The MGW9C miniature linear guide features a widened guide rail design, enhancing torque load capacity and allowing for single-axis operation. The slider adopts a four-way equal load design, which can simultaneously withstand loads in the up-down, left-right, and front-back directions, and operates smoothly with low frictional resistance and high positioning accuracy.
HIWIN MGW9C Miniature Linear Guide Core Parameters and Structure
Specifications: Slider width 30mm, rail width 18mm, combined height 12mm.
Contact Design: Utilizes a Gothic four-point contact design, capable of withstanding loads in all directions.
Load Capacity: The wide design significantly improves torque resistance, allowing for single-axis operation.
Ball Retainer: Equipped with a ball retainer to prevent ball spillage when the slider disengages from the rail.
HIWIN MGW9C ball linear guide, due to their small size, high precision, and good rigidity, are mainly used in the following industries:
1. Semiconductor and electronics manufacturing
2. Optical and laser equipment
3. Medical devices
4. Automation and robotics
5. Electronic instruments
6. Measuring and testing instruments
