Introduction
Gantry belt-driven linear modules are widely used in automation, CNC machines, and pick-and-place systems due to their high speed and long travel ranges. However, selecting the right module requires careful consideration of technical parameters. In this guide, RYK Motion breaks down the critical factors to help you make an informed decision.
Key Factors for Gantry Belt-Driven Linear Module Selection
1. Load Capacity
-
Calculate the total weight (payload + mounting fixtures).
-
Belt-driven modules (like our RYK Belt-Driven Series) typically handle 5–20 kg, but heavy-duty options are available.
-
Pro Tip: Overestimate by 20% for safety.
2. Precision Requirements
-
Repeatability: Belt-driven modules offer ±0.05–0.1 mm (compared to ±0.01 mm for ball screws).
-
Use ground rails (e.g., HIWIN Linear Guides) for higher accuracy.
3. Speed and Acceleration
-
Belt modules excel in high-speed applications (1–3 m/s).
-
Match the motor’s RPM with the pulley diameter.
4. Travel Length
-
Belt systems support longer strokes (up to 10+ meters) without sagging.
-
For ultra-long spans, consider dual-motor drives (learn more in our Gantry System Guide).
5. Environmental Conditions
-
Dusty/Wet Areas: Opt for IP-rated modules (e.g., IP54).
-
High Temperatures: Stainless steel or special coatings.
6. Motor Compatibility
-
Stepper motors (cost-effective) vs. servo motors (high precision).
-
Check our Motor Integration Guide for pairing advice.
Why Choose Belt-Driven Over Ball Screw or Linear Motor?
-
Cost-Effective: Lower price than linear motors.
-
Maintenance: Belts require less upkeep than ball screws (NSK Bearing Study).
-
No Backlash: Pre-tensioned belts minimize play.
Top Applications of Gantry Belt Modules
-
3D Printing & CNC Routers – High-speed positioning.
-
Packaging Lines – Long-distance transport.
-
Automated Assembly – Repeatable movements.
