Material compatibility and quality is paramount in all vacuum applications.
Carter’s specialist bearings for ultra-high vacuum have been specified and proven with great success in a variety of applications including nano-precision position manipulator equipment, multi-stage mechanical goniometers and thermal mass flow controllers. Designers can choose Carter vacuum compatible materials including stainless steel and ceramics with a number of cage options available including stainless steel, PTFE and PEEK, with ball separators and full complement construction. Silicon Nitride ceramic balls can be utilized to eliminate the use of liquid lubrication. Carter offers various bearing assemblies using the most advanced bearing steels and ceramic material combinations.
Carter UHV bearings can also non-magnetic and high temperature resistant. Our thin section products which are light in weight and save space, allowing designers to reduce the overall size of equipment. Carter offers special ultra-high vacuum greases and a choice of dry film lubricants which are vacuum compatible (such as molybdenum disulphide and tungsten disulphide), including the industry-leading Cobra Solid Lubricant dry film lubrication which is exclusive to Carter in the UK.
