This is a coupling that transfers power by buffer between hub teeth of jaw coupling and urethane element.

 Features

→ Power transfer by polyurethane element shows high torsional rigidity, impact relief, and vibration absorption. 
→ It exhibits excellent wear resistance, ozone resistance, oil resistance and chemical resistance. 
→ It has simple structure the small size compared to motor capacity. 
→ It does not require lubricant. 
→ With strong and excellent flexibility and resistant elasticity as greatest advantages of urethane elasteomer, urethane spider can withstand compressoin load until torsional angle reaches 5 degrees.
