What Are Telescoping Drawer Slides?
Built for Heavy Loads and Industrial Use
Designed for Real-World Environments
One of the biggest advantages of PBC Linear Steel Drawer Slides is their ability to handle substantial loads while maintaining smooth extension. Load ratings are determined with force applied at the center of the slider while the rail is fully extended representing real-world worst-case conditions.
Depending on the series, PBC Linear Drawer Slides can support loads from a few thousand newtons to over 65,000 N, making them suitable for:
- Industrial storage systems
- Rail Lengths: 130–1,970 mm
- Stroke: 148–2,026 mm
SDP – Steel Drawer Partial Extension Slides
The SDP series uses an internal slider, ball cage, and external rail to provide partial extension travel. Stroke length can reach up to half the rail length, making it a strong solution where full extension isn’t required but strength and guidance are.
• Max Load: 24,230 N
• Rail Lengths: 130–1,970 mm
• Stroke: 74–1,013 mm
SDB– Back-Mounted Telescopic Slides
The SDB series mounts two SDP rails back-to-back, allowing stroke to extend beyond the full length of the slider. This design enables long-travel telescopic motion in a compact envelope. Ideal for applications needing extended reach and full access.
• Max Load: 3,092 N
• Rail Lengths: 130–1,970 mm
• Stroke: 148–2,026 mm
SDF– Face-Mounted Telescopic Slides
The SDF series uses two SDP rails face-to-face and incorporates a dust-resistant design to help protect steel balls from contamination. Perfect for environments where debris protection is important.
• Max Load: 1,909 N
• Rail Lengths: 130–1,970 mm
• Stroke: 148–2,026 mm
SDS – S-Beam Compact Slides
The SDS series mounts two SDP rails side-by-side in a thin S-beam structure, making it ideal for tight spaces where width is limited. A smart choice when space-saving design is critical.
• Max Load: 5,578 N
• Rail Lengths: 290–1,570 mm
• Stroke: 296–1,520 mm
SDC – C-ShapedHeavy-Duty Linear Rail
The SDC series features a C-shaped rail design. The internal slider does not extend past the external rail, and multiple internal sliders can be used on the same rail. This configuration is ideal for extreme load applications and custom motion platforms.
- Max Load: 65,272 N
- Rail Lengths: 130–1,970 mm
- Stroke: 30–1,310 mm
The Smart Choice for Cost-Sensitive Linear Motion
All steel rails are zinc plated to resist rust and corrosion. Combined with hardened steel construction, this provides a long-lasting motion solution for industrial environments where exposure to humidity or mild contaminants may occur.
PBC Linear Drawer Slides are well suited for applications that require:
• Heavy-duty telescopic motion
• Long extension travel
• Rigid steel linear support
• Industrial durability
Whenever a system needs strong, guided linear extension rather than shaft-based linear bearings, PBC Linear Drawer Slides provide a dependable alternative. With high load capacity, hardened steel construction, and corrosion protection, PBC Linear Steel Drawer Slides deliver the strength and versatility engineers need.
Common uses include:
• Machine access doors and service trays
• Battery and electronics racks
• Industrial storage and tool systems
• Automation equipment platforms
• Specialty vehicle compartments
