Silicon nitride balls ideal for medical uses
Thomson has introduced a new family of balls made from silicon nitride that are ideal for a number of high precision medical and test applications, including dental drills and gauges
Guaranteed to meet ISO standards and manufactured in an ISO-9002/QS-9000 plant, this new line of precision ball products conforms to the standards of the American Bearing Manufacturers Association (ANSI/ABMA Std 10-1989).
When compared with steel balls, silicon nitride balls provide equipment and device designers a number of benefits, including: a 40% reduction in weight; up to double the material hardness for tight tolerances; a coefficient of thermal expansion that is 70% less than steel; and an operating temperature range up to 1800F.
In addition, Thomson silicon nitride balls are noncorrosive, antimagnetic and excel in low-noise, high-rigidity and high-load-carrying applications.
Furthermore, these balls can run dry in a vacuum environment and up to 500F without lubrication.
Thomson silicon nitride balls are available from 0.03125 to 1in.
Special sizes can be ordered in lot quantities.
