Since applications in the field of servo technology and robotics requier smaller and smaller components of the drive chain Enemac released the miniature couplings EWJT and EWJTC. They consist of two aluminum hubs and one elastomer star. They differ in their shaft mounting options: The EWJTC is equipped with radial clamping hubs, while the cheaper variant EWJT is equipped with set screws.
The EWJT series is designed for speeds of up to 27,000 rpm. Both types of coupling can be used in a temperature range between 253 K and 343 K. There are 3 sizes available with two different elastomer stars, which cover a torque range between 0.7 Nm and 12.5 Nm. Shafts between 3 mm and 14 mm can be received.
