Ceramic Balls Information
Ceramic balls are spherical, rolling elements that provide higher stiffness, lower thermal expansion, lighter weight, increased corrosion resistance, and higher electrical resistance than steel balls. They are made from a variety of ceramic materials.
Applications for Ceramic Balls
The GlobalSpec SpecSearch database contains information about applications for ceramic balls, many of which are used as bearings. The following list provides some examples.
Ceramic aerospace bearingsare used in airframes as well as gyroscopes (gyros), navigation systems, flow meters, avionic instruments, and other aerospace parts.
Agitator ballshave suitable corrosion and density (weight) for agitation or mixing applications, such as the balls used in aerosol paint cans.
Ceramic automotive bearingsare used with seating tracks and seat slides, safety restraints and seatbelt locking mechanisms, airbags, constant velocity (CV) joints, double offset joints, tripod joints, cross groove joints, spindle bearings, and many other systems.
Conveyors ball sare used in conveyors, ball transfer units, roller table, casters, roller or lazy Susan applications.
Spring loaded ballsare used in quick disconnect couplings or snap on fasteners and fastening systems. Socket wrenches often use this type of fastening mechanism to hold onto the socket.
Ceramic balls are also used in float or level sensing, flow metering, gaging or alignment, valves, sprayers and pumps, and pollution or vapor control systems.
