Description:

[DIMENSION] - Outer Diameter: 8mm/0.31"; Length: 18mm/0.71"; Bore Diameter: 2.3x2.3mm/0.09"x0.09"; Thread Diameter: M3. [MATERIAL] - Universal joint shaft coupling is made of iron, and then electroplated, much stronger, wearproof, durable to use. [FEATURE] - Provides torque transmision and alignment, cost effective coupling design, which is very flexible and easy for use. [FUNCTION] - Shock mitigation, noise reduction; when the rated torque is exceeded, the coupling can protect the safety of the linkage. [APPLICATION] - The universal joint coupling is compatible with straight shaft motors, and it is used for model cars, model ships, robots and other types of metal transfer.
