Telescopic Linear Guide Rail CAD Files

Helix Linear Technologies' Telescoping Linear Guide Rails provide smooth, controlled linear motion with extended travel capabilities in compact spaces. Designed for applications requiring reliable support, high rigidity, and efficient movement, these precision-engineered rails allow components to extend and retract while maintaining stability under load.



Manufactured from precision cold-drawn steel, the rails feature induction-hardened ball raceways and a four-point bearing contact design for durability, load support, and smooth operation. Available in partial extension (HTPE) and full extension (HTDB) configurations, Helix Telescoping Rails offer flexible solutions for different travel and space requirements.





How Telescoping Rails Work



Telescoping rails use nested sliding sections and ball-bearing guidance to provide extended linear travel without requiring a long, fixed guide assembly. As the rail extends, the bearing system supports the moving sections, helping maintain alignment and consistent motion.



Partial extension rails provide controlled travel for applications requiring limited access or movement, while full extension designs allow greater reach for equipment that needs extended positioning or accessibility.





Applications and Industries



Helix Telescoping Rails are designed for a wide range of industrial applications, including:



• Industrial Automation: Extendable machine components, automated positioning systems, and equipment access mechanisms.
• CNC Machinery & Manufacturing: Sliding machine doors, protective enclosures, and maintenance access panels.
• Aerospace & Defense: Aircraft seating mechanisms, equipment positioning, and compact extendable assemblies.
• Material Handling & Logistics: Conveyor systems, sliding platforms, and automated storage equipment.
• Heavy Manufacturing: Industrial machinery, extendable support structures, and equipment requiring rigid linear guidance.
• Mobile Equipment: Sliding equipment compartments, extendable work surfaces, and space-saving mechanical assemblies.





Engineered for Performance in Compact Spaces



Whether designing new equipment or improving an existing system, Helix Telescoping Linear Guide Rails offer engineers a practical solution for achieving extended travel, smooth movement, and dependable support. With multiple sizes and extension configurations available, these rails help optimize machine functionality while minimizing installation space.
