Backlash-free servo couplings / shaft couplings

Our servo couplings are torsionally stiff shaft couplings soft in bending serving as a connection element between drive unit and measuring sensor. They transmit the torque free from backlash and conformally, making our backlash-free shaft couplings highly accurate. They also allow for compensation of radial, axial and angular displacements. Thanks to the high variety of coupling types and hub designs we are able to supply the right coupling for almost every application.

Our range of backlash-free servo couplings (backlash-free shaft couplings) includes jaw couplings (ROTEX GS), metal bellow-type couplings (TOOLFLEX), servo laminae couplings (RADEX-NC) and shaft encoder couplings (COUNTEX).

ROTEX® GS backlash-free servo couplings
Low-priced, backlash-free servo couplings - easy and quick assembly

ROTEX GS is a three-part servo coupling (elastomer coupling) backlash-free under prestress. The different hub types and various kinds of Shore hardness provide the optimum coupling for every application in automation technology.

TOOLFLEX® metal bellow-type couplings
TOOLFLEX is a torsionally stiff and flexible metal bellow-type coupling (all-metal coupling) with a bellow made of stainless steel and coupling hubs made of aluminium. The coupling hubs of our metal bellow-type coupling in size 55 and 65 and as a type KN are made of steel.

RADEX®-NC backlash-free servo laminae couplings
The servo laminae coupling RADEX-NC was developed for applications in servo technology.

The package made up of torsionally stiff and flexible steel laminas offsets axial, angular and radial shaft displacements. Being an all-metal coupling - the laminas are made of stainless steel - the RADEX-NC can be used with temperatures up to +200 °C and under aggressive ambient conditions.
