Heavy-Duty Steel Slides - SDC C-Shaped Linear Guides
Ways to Order
Steel C-shaped linear slides are heavy-duty linear guides built around the same precision ball cage and hardened steel rail technology used in the PBC Linear steel drawer slide family, but with one important difference: instead of telescoping outward like a full extension drawer slide, SDC Series slides keep an internal carriage captured inside a fixed C-shaped external rail. The internal carriage is the moving load-carrying member, while the ball cage is a separate component that holds the steel balls between the carriage and rail surfaces. As the carriage moves inside the rail, the ball cage floats between the two rolling surfaces and usually travels about half the carriage distance, keeping the balls spaced, aligned, and captured while they roll. This provides low-friction bearing action, load distribution, and guided motion with reduced wear.
Integrated mechanical end stops control travel within the rail length, helping protect internal components while keeping motion contained inside a fixed rail envelope. C-shaped rail geometry also allows multiple internal carriages to run on a single rail, supporting modular high-capacity motion systems. SDC Series slides are available with single- and double-direction stroke options, strokes up to 1310mm, rail lengths from 130mm to 1970mm, and load capacities up to 65272N. Common uses include heavy industrial platforms, large access panels, robotics staging systems, machine access systems, and other rugged applications where high load capacity, durability, and contained linear motion are required. The enclosed C-shaped geometry helps protect internal components from debris while maintaining consistent, guided motion.
