In advanced machinery and automation, achieving precise and reliable linear motion is essential. Round linear guide shafts form a core component in this pursuit, serving as the backbone of high-accuracy linear systems. iHF Group has developed a robust series of Standard Straight Shaft Linear Guides designed to meet the stringent demands of industrial, medical, and precision engineering applications.

Linear motion systems rely on the combination of guide shafts and linear bearings to translate rotational or motorized input into smooth linear movement. Any imperfections in shaft geometry or surface finish can amplify friction, induce wear, and compromise system accuracy.
The iHF Group Round Linear Guide Shafts are manufactured to G6 high-precision tolerance, ensuring minimal clearance and a flawless pairing with linear bearings. This tolerance ensures smooth, vibration-free motion, even under high load or high-speed conditions.
● Smooth Operation: Reduced vibration and friction for accurate motion.
● Long Service Life: Hard Chrome Plating achieves a surface hardness of HRC 58, providing exceptional wear and corrosion resistance.
● Design Flexibility: Shafts available in diameters from 3mm to 50mm and lengths from 10mm to 1500mm.
The shaft’s surface undergoes high-quality Hard Chrome Plating, providing not only enhanced hardness but also superior resistance to oxidation, chemicals, and environmental wear.
Each shaft is meticulously ground to maintain straightness and roundness within strict tolerances, critical for micro-precision equipment such as medical devices, lab automation, and semiconductor manufacturing tools.
A solid steel core ensures the shaft withstands bending and deflection, making it suitable for heavy-duty industrial applications.


iHF Group provides extensive customization options to meet various engineering needs:
● Diameter Flexibility: From 3mm for micro equipment to 50mm for large industrial setups.
● Length Options: Tailored lengths from 10mm to 1500mm.
● Surface Treatments: Optional additional coatings for extreme corrosion environments.
● Industrial automation machinery
● CNC machine tools
● Laboratory automation instruments
● Medical imaging and robotic devices
● Packaging and material handling equipment
