Motion Control Couplings

Couplings / joints are components used to transmit power between shafts. Used in combination with power sources such as engines and motors, it is used in many general machines. The material is mainly various alloys. In addition to simply transmitting power, there are flange-type couplings that do not transmit vibration and vibration of one shaft to the other, and metal spring couplings with excellent flexibility. Select the most suitable parts according to the relationship between the two shafts to be connected and the expected eccentricity and declination.
