. It has been successfully used in the replacement parts market for international brands such as Germany's KaVo, Japan's NSK, Austria's W&H, and Switzerland's Bien-Air.
A comparative test conducted by a top tier 3A dental hospital in Beijing between domestic and imported bearings showed that after four hours of continuous operation, the temperature rise of domestic hybrid ceramic bearings was 2-3°C lower than that of imported bearings, and the radial runout of the drill was reduced by 15%. With the popularization of micro dental technology and digital diagnosis and treatment, the next generation of dental drill bearings is moving toward higher speeds (500,000 rpm) and smaller sizes (2mm outer diameter). Meanwhile, innovative directions such as graphene lubrication technology and intelligent wear monitoring chips are also in the laboratory testing phase.
