Flexible Couplings 5mm Shaft to 8mm screw D:19mm H:25mm
This 5mm to 8mm flexible shaft coupling (19×25mm) connects stepper motors to lead screws or shafts. It reduces vibration and compensates for misalignments, ensuring smooth torque transmission in 3D printers, CNC machines, and robotic systems.
هذه الوصلة المرنة للعمود (بقطر 5 مم إلى 8 مم، وأبعاد 19×25 مم) تربط محركات السائر بمسامير التوجيه أو الأعمدة. وهي تقلل الاهتزاز وتعوّض عدم المحاذاة، مما يضمن نقل عزم الدوران بسلاسة في الطابعات ثلاثية الأبعاد، وآلات التحكم الرقمي بالكمبيوتر (CNC)، وأنظمة الروبوتات.
The 5mm to 8mm Flexible Shaft Coupling is a precision-machined aluminum coupler designed to connect a 5mm stepper motor shaft to an 8mm lead screw or drive shaft. With a diameter of 19mm and height of 25mm, it’s perfect for compact yet demanding motion control applications.
Its helical (spiral cut) design provides flexibility that accommodates axial, radial, and angular misalignments, while absorbing vibration and minimizing stress on connected components. This makes it ideal for systems requiring accurate, smooth torque transfer—like 3D printers, CNC machines, laser engravers, and robotics.
