Ce să aleg? – Rulmenți Turbină Dentară Ceramici sau Oțel
A lot of visitors visiting our site see that Mk-Dent Dental Turbines are manufactured with Ceramic Ball Bearings and we would like to answer the question about Steell Ball Bearings vs. Ceramic Ball Bearings.
First of all this both types of High Speed Ball Bearings are used on Dental Turbines because their rpm(rotation per minute) are till 400 000 and just high quality Dental High Speed Bearings can resist on such speed and last long.
You will not see on Mk-Dent Dental Turbines steel ball bearings because the company has a serious authority as High Quality Manufacture of Dental Handpieces and people appreciation is one of the main factor for 25 years.
Let’s see what the fundamental difference between this two types of ball bearings and you will do conclusion yourself if it worth to make savings on Steel Ball Bearings or not and why its better to buy a Dental Drill with Ceramic Ball Bearings.
- Dental Steel ball bearings
Balls made of steel are used as rolling bodies.
When using metal in the production of bearings, it is rather difficult to obtain a perfectly smooth surface of the balls and minimize friction. All these factors significantly reduce the service life of steel bearings (this is undoubtedly a disadvantage). The advantage of such bearings is that there are much cheaper and need less care about them for cleaning and lubrication.
- Dental Ceramic Ball Bearings
As rolling elements in such bearings are used balls made of ceramic.
Bearings with ceramic balls are more durable and less noisy. The low coefficient of friction of ceramics increases the surface stability of the balls and increases the service life of the bearing as a whole. The density of ceramics is 40% less than the density of steel, which lowers the centrifugal load and the level of internal stress at high speeds of rotation.
Thus, Dental Handpieces with this type of bearings, compared with handpieces with steel bearings, are quieter and have a longer service life, but they are more expensive and need to be cleaned and lubricated after 2-3 hours of work.
Common to all bearings
In this case, all the ball bearings in the dental drills manufactured by Mk-Dent Dental have common features:
All dental Rotors are assembled with German MYONIC Angular Ceramic Ball Bearings which high resistance and have best smooth of ceramic ball which which increase the life of the bearing. Bearing sleeves are made of stainless steel, which allows sterilizing tips in autoclaves.
Thus, whatever dental drills you choose on our website, they will serve you a long and faithful service, and you will only be happy to work with them.
