Telescoping Steel Drawer Slides: Heavy-Duty Linear Motion Reach

Drawer slides made of steel with nested telescopic sections
are engineered by PBC Linear to handle heavy loads, long strokes, and
dependable operation, delivering a durable linear motion solution for
industrial and mechanical applications. Whether you need partial extension,
full over-travel, compact side-by-side mounting, or extreme load capacity,
there is a configuration to match your application requirements.


What Are Telescoping Drawer Slides?

drawer slide line up

Telescoping drawer slides are extendable slide-and-rail assemblies that allow a load to travel beyond the installed length of the rail through nested, ball-bearing-guided members. The PBC Linear Steel Drawer Slide family includes four telescoping slide designs and one heavy-duty linear rail configuration, each offering different extension styles and mounting formats while sharing hardened steel construction and precision ball guidance. Precision steel balls deliver smooth, guided motion under load, while hardened raceways improve wear resistance and help reduce operating noise. Unlike lightweight cabinet-style slides, these are industrial-grade linear slide rails built for strength, durability, and long service life.

Drawer Slide Features:

  • Cold drawn steel rails induction hardened to 56.5–60.5 HRC
  • Zinc-plated surfaces for corrosion protection
  • High-quality steel ball bearings for reduced wear and smooth motion
  • Pre-lubricated rails for reliable operation from day one

 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
