Zero backlash coupling in the use process, the elastic body is compressed while ensuring coupling fairly torque, axial, radial, can absorb the angle deviation and other types of vibration.
powerchem,.,.,
Powerchem plum shaped elastic body has great flexibility, which can be compressed to a great extent. The elastic body material is relatively soft, squeeze it impact on the sleeve is very low. Therefore, tooth sleeve shaped load can withstand multiple recurrent and not easy to be damaged so as to ensure long service life
