Rotary stroke bearings from Mahr provide high guiding accuracy for linear and rotary movements, with zero backlash and low friction for stick-slip-free movement. Applications include machine tool spindles and pick-and-place assembly robots. The high-precision units are used in measurement transducers, positioning units, centering and tilting tables, and in other modules that have an influence on the measuring result. The size and form accuracy (roundness and cylindricity) of the micro-finished running faces of shafts and bushings is less than 1/3 ISO standards; and only grade 5, sorting class P0 steel balls (DIN 5401 or ISO 3290) are used.

Researchers from Purdue University are studying the fundamental mechanisms behind a method that uses electrical fields to enhance ceramics-sintering processing, which could aid R&D of rechargeable lithium-ion batteries and fuel cells. The research also could shed light on a phenomenon called electromigration, which can affect the performance of electronic devices.
