Partial-extension linear slide SDP series

drawerheavy-dutycorrosion-resistant

Overview
Partial-extension heavy-duty drawer slides (SDP Series) are telescoping steel rail assemblies with an internal slider, precision ball cage, and hardened external rails. The partial-extension design allows the load-bearing platform to extend only part of the rail length while maintaining support inside the cabinet or frame for compactness and stability. PBC Linear’s SDP Series serves as a standalone partial-extension slide and as a modular element for rear-mount, face-mount, and side-by-side configurations.

Key advantages

• Partial-extension motion for guided travel where full extension is unnecessary
• Compact footprint for simplified integration into machine frames and equipment
• Hardened steel construction with corrosion-resistant finish
• Precision ball guidance for smooth, repeatable performance under load

Applications

• Machine trays, tool compartments and equipment drawers
• Service panels and machine access doors
• Automation systems, industrial storage and racking
• Lightweight mobile equipment and rack-mounted enclosures requiring limited travel
