• Crafted from high-quality aluminum alloy, these rigid couplings offer exceptional durability and corrosion resistance, ensuring long-lasting performance in a variety of applications
• Aluminum alloy material with anodized surface for excellent corrosion resistance. Blue color, suitable for working in high temperature (-80 degree C / +300 degree C) and harsh environment
• Rigid couplings are securely connecting drive and driven shafts to rotate together and transmit motion and torque. Ideal for short support shafts, bushing models, miniature shafts, airplane / ship / car models
• Widely used in blowers,3D printer,DIY robots,CNC machine,stepper motors,etc. Similar to rigid clamp couplings, shaft couplers are used to hold bearings and sprockets tightly on the shaft, and are used in motor and gearbox assemblies
• Suitable for connecting two axis with different diameters, can also be connected with a motor axis, or connecting shafts of different diameters
