NBK’s Jaw type couplings range in outside diameters from 14-95 mm. We have the capability to have bore diameters in both metric and imperial sizes. Our jaw couplings work well with servomotors, stepping motors and general-purpose motors.

They are strong at high torque levels, absorb vibration and provide good electrical insulation. The jaw coupling can be used with one of four colored elastomer sleeves of varying hardnesses according to the JIS (Japanese Industrial Standard) scale. They also provide a tight or easy fit both with their own benefits. The easy fit allows easy assembly and partition, thus reducing the required assembling and maintenance time. Even when the coupling is less visible it is easy to mount a hub on the shaft. For the tight fit sleeves, they can be used under zero backlash within the correct torque values. The elastomeric sleeve enables a gain in vibration absorption in servomotors thus allowing them to achieve high responsive operation exceeding disk-type couplings. The jaw type couplings can work within the temperature range of -20 to 60 degrees Celsius (-4 to 140 degrees Fahrenheit).
