YDTech® manufacturer of precision high speed dental drill ball bearings! supplier of micro deep groove ball miniature bearings for dental handpieces in china.
our high speed ball bearing for dental hand piece can achieve a speed of 400,000 spins per minute and offer 6 months clinical life, our speed dental drill ball bearings ave been selected as the support parts and components to products by major medical equipment manufacturers to replace dental hand pieces bearings by europe, USA, canada etc.
we have super precision miniature bearings for most dental/medical applications. these dental bearings are of the highest quality and precision with operational tolerances exceeding. our dental bearings are the first high-speed, self-lubricating dental bearings to combine superior wear resistance with exceptional autoclave resistance. these new premium bearings raise handpiece standards: smoother operation, longer life and maintenance-free performance.
With advances in bearing design, dental hand piece bearings have evolved to give extended life and performance possibilities. with the increasingly economic options for ceramic components, many dental designs have ceramic elements although this is by no means the ultimate answer to all dental requirements
we has developed a honing technique which improves the surface finish and the relative roundness of the bearing's inner and outer raceways, resulting in consistently higher speeds over the lifetime of the handpiece.
dental bearings can make a real difference to the performance of your high speed handpiece. we have improved the material quality, surface finish and the design of the bearing shields to produce the most efficient dental bearing yet.

dental bearings operate in what must be one of the most extreme environments imaginable. Repeated sterilisation, loss of lubricant and the effects of operating debris often cause them to fail prematurely. our products improvement and reliability programme enables handpiece manufacturers to significantly increase their warranties.
our dental bearings can lower patient anxiety by reducing the noise generated by compressed air passing through the bearing. Using a compact, integral shield design and fine tolerances results in a much more comfortable operating mode.
our dental bearings last up to four times longer than traditional bearings due to a unique combination of features. The bearings have a 60% smaller critical gap between the integral shield and the bearing inner ring compared to conventional designs. We've also improved the shield design to effectively retain lubricant, overcome the risk of shield ejection and prevent contamination from operating debris.
