Abssac is now able to supply a range of gear couplings formerly marketed under the names, Deck and Sier Bath. One of the main advantages of gear couplings is their excellent torsional rigidity and ability to transmit high torque via a relatively small package. Gear couplings are usually all metal in construction and require lubrication for optimum performance. The Abssac units can also interchange directly with competitive products, and a replacement guide is available to help engineers with part interchanges.
