This D20L25 aluminum plum flexible shaft coupling is a precision-engineered mechanical connector designed to link motor shafts and drive components with reliability and efficiency. Constructed from durable aluminum alloy, the coupling features a distinctive three-jaw split design with a flexible red elastomer spider insert that sits between the jaws, providing excellent vibration dampening and shock absorption during operation. The integrated rubber cushion pad also helps reduce operational noise, protecting connected equipment from sudden load changes. Available in a wide range of bore sizes — 5mm, 6mm, 6.35mm, 8mm, and 10mm — this coupling accommodates various shaft diameters, making it highly versatile for stepper motors, servo motors, and general shaft-to-shaft power transmission setups. The outer diameter measures 20mm with a length of 25mm, offering a compact yet robust form factor. The split clamp design allows for straightforward installation and maintenance while tolerating minor angular and parallel misalignment between connected shafts. Ideal for CNC machines, 3D printers, robotics, and other precision motion control applications.
