are general type of couplings that are designed with an elastomeric element that is positioned between the two metal hubs with interlocking teeth. This element is also referred to as a spider. The element is very important because it defines the torque rating of the coupling. Besides, it also determines the coupling's response to chemicals, vibrations, temperatures, high speed, and misalignment.Selecting the right element is as important as selecting the correct coupling. The common materials used to design the element include Nitrite butadiene rubber (NRB). It resembles natural rubber
in elasticity, resistance to oil, and resilience. It offers the best damping capability among all elastomeric elements. Urethane is another common material used to make the element. It has impressive oil and chemical
resistance. Besides, Urethane has 1.5 times the torque capability of Nitrite butadiene rubber. Other materials used to make the element are Hytel and Bronze. Visit our site to see the full list of available elements and pick your preferred choice.
