Ceramic Insert Bearings (UC Type)

V W Impex offers UC type Ceramic Insert Bearings. These are made entirely of ceramic material and are superior to common steel insert bearings in many ways. Ceramic is the perfect material for any application seeking to achieve higher RPM, reduce overall weight or for extremely harsh environments where high temperatures and corrosive substances are present. Applications such as cryopumps, medical devices, semiconductors, machine tools, turbine flow meters, food processing equipment, robotics and optics. Ceramic materials commonly used for bearings are Silicon Nitride (Si3N4), Zirconia Oxide (ZrO2), Alumina Oxide (Al2O3) or Silicon Carbide (SiC). Because ceramic is a glass like surface it has an extremely low coefficient of friction and is ideal for applications seeking to reduce friction. Ceramic balls require less lubricant and have a greater hardness than steel balls, which will contribute to increased bearing life. Thermal properties are better than steel balls resulting in less heat generation at high speeds. Full ceramic bearings can have a retainer or full complement of balls, retainer materials used are PEEK and PTFE. Full ceramic insert bearings can continue to operate under extremely high temperatures and are capable of operating up to 1800°F. Ceramic is much lighter than steel and many bearings are 1/3 the weight of a comparable steel bearing. Full ceramic insert bearings are highly corrosion resistant and will stand up to most common acids, they will not corrode in exposure to water or salt water.

V W Impex is an established name in the field of bearings as an importer, exporter and supplier of eccentric bearings, precision bearings, linear motion guides and rails, ceramic bearings, plastic bearings, and above all Nilos rings. Backed by an experience in this field of over two decades, the company imports directly from manufacturers in Germany, England and USA, a range of hard-to-find bearings not available in the Indian market.
