The MGW7H is an extended linear guide slider in the HIWIN MG miniature linear guide series, suitable for high-precision linear motion applications. “MGW” indicates a wide-type miniature guide series, “7” indicates the size, and “H” indicates an extended slider.
Advantages of the HIWIN MGW7H extended linear guide slider compared to the standard MGW7C slider:
1. Higher Load Capacity
Due to the increased ball bearing circulation length and contact area, the MGW7H increases dynamic load by approximately 29% and static load by approximately 52%, making it suitable for motion mechanisms with heavy loads.
2. Enhanced Anti-Overturning Capacity
The most significant advantage of the extended slider is its significantly improved torque resistance. For cantilever mounting, off-center mounting, or high-speed motion mechanisms, the stability of the MGW7H is significantly better than that of the MGW7C.
3. Higher Operating Rigidity
Due to the increased number of balls, the MGW7H extended linear guide slider deforms less under load, making it suitable for equipment requiring high repeatability.
HIWIN MGW7H 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
