Sliding Linear Guides

Sliding linear guides are simple systems designed to move objects in a straight line by allowing one surface to slide smoothly over another, like a drawer in a cabinet.
Here is the simple breakdown of what it does:
• Slides, Doesn't Roll: Unlike rolling guides that use balls or rollers, these systems rely purely on two surfaces rubbing (sliding) against each other.
• Relies on Lubrication: They must use grease, oil, or a slippery material like Teflon (PTFE) between the surfaces to reduce friction and prevent them from grinding together.
• Tough and Simple: They are extremely durable, inexpensive, and can handle massive impact forces (shock loads) better than systems with delicate rolling balls.
• Less Precise & Slower: They generally aren't as fast or as accurate as rolling guides due to the friction involved, but they are very reliable for tough industrial jobs.
In short, a sliding linear guide is a sturdy, simple track system that uses lubrication and sliding friction to move heavy machine parts smoothly in a straight line.
