These new antibacklash nuts last long with little maintenance. They use Haydon's self-lubricating polyacetal and rolled 303 stainless screw material to offer low drag torque and smooth operation for the life of the assembly, all on a single lubrication. They can even run dry with Haydon screws covered with the company's Black Ice™ PTFE coating process, which eliminates the usual flaking problems with other PTFE coatings. Haydon developed its own patent pending method for preloading the threaded-nut halves, maximizing system stiffness and reducing drag torque. Its design compensates for wear and eliminates lockup problems when traveling from worn to unworn areas of the screw. They can work with Haydon's current line of linear actuators or by themselves with Haydon's selection of lead screws.
In many engineering workplaces, there’s a generational conflict between recent engineering graduates and older, more experienced engineers. However, a recent study published in the psychology journal Cognition suggests that both may have something to learn from another group: 4 year olds.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
