Full-extension linear slide SDS

drawerheavy-dutysteel

Overview
Full-extension drawer slides are telescoping linear rail assemblies built around a ball-cage slide mechanism that allows a load-bearing platform to travel outward to its full usable length, exposing a supported tray, panel, bin, or platform beyond the mounting structure. Side-by-side drawer slides place two rail sections next to each other on the same side of the load, creating a narrow, beam-like structure for applications where width is limited but guided motion, stiffness, and load support are required.

SDS S-Beam Side-by-Side Features
PBC Linear’s SDS S-Beam heavy-duty steel drawer slides use two hardened steel SDP rails arranged side-by-side to create a compact, rigid slide system for narrow industrial designs. By positioning the rails shoulder-to-shoulder, the SDS Series reduces flex and maintains controlled alignment while supporting smooth extension under load. The SDS configuration differs from rear-mount slides (which prioritize maximum outward reach) and face-mount slides (which enclose rails for contamination protection). SDS side-by-side drawer slides are built for fitting heavy-duty extension into slim mounting envelopes while maintaining stable, controlled motion.

Key Functional Characteristics

• Telescoping linear rail assembly using a ball-cage slide mechanism for low-friction guidance
• Side-by-side (same-side) rail arrangement for narrow mounting envelopes and improved stiffness
• S-Beam profile optimized for space-constrained, heavy-duty applications
• Hardened steel SDP rails; commonly zinc-plated finish on industrial variants
• Designed to expose a supported tray, panel, bin or platform fully outward from the mounting structure

Applications
Industrial and commercial applications requiring heavy-duty, full-extension guidance from one side only where width across the assembly is limited but stiffness and controlled motion are critical (examples: narrow machinery trays, cantilevered equipment platforms, industrial bins and drawers).
