Special applications have very demanding conditions which require bearings to deliver expectional capabilities.
At the other end of the spectrum, there are large bore bearings with an outside diameter up to 6 meters that weigh more than 15 tons and are used in applicaitons including large tunnel boring machines.
These extremely high speeds together with absolute precision virtually eliminate vibrations in dental drills. In addition to being a fascinating aspect from a technical perspective, it should also be a relief to patients, who can rest assured that they will receive safe and quiet treatment.
(*1 nanometer is a thousand millionth of a meter).
High-precision bearings are also able to take extreme heat, operating in computer tomographs at temperatures of +300-500 °C / +572-932°F and in vacuum tubes with X-rays. By doing so, they help health care professionals provide modern day comprehensive check-ups.
