Roller linear guide Rail Plus

28 mm43 mmsteel

Product Overview
Steel Rail Plus linear guide systems from PBC Linear are designed to address misalignment in parallel-rail assemblies. The system combines cold-drawn, zinc-plated steel rails (available in multiple widths and lengths up to 5,000 mm) with lightweight aluminum carriages that use concentric and eccentric cam rollers. Adjustable roller preload enables heavy-duty operation, smooth motion and flexible mounting options.

Key Functional Elements

• Rails: cold-drawn, zinc-plated steel in compact U-shaped profiles for space-efficient automation and robotics installations; lengths up to 5,000 mm and example widths of 28 mm and 43 mm available.
• Carriages: aluminum bodies equipped with 3–6 cam rollers (concentric and eccentric) and adjustable preload to tune rigidity and running behavior.
• Carriage variants: guiding, floating and rotating types to match alignment and constraint requirements.

Carriage Type Functions

• Guiding carriage — defines the motion path and supports the primary load; roller contacts provide two-point constraint in axial and radial directions.
• Floating carriage — allows slight lateral movement to compensate for rail spacing errors while constraining radial motion.
• Rotating carriage — permits limited angular adjustment to accommodate non-parallel or non-coplanar rails.

Lubrication & Contamination Protection
Carriages feature adjustable preload plus integrated oil‑soaked felt wipers and a scraper blade for continuous self-lubrication and debris protection, reducing maintenance needs.

Performance Highlights

• Maximum dynamic capacity (collection reference): 20,520 N.
• Smooth motion and heavy-duty capability via cam-roller arrangements and adjustable preload.
• Mounting flexibility with counterbore options on rails and carriage compatibility with SRP-series components.

Applications
Intended for parallel-rail linear motion systems that require automatic alignment or compensation for rail spacing/parallelism errors — typical uses include automation, robotics, material handling and heavy-duty positioning systems.

Ways to Order (collection-level)

• Configuration tools are available to size and specify Steel Rail Plus components.
• Quotation and ordering options are provided through the site tools (configure / get-a-quote pathways).
