Steel Rail Standard & Steel Rail Plus Linear Guides
Steel Rail Standard: Heavy-Duty Linear Motion
Designed for high loads and harsh environments, the Steel Rail Series delivers smooth, precise motion with unmatched rigidity and wear resistance. Perfect for industrial automation, packaging equipment, and machine tools.
Key Features:
- Variety of Roller Configurations: 3, 4, and 5 roller carriages available in several configurations for optimal load capacities and moment loads.
- High Load Capacity: Maximum dynamic capacity of 19,650 N.
- Low Friction & Noise: Concentric and eccentric rollers provide quiet, fluid motion.
- Wear-Resistant Construction: Cold-drawn, ground steel rails are induction hardened for long life.
- Mounting Flexibility: Counterbore and countersunk rail options.
- Integrated Lubrication: Oil-soaked felt wipers keep the rails clean and lubricated.
- Built-in Scraper Blade: Eliminates debris and contaminants from the rail surface
- Adjustable Preload: Tighten or loosen the preload to balance rigidity and smoothness for your specific application.
Steel Rail Plus: Solution for Parallel Rail Applications
Perfect for applications where parallelism is hard to achieve, Steel Rail Plus compensates for mounting errors to reduce binding, wear, and downtime. Use a combination of guiding + floating carriages or rotating + floating carriages to create successful parallel systems.
Key Features:
-
Three Carriage Types Provide Different Self-Alignment Capabilities:
- Guiding Carriage: Fully constrains motion in all directions for one-sided precision.
- Floating Carriage: Allows axial movement to compensate for parallel rail gaps.
- Rotating Carriage: Supports slight angular misalignment with full radial load support.
- Variety of Roller Configurations: 3, 4, 5, and 6 roller carriages available in several configurations for optimal load capacities and moment loads.
- Assortment of Roller Configurations: Carriages available with 3-6 double bearing rollers in several configurations for optimal load capacities and moment loads.
- High Load Capacity: Maximum dynamic capacity of 20,520 N.
- Self-Aligning Systems: Perfect for applications with uneven surfaces.
- Variety of Features: Equipped with all the same great features of Steel Rail Standard.
