BRIEF INTRODUCTION: We are a professional manufacturer of linear guides, linear modules, and ball screws. Our facilities cover 33,333 square meters with a building area of 16,000 square meters. With over 10 years of effort, we have become a strong brand providing international standard products for customers worldwide.




The accuracy of CH series linear guides is divided into five levels: Common (C), High (H), Precision (P), Super-Precision (SP), and Ultra-Precision (UP).

Proper lubrication reduces friction, prevents burns, and extends rolling fatigue life. We support both Grease Lubrication (Lithium soap-based) and Oil Lubrication (32-150 cSt consistency).

Installation must be configured based on machine vibration, impact force, and required accuracy. Always distinguish between the Reference Rail (marked MA) and the Driven Rail.
