Coupling/DURI

Various ways to connect the axis are available! Lightweight and high-rigidity aluminum alloy coupling.

Our "couplings" are used to connect the drive shaft and the driven shaft to transmit power. They are made of a lightweight and highly rigid aluminum alloy (Duralumin) that excels in corrosion resistance, allowing for the construction of a rotation system with low inertia. We offer a set screw type and two types of clamp types, so you can choose the appropriate type. Additionally, different types and shaft diameters can be combined depending on the type and input/output shafts. 【Features】 ■ Connects the drive shaft and the driven shaft to transmit power ■ Excellent corrosion resistance ■ Made of lightweight and highly rigid aluminum alloy ■ Constructs a rotation system with low inertia ■ Available in set screw type and two types of clamp types *For more details, please refer to the PDF document or feel free to contact us.

Flexible coupling "DRFC"/DURI

It is a one-piece flexible coupling that allows for large angular misalignment, eccentricity, and end play.

This is a coupling that utilizes resin. By taking advantage of the properties of resin, it allows for significant deformation, accommodating large eccentricity, angular misalignment, and axial movement. It is ideal for relatively light torque transmission in general industrial machinery. 【Features】 ■ Integrated flexible coupling ■ Allows for large eccentricity, angular misalignment, and end play ■ Absorbs shock and vibration ■ Low inertia moment *For more details, please refer to the comprehensive catalog or feel free to contact us.

High-rigidity coupling for working machinery 'DRDA'

High rigidity coupling for machine tools with low inertia moment and zero backflash.

This is a high-rigidity flexible coupling for disk-type machine tools. With a high-hardness aluminum alloy and a hub outer diameter that corresponds to the shaft diameter, it is the most suitable coupling for high-speed operation. It is ideal for the main spindle and moving axes of machine tools. The installation uses a dedicated jig to align the center, ensuring high coaxiality. There are three types available based on the combinations of the coupling inner diameters, allowing you to choose the most suitable type. *For more details, please refer to the comprehensive catalog or feel free to contact us.*
