BulletPoint2 : 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. BulletPoint3 : Top tight type rigid coupling with 2/4 screws to hold the shaft tightly; high torque with rigidity, low inertia and excellent sensitivity. BulletPoint4 : NOTE: The rigid type basically does not allow eccentricity, and it must be fully adjusted during use.
