Welcome to this installment of MC² on Linear Bearings & Linear Splines!
Recall that these linear-motion supports take the form of guide rails, slides, and ways … and include profile rails, linear bearings, guide wheels, slides, and plain-bearing systems that bear load while employing either sliding or rolling to allow translational motion. Typical designs pair rail or shaft with mating carriages or runner blocks.
You’ll find some resources on linear guides and slides to help design engineers choose from the vast array of these linear systems … and satisfy requirements for loading, stroke, speed, accuracy, and design life.
Also check out our library on preloading considerations and market-specific topics … including machine-tool applications and semiconductor manufacturing (where rolling linear guides abound); advanced medical applications (where square rails are common); and simpler machine axes (where forgiving slide designs maintain build ruggedness).
