FAQ – Belt Module GT45 Linear Belt Module
Q: Can the travel length of the GT45 module be customized?
A: Yes, the travel range can be customized from 10mm up to 3000mm to meet different application needs.
Q: What types of motors can be installed?
A: The GT45 module supports 57/86 stepper motors and 40/60 servo motors. The motor flange can also be tailored upon request.
Q: What is the load capacity of this belt driven linear module?
A: The reference load is 20kg horizontally and 20kg vertically. For higher load requirements, please contact us for technical support.
Q: What is the positioning accuracy of the GT45 synchronous belt module?
A: It uses a 3M synchronous belt with 75mm lead and achieves up to ±0.1mm accuracy, ensuring precise motion control even at high speed.
Q: What applications is this belt module suitable for?
A: The GT45 is widely used in automation production lines, CNC equipment, laser systems, pick-and-place machines, and precision positioning systems.
Q: Can I order with customized nut configurations or worktable design?
A: Yes. The number and size of nuts as well as the worktable thickness can be customized based on project requirements.
Q: What is the difference between a belt module and a ball screw linear module?
A: Belt modules use a synchronous belt for transmission, offering higher speed and lower noise, making them ideal for lightweight, high-speed applications. Ball screw modules offer higher precision and load capacity for heavier-duty tasks. See our Ball Screw Linear Module for comparison.
Q: Do you provide OEM belt module manufacturing services?
A: Yes, as a factory-direct linear belt module manufacturer, we support OEM/ODM orders including custom travel length, motor flange, worktable, and nut configuration, along with free 3D drawings and technical support.
