UNASIS’s specialist bearings for ultra-high vacuums have been designed and proven with remarkable success in a variety of applications including nano-precision position manipulator equipment, thermal mass flow controllers, and multi-stage mechanical goniometers. Designers have the ability to choose UNASIS vacuum-compatible materials such as ceramics and stainless steels with a number of cage options available including PTFE and PEEK with ball separators and full complement construction. Silicon Nitride ceramic balls can be utilized to eradicate the use of liquid lubrication. UNASIS provides various bearing assembles using the most advanced bearing steel and ceramic material combinations.
UNASIS UHV bearings can also be made non-magnetic and high-temperature resistant. Our thin-section bearings are light in weight and save space which allows designers to reduce the overall size of equipment. UNASIS offer speciality ultra-high vacuum greases and a choice of dry film lubricants when required, which are vacuum compatible (such as molybdenum disulphide and tungsten disulphide), including the market leading Cobra Solid Lubricant dry fill lubrication which is exclusive to UNASIS within the UK.
