But if you’re designing a linear-motion system, you’ll have to consider structural support, guides, drives, seals, lubrication, and accessories between points A and B.

Linear actuators and oscillating systems constitute a vibrant area of research that bridges concepts in electromagnetism, mechanics and control engineering.

One of the most misunderstood principles regarding linear bearings is something called the 2:1 Ratio. Understanding it will help engineers avoid the problem of stick-slip.
