PMI’s advanced linear motion components help manufacturers improve their performance by delivering high precision and strong load capacity.

Roller guideways

PMI roller guideways comprise a rail with built-in rollers and a carriage that glides smoothly along the rail with minimal friction. The rollers are designed to distribute the load evenly, ensuring stable and precise motion even under heavy loads. They have high loadcarrying capacity. The design of the rollers and the raceways allows for the distribution of loads over a larger contact area, making them suitable for applications that require the movement of heavy loads with high precision.

PMI roller guideways are also known for their rigidity and stability. The design of the rollers and the rail structure provides increased stiffness, reducing vibration and ensuring consistent positioning accuracy in high-speed or high-load applications.

PMI roller guideways are a popular choice in machine tools, automation, semiconductor manufacturing, and more, where precise linear motion control is essential. Their robust construction, high load capacity, rigidity, and smooth operation make them a reliable solution for demanding applications that require efficient and accurate linear motion control. PMI ground ballscrews are precision mechanical devices used in machinery and automation systems.

Ground ballscrew

Ground ballscrew convert rotary motion into linear motion with high efficiency and accuracy. Ballscrews are designed with precision-ground threads to ensure smooth operation, low friction, and excellent positioning accuracy.

A key feature of PMI ground ball screws is their exceptional precision. The threads on the ballscrew shaft are meticulously ground to tight tolerances, ensuring smooth motion and consistent positioning accuracy. This high level of precision is essential for applications requiring fine control and repeatability, such as CNC machines, industrial robots, and semiconductor manufacturing equipment.

PMI ground ballscrews also offer high efficiency due to their low-friction design. The use of precision-ground ball bearings between the screw shaft and the nut reduces friction, resulting in smoother operation and energy savings. This efficiency is essential for applications that demand high-speed and high-precision linear motion.
