Common questions
What is an elastomeric coupling?
An elastomeric coupling is a type of flexible shaft coupling that uses an elastomer element to transmit torque while absorbing vibration, shock and minor shaft misalignment. An elastomeric flexible coupling helps protect rotating equipment by reducing wear on connected components and improving overall system reliability in demanding industrial applications.
What are elastomeric couplings used for?
Elastomeric couplings are commonly used to connect rotating equipment such as pumps, motors, conveyers, fans and gearboxes. An elastomeric pump coupling helps dampen vibration and accommodate misalignment between connected shafts, which can extend equipment life and reduce maintenance requirements. These couplings are widely used in industries including general industries, chemical processing, water treatment, and pulp and paper industry.
What are the different elastomeric coupling types?
There are several elastomeric coupling types with the most common being jaw (compression or shear), tire, and rubber block that are all designed to transmit torque and accommodate some level of misalignment. The elastomeric inserts in these couplings can be changed to different grades to accommodate increased torque, temperature, and vibration damping to suit your application needs.
What is an elastomeric connector?
An elastomeric connector is a flexible component made from elastomer materials that helps transmit motion or torque while absorbing vibration and accommodating movement between connected parts. In rotating equipment applications, elastomeric couplings act as an elastomeric connector to improve equipment protection, reduce shock loads and support smoother system operation.
