Tear resistant
Ageing resistant

So polyurethane jaw coupling inserts from Yantai Zhengyuan Polyurethane Co.,Ltd.come in a variety of designs to be suitable for different type of jaw couplings.
A jaw coupling is a power transmission coupling that can also be used in motion control applications, for example, a motor. It connects two shafts while minimizing vibrations and compensating for any parallel, angular, and axial misalignment.
Jaw couplings are made up of three parts: two metal hubs sandwiched around a polyurethane insert commonly called a “spider.” The three parts press-fit together, and a metal jaw from each hub meshes with the lobes of the spider. Torque is transmitted through the PU spider in compression.
Polyurethane jaw coupling inserts from Yantai Zhengyuan Polyurethane Co.,Ltd. are designed to be fail-safe, which means that if the PU insert wears out, the hubs’ teeth will mate and the coupling will continue to transmit torque without damaging the equipment.
