Partial Extension Steel Drawer Slide

Industrial Drawer Slides - SDP Partial Extension

Industrial partial extension drawer slides are telescoping linear rail assemblies that allow a heavy duty load-bearing carriage to extend only part of the rail length while remaining partly supported inside the structure. This partial-extension design provides compact guided motion, high load support, and greater stability than designs that require the carriage to travel completely beyond the supporting rail. The assembly uses an internal slider, precision ball cage, and hardened steel outer rail to guide the moving load smoothly through the available stroke.

PBC Linear SDP Series heavy-duty steel drawer slides are designed for industrial applications where full extension is unnecessary but controlled linear travel and load capacity are important. The SDP rail can be used by itself as a compact partial-extension drawer slide or as the core rail used to build SDB rear-mount, SDF face-mount, and SDS side-by-side drawer slide systems. Pairing, opposing, or arranging SDP rails side by side allows related configurations to provide longer extension, greater contamination protection, or narrower mounting geometry.

SDP partial extension drawer slides are used for machinery trays, service panels, equipment compartments, automation systems, industrial storage, machine access doors, and mobile equipment. Hardened steel construction, corrosion-resistant surfaces, and precision ball guidance provide rigid, repeatable movement under load. Because part of the moving carriage remains supported inside the rail during extension, the system can reduce overall installation space while maintaining stable guided motion.

Industrial partial extension drawer slides are telescoping linear rail assemblies that allow a heavy duty load-bearing carriage to extend only part of the rail length while remaining partly supported inside the structure. This partial-extension design provides compact guided motion, high load support, and greater stability than designs that require the carriage to travel completely beyond the supporting rail. The assembly uses an internal slider, precision ball cage, and hardened steel outer rail to guide the moving load smoothly through the available stroke.

PBC Linear SDP Series heavy-duty steel drawer slides are designed for industrial applications where full extension is unnecessary but controlled linear travel and load capacity are important. The SDP rail can be used by itself as a compact partial-extension drawer slide or as the core rail used to build SDB rear-mount, SDF face-mount, and SDS side-by-side drawer slide systems. Pairing, opposing, or arranging SDP rails side by side allows related configurations to provide longer extension, greater contamination protection, or narrower mounting geometry.

SDP partial extension drawer slides are used for machinery trays, service panels, equipment compartments, automation systems, industrial storage, machine access doors, and mobile equipment. Hardened steel construction, corrosion-resistant surfaces, and precision ball guidance provide rigid, repeatable movement under load. Because part of the moving carriage remains supported inside the rail during extension, the system can reduce overall installation space while maintaining stable guided motion.

Frequently Asked Questions

What are partial extension drawer slides?
Partial extension drawer slides are telescoping linear rail assemblies that allow a carriage or load to travel only part of the rail length. Part of the moving section remains supported inside the rail during extension.
How far do partial extension drawer slides travel?
Partial extension slides typically travel less than the full rail length. In the PBC Linear SDP Series, stroke can reach approximately half the rail length, with maximum stroke up to 1,013mm depending on rail size.
What is the difference between partial extension and full extension drawer slides?
Partial extension slides keep part of the moving carriage inside the supporting rail, while full extension slides allow the moving section to travel farther outward. Partial extension can provide a more compact and highly supported arrangement when full access is not required.
Why use heavy-duty partial extension drawer slides?
Heavy-duty partial extension drawer slides are used when high load support, guided motion, and compact installation are more important than full extension. They are commonly used in machinery trays, service panels, equipment compartments, and industrial access systems.
How much load can heavy-duty partial extension drawer slides support?
Load capacity depends on rail size and configuration. PBC Linear SDP partial extension drawer slides support loads up to 24,230N.
What parts make up a partial extension drawer slide?
A typical partial extension drawer slide includes an outer rail, an internal slider or carriage, and a precision ball cage that guides the moving components along the rail.
What is the advantage of keeping part of the carriage inside the rail?
Keeping part of the carriage inside the rail maintains support during extension, which can improve stability and reduce the amount of structure required outside the mounting area.
Are partial extension drawer slides only used for drawers?
No. Industrial partial extension slides are also used for machinery trays, service panels, access doors, equipment compartments, automation systems, and other moving assemblies that require guided linear travel.
What rail lengths are available for SDP partial extension drawer slides?
PBC Linear SDP rail lengths range from 130mm to 1,970mm, depending on the selected size and configuration.
Can partial extension drawer slides be used to build other slide configurations?
Yes. PBC Linear SDP rails are also used as the base rail for SDB rear-mount, SDF face-mount, and SDS side-by-side drawer slide configurations.
