When it comes to linear motion, machine-tool applications are often the most demanding. Just consider how motion-controller manufacturers have improved their components in recent years with the latest processors to boost the precision of machine tools. Or consider how Heidenhain (maker of linear encoders) addresses the relatively small effect of thermal drift on mechanical components […]
Integrated measuring system with accuracy that rivals glass
IMS-I Integrated Measuring System From Rexroth: Precise, Robust, and Compact Fully integrated with accuracy that rivals a glass scale The newly enhanced IMS-I integrated measuring system from Rexroth achieves maximum linear motion positioning accuracy even in challenging work environments. The compact solution for ball and roller rail systems has an inductive design that offers repeatable […]
Electric current damage — How bearings fail Part 2 of 6
Recently we examined how corrosion contributes to bearing failure. Now we’ll examine electric current damage. Random electrical currents, which come from multiple sources, such as wiring, insulation, static electricity from operating equipment, and so on, will damage bearings. The damage usually appears on the surface of rings and rolling elements and is similar to that produced by electric […]
