Linear Motion Parts

A linear shaft is a crucial mechanical component used in various motion systems to provide precise linear movement. Typically made from high-strength materials such as stainless steel or carbon steel, linear shafts serve as guides or supports for linear bearings, enabling smooth and accurate motion in automation, CNC machinery, robotics, and other industrial applications. They are often precision-ground and coated to enhance durability, corrosion resistance, and wear resistance. Available in different diameters and lengths, linear shafts can be customized to meet specific engineering requirements, ensuring optimal performance in high-precision environments.

Shaft Supports are structural components designed specifically to rigidly secure and mount linear shafts to a machine frame or base. They provide fixed points for the guide shafts in a linear motion system. They come in various configurations (e.g., end-mount, flange-mount) and are typically used in automation, CNC machinery, and robotics alongside linear bearings and ball screws.

A linear guide is a precision mechanical system designed to facilitate smooth and accurate linear motion along a fixed path. It typically consists of a linear guide rail, linear guide bearings, and a linear guide slider. The rail serves as the guiding track, while the bearings minimize friction, allowing the slider to move effortlessly along the rail. This system is widely used in applications requiring high precision and stability, such as CNC machines, 3D printers, and industrial automation. Its robust design ensures durability, smooth motion, and reliable performance in demanding environments.

Cross roller guides and tables are precision linear motion components designed for high rigidity and high positioning accuracy, with strong resistance to multi-directional moment loads.They use cylindrical rollers arranged in a crossed configuration between precision-ground raceways, enabling low-friction motion and stable load distribution. Available in both guide and table configurations with multiple mounting hole options, they are suitable for precision automation systems, optical equipment, semiconductor machinery, and inspection equipment, often used together with ball screws and linear guide systems.

A ball screw is a highly efficient transmission device that converts rotary motion into linear motion. It consists of a screw shaft, a nut, and circulating ball bearings. The key feature lies in the rolling contact between the screw and the nut via the balls, which significantly reduces friction compared to traditional sliding screws. Ball screws offer high transmission efficiency, excellent positioning accuracy, minimal backlash, and long service life. They are widely used in CNC machines, automation equipment, and precision instruments. With customizable options for load capacity, travel length, and accuracy grade, ball screws are an ideal choice for achieving high-speed, high-precision linear motion control.

Known for their accuracy and stability, Ball Screw Support Assemblies are essential components in mechanical transmission systems.

A lead screw is an efficient transmission component that converts rotational force into precise linear motion via helical movement. Available with a standard 30° thread angle and in both left-hand and right-hand threads, these components offer flexibility for various applications. They are made from durable materials like SUS304 and S45C. With shaft diameters ranging from 4 mm to 68 mm (approximately 0.16 inches to 2.7 inches), a complete lead screw assembly typically consists of the screw body and its matching lead screw nut, which moves along the screw as it rotates. To ensure smooth and accurate operation, the ends of the screw need to be installed with a stable end support. In applications that require precise position monitoring, a position indicator can be integrated and secured by its support to display the nut's current position in real-time. Together, these products form a complete and reliable linear motion solution, widely used in various industrial machinery, automation equipment, and precise positioning systems.

Ball spline is a mechanical transmission component that combines linear motion and torque transmission functions. It consists mainly of a splined shaft and a spline nut with circulating ball elements. Its key feature is the ability to transmit torque efficiently even during axial movement, thanks to the rolling motion of the balls between the grooves, which greatly reduces friction and wear. This enables high precision, high rigidity, and long service life. Compared to traditional sliding splines, ball splines offer smoother operation and are ideal for applications that require both rotation and linear movement, such as automation equipment, robotic joints, machine tool slide units, and packaging machinery. They also effectively absorb eccentric loads and impact forces, making them an ideal solution for high-speed and high-load conditions.
