HIWIN MGW14H MGW linear guide is available in three precision grades: Standard (C), High Precision (H), and Precision (P). The appropriate precision grade can be selected based on the positioning accuracy, parallelism, and assembly requirements of the equipment to meet the needs of different application scenarios.
MGW linear guide is divided into three standard precision grades: C, H, and P. The higher the grade, the smaller the dimensional tolerances and the better the parallelism.
C Grade (Standard): Suitable for general automation equipment, 3C auxiliary equipment, conveying mechanisms, office equipment, and other applications where high precision is not required.
H Grade (High Precision): Suitable for medical equipment, optical devices, conventional precision testing instruments, and small automation modules; this is the mainstream grade used in the industry.
P Grade (Precision): Suitable for semiconductor equipment, precision measuring instruments, high-precision positioning mechanisms, and miniature precision machine tools.
