Heavy Duty Drawer Slides - SDP Partial Extension

Heavy-duty partial extension drawer slides are telescoping linear rail assemblies built around an internal slider, precision ball cage, and external hardened steel rail, allowing the load-bearing platform to extend only part of the rail length while part of the platform remains supported inside the structure for added stability and compactness. PBC Linear’s heavy-duty steel SDP Series provides the foundational drawer slide rail used as a standalone partial-extension slide and as the building block for SDB rear mount, SDF face mount, and SDS side-by-side drawer slide configurations. By pairing, opposing, or placing SDP rails side-by-side, PBC Linear can create drawer slide systems optimized for extended reach, added contamination protection, or narrow-width mounting. As a standalone, compact, high-capacity drawer runner solution, SDP slides are used where full extension is not required but controlled guided motion and load support are still critical. Their hardened steel construction, corrosion-resistant finish, and precision ball guidance make them well suited for machinery trays, service panels, equipment compartments, automation systems, industrial storage, machine access doors, and lightweight mobile equipment. By limiting travel, the SDP design simplifies integration, reduces overall system size, and maintains consistent performance under load.
