Torsional couplings for mobile hydraulic applications

Torsional couplings from jbj Techniques offer many advantages including low weight with high torsional stiffness and a lengthy service life. These durable products are maintenance-free and also include a range for SAE flywheels too.  jbj Techniques torsional couplings ensure that torque transmission does not exert harmful reaction loads on equipment, and they feature a combination of materials that allow designers and users to cater for variations in both torsional stiffness and environmental resistance. The couplings are available with oil, heat and corrosion resistant elements (Hytrel®, Zytel®) and – critically for some users – may be specified in both single and multiple units. 

The jbj Techniques range of torsional couplings solve torsional vibration problems which are typical of those found in diesel engine applications: here, the torsional coupling dampens torsional vibrations and tunes the system to have critical speeds which are outside the operating range. Whatever the application, jbj Techniques says that it can analyse it and determine the exact torsional coupling needed for almost any project.

The company offers useful engineering back up and assistance for machine builders seeking the correct model and size of coupling for almost every application.
