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 […]
Thomson Lead Screws Drive Team 4 Element Robot Climber in FIRST Robotics Competition’s 2013
Team 4 Element, a team of high school students from Van Nuys, California, have designed, manufactured and assembled a robot climber to compete in the FIRST Robotics Competition (FRC) 2013 Ultimate Ascent game. The robot utilizes Thomson MTS Flange Mount Supernuts with stainless steel lead screws to drive the entire robot climber, with the goal […]
