Quality bearings are the foundation of a high-precision machine. Small-sized bearings fit any type of equipment from high-end machines, and high-powered industrial robots to very simple products like miniature fans or a child’s toy

We supply high precision Miniature / Small size Ball bearings for Dental rotating instruments which run your tolls smoothly as low-speed contra-angles also for High-Speed Dental Turbines

The precision of the ball bearing is measured in line pairs per inch (LPI). The higher the LPI, the better the bearing. There’s more to it than just LPI though. It also matters how far apart the races are spaced, and how round the balls are. The bearings can be single-direction or double-direction.

Ball bearings are one of the most important components in any Dental drill. We offer a wide range of ball bearings with four main parts: two rings, the rolling elements, and the ball separator. Radial ball bearings and angular contact bearings have an inner and outer ring with heavy and light-duty, sealed and shielded, miniature and small-sized ball bearing for both low and high speeds.

A lot of visitors visiting our site see that our dental turbines are manufactured with Ceramic Ball Bearings and we would like to answer the question about Steel Ball Bearings vs. Ceramic Ball Bearings.

First of all both types of High-Speed Ball Bearings are used on Dental Turbines because their rpm(rotation per minute) is 400 000 and just high-quality Dental High-Speed Bearings can resist 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 factors for 25 years.

Let’s see what the fundamental difference between these two types of ball bearings and you will do a conclusion yourself if it is worth making savings on Steel Ball Bearings or not and why it’s 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 fresas dentales manufactured by Mk-Dent Dental have common features:

All dental Rotors are assembled with German MYONIC Angular Ceramic Ball Bearings which have high resistance and have the best smooth ceramic ball bearings which increase the life of the bearing. Bearing sleeves are made of stainless steel, which allows sterilizing tips in autoclaves.

Thus, whatever fresas dentales you choose on our website, will serve you long and faithful service, and you will only be happy to work with them.
