Ceramic balls are available in many compositions and formulations. Ceramic balls resist corrosion and abrasion very well—features that make ceramic balls great for flow control and bearing applications.
Because their polished surfaces provide an extremely good seal, glass balls are ideal for check valves in food processing, pharmaceutical, and photographic processing equipment.
Hollow balls are used in applications where either flotation or weight savings are required. Ball transfer units are used primarily in aircraft transport cargo rolling decks. The rolling elements can be either hollow balls or standard balls.
ITI can manufacture balls from any workable material; including: aluminum, brass, bronze, cobalt, M-50 high speed steel, tantalum, and titanium.
Plastic balls are ideal for light-load bearings and flow control applications. Because they are quiet, plastic balls are often used in office furniture, medical products, and similar applications.
Nickel alloy balls such as Inconel, Monel 400 and K 500 Monel, and Hastelloy® balls are often used when the corrosion or high temperature requirements are too severe for the common stainless steels available.
Balls are available in virtually every grade of stainless steel: 300 series, 400 series and specialized / custom grades. Large diameter stainless steel or chrome alloy balls available from stock or made to order. Reference our material charts to determine which variation offers the appropriate corrosion resistance and hardness for your application.
Tungsten carbide (TC) balls are used where extreme hardness and wear resistance is required. TC balls are not only used in coining and ballizing (ball burnishing) processes but also for gauging / checking tools. They are available in fractional and decimal sizes.
