The shaft couplings are mechanical component that connect the drive shaft and driven shaft of a motor, etc., in order to transmit power..
Shaft couplings introduce mechanical flexibility, providing tolerance for shaft misalignment. As a result, this coupling flexibility can reduce uneven wear on the bearing, equipment vibration, and other mechanical troubles due to misalignment..
The size is complete and the surface is smooth, convenient for use. The flexible connection design can absorb vibration and compensate for radial, angular and axial misalignment..
This shaft coupling features simple structure and compact size, it is convenient for installation..
It is commonly used to connect 3D printer, actuating motors, stepping motors, encoders, machine tool, etc..
