German poly-norm coupling poly-norm model poly-norm price

poly-norm coupling sliders are ring-shaped, made of steel or wear-resistant alloys. Cross-slider couplings are suitable for transmissions with lower speeds and higher torque transmission. Slider couplings consist of two shaft hubs and a center slider. The center slider, as a torque-transmitting element, is usually made of engineering plastics; in special cases, other materials such as metals may be selected. poly-norm coupling structure: There are two main structural forms of couplings: (1) alignment of the two shafts is achieved by bolts in reamed holes, and torque is transmitted by the bolt shank withstand compression and shear.
