Roller linear guide Rail Standard

35 mm28 mm43 mm

Overview
Steel Rail Standard linear guides combine U-shaped ground steel linear rails with high-strength aluminum carriages fitted with 3–5 steel cam rollers (concentric and eccentric). The rail defines the fixed track; the carriage (slider) supports and guides the moving load. Concentric rollers bear the load; eccentric rollers enable adjustment to remove play, ensuring smooth, controlled motion.

Design features

• High-strength aluminum carriage bodies for lightweight, rigid support
• 3–5 steel cam rollers per carriage (concentric and eccentric types for load-bearing and play adjustment)
• U-shaped ground steel linear rails for precise guidance and repeatability

Lubrication & contamination protection

• Integrated oil-soaked felt wipers supply continuous lubrication to raceways
• Scraper blade removes debris and contaminants to protect rolling surfaces in harsh environments

Mounting & customization

• Rails available with counterbore mounting (flat-bottom holes for thin-head screws that sit flush or below the surface)
• Option for countersunk mounting (angled holes for tapered screws that sit fully flush) via configuration

Performance & applications

• Adjustable preload to increase rigidity and stability
• Maximum dynamic capacity: 19,650 N
• Low friction combined with high rigidity — suitable for compact, high-speed automation, material handling and robotics
• Rail lengths available up to 3,200 mm
