Bearing for dental hand-piece

Dentistry has soared in China in recent years, along with mouth health and tooth beautifying culture attracting more and more attentions. According to the forecasting of China Sadi, the market for oral health equipment and relevant products and services will break through four hundred billion Yuan by 2020. The oral health market is a Blue Ocean Market with enormous development potential.

Though it might be a minor matter merely, the oral disease, with high incidence rate, causes many troubles to people. Such as saprodontia (generally known as decayed tooth). According to the 3rd Epidemiological Investigation on Oral Health in China, the prevalence rate of saprodontia in China is about 50% and averagely each one has 2.5 decayed teeth. To be specific, the prevalence rate of saprodontia for the people aging from 35 to 44 years is 88.1%, and the people aging from 65 to 74 is 98.4%. As the coming of aging society, the dental health problem will be further highlighted.

Given the great demands for oral caring personnel and the strong profitability of oral health medical institutions, more and more social capitals swarm into the oral health field. In the meantime, the further deepening of medical and health system reform brings new development opportunities for private oral health hospitals. Most oral health brands and organizations in the market, such as ARRAIL, KEER and Beichen, adopt advanced foreign dental diagnosis and treatment equipment sets and caring methods.

The focus here is the dedicated equipment for dentistry - dental hand-piece. In addition to NSK dental hand-piece which is the most commonly used in current Chinese market, other popular brands are as follows:

Dental hand-piece brands at home and abroad

Domestic brands: JINME, XIBEI, ZHUOMUNIAO and COXO

Foreign brands: KaVo, Sirona, NSK and W&H

NSK was originally a bearing company who has focused on bearing industry instead of dental hand-piece R&D. It can be said, NSK has great bearings, while its body mechanics and comfort level are far away from Chinese style. At present where many domestic manufacturers import NSK bearings, let alone other important parts, the difference is greatly narrowed down to the processing technique. Therefore, if a manufacturer, no matter at home or abroad, plans to produce a dental hand-piece of high quality, it will face the biggest problem - choose a suitable bearing. Internal techniques may be researched/developed and explored by the manufacturer itself, however, the core part of dental hand-piece, bearing, is the most worried problem of all manufacturers.

With foresight, SWC has researched and developed the dedicated bearing SR144 TLNZ for dental hand-piece since 2010. After about 10 years of endeavors, the bearing solves such quality problems as retaining appliance, steel ball and noise. This is an example to illustrate the precision and technique level of 420,000: a high-speed dental hand-piece rotates 420,000 times per minute, namely 7,000 times per second. For common explanation, the noise is reduced by 1dB for the precision improvement of 0.01mm. The 10dB reduction is the best reward to the whole R&D team.

No pains, no gains. In front of the gate of dental hand-piece market, SWC is ready to fight for a bright future!
