DELFLEX LF torsional coupling system

Characteristics and benefits

The basic component of the DELFLEX LF torsional coupling is the unique and highly versatile elastomeric element. This element can be easily mounted in a number of different ways according to the application, and without special design changes or complex hardware modifications. The element, which is available in different materials for optimum performance, is connected to a cylindrical hub with radial screws and then to a flanged hub by axial screws. This unique coupling design is remarkably simple, high effective, and gives the DELFLEX LF torsional coupling unmatched performance capabilities.

DELFLEX LF torsional flexible elements

The coupling elements are torsionally soft and are placed into compression during assembly. Rubber in compression can carry up to five times the amount of torque, as compared to non-compressed elements. The rubber DELFLEX LF torsional elements effectively accomodate shock, misalignment and vibration and do not exert harmful radial and axial forces on the connected equipment. Each rubber element material is available in various durometer hardness (Shore A Scale) of 50 and 60 for particular torsional vibration requirements. HTR high rubber elements have an operating range of -40 °C - 90 °C.
