RINGFEDER® Elastomer Jaw Couplings GWE, TNM, TNS and TNB

The world-leading Elastomer Jaw Couplings of the RINGFEDER® series meet the highest performance and durability requirements in a wide range of sectors like the steel and metal industry, drive and conveyor technology, power generation, machine tool, packaging and printing machine construction as well as automation, control and positioning technology.

Available series are:


RINGFEDER® Metal Bellows Couplings GWB

Highly precise, torsionally stiff, backlash-free – the world's leading metal bellows couplings of the RINGFEDER® GWB series are ideal for all applications in which torques or rotary movements must be transmitted from shaft to shaft with highest angular accuracy: In linear and spindle lifting units of machine tools and packaging machines, in medical and pump technology, in test benches, in automation, conveyor and control technology, in robotics and much more.

Available series are:


RINGFEDER® Gear Couplings TNZ

Torsionally rigid and low-backlash gear couplings of the RINGFEDER® TNZ series are made of high-strength steel and are proving themselves worldwide in all industrial sectors where extraordinarily high torques must be transmitted from shaft to shaft.

Available series are:


RINGFEDER® Barrel Couplings TNK

High-quality RINGFEDER® Barrel Couplings of the TNK series are used in cranes and hoists to optimally connect the drive shaft of the gearbox with the rope drum. Further areas of application are lifting platforms, platform hoists and winch conveyors of all kinds. RINGFEDER® barrel couplings are torsional rigid, easy to assemble and maintain and effectively compensate for axial and radial shaft misalignments.

Available series are:


RINGFEDER® Flange Couplings TNF

Compact, highly robust, easy to assemble and maintain: The versatile and flexible RINGFEDER® Flange Couplings of the TNF series are used to reliably establish a backlash-free connection between two shafts by means of frictional locking. They are the more efficient and economical alternative to conventional press fits.

Available series are:


RINGFEDER® Torsional Highflex Couplings TNR

Innovative, non-shiftable Torsional Highflex Couplings of the RINGFEDER® TNR series allow for the flexible adjustment of dynamic torsional spring stiffness – and thus a smoother start-up and a vibration-optimised operation of the entire drive train.

Available series are:


RINGFEDER® Safety Couplings TNT

Highest safety for extreme requirements: Our mechanical safety couplings of the RINGFEDER® TNT series are specially designed for overload protection in the heavy-duty industry. If a pre-defined torque limit value is exceeded, the coupling halves and thus the input and output sides are separated quickly and reliably. The couplings operate according to the proven ball catch principle.

Available series are:

  • TNT 2420
  • TNT 2424
  • TNT 2425
