Product Features

✔ Smooth and low-friction linear motion
✔ Excellent load-bearing capability
✔ Easy installation with pre-drilled mounting holes in End Shaft supports
✔ Corrosion-resistant hard chrome plated shaft (ends need to be painted)
✔ Replaceable SC20UU bearing blocks

Applications

• CNC Routers
• Large Format 3D Printers
• Laser Cutting Machines
• Pick & Place Systems
• Automation & Robotics
• Woodworking Machinery
• DIY Motion Systems

Installation Notes

• Ensure rails are mounted on a flat, rigid surface.
• Align both shafts parallel for smooth carriage movement.
• Lubricate bearing blocks before first use for optimal life.
• Recommended to use a dial gauge for precision alignment in CNC applications.

Recommended Usage:

• Horizontal light-duty motion systems
• Low cutting force CNC
• 3D printer gantry (lightweight extruder setups)
• Automation sliders

Not Recommended For:

• Heavy vertical loads
• High cutting force CNC routing
• Precision applications requiring minimal flex

Approximate Load Guidance (Per Block)

• Dynamic Load Rating: ~980 – 1100 N
• Static Load Rating: ~1500 N
• Practical Safe Working Load (per shaft setup):
  300–600 N depending on span and load position
• Load capacity significantly reduces when load is applied at the center of the 1200mm span
