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.

The metal bellow ensures optimum compensation of axial, radial and angular displacements with conformal torque transmission. At the same time the geometrical shape of the metal bellow-type coupling provides high torsion stiffness and a low mass moment of inertia. Apart from that it is resistant to media effects and critical operating conditions.

Metal bellow-type coupling for drive technology, automation technology, medical technology, servo drives, packaging technology, machine tools, etc. For the different applications and mounting conditions of the TOOLFLEX metal bellow-type couplings two different bellow lengths are available.

• Backlash-free, torsionally stiff bellow-type coupling made of metal
• Maintenance-free
• Shear type
• Ambient temperatures up to 200 °C possible (depending on size)
• Torques from 0.1 to 600 Nm
• Couplings for drive technology, automation technology, medical technology, packaging technology, machine tools

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 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.

It is used wherever drives have to position accurately. In spite of their vibration-damping properties the coupling is torsionally stiff so that you do not have to cut back on precision even with highly dynamic servo drives. The ROTEX GS backlash-free elastomer couplings allow for simultaneous compensation of radial, axial and angular displacements.

The backlash-free servo coupling ROTEX GS uses the construction kit system, it is available in a high variance of different hub types which can be combined within one coupling size.

The choice of the hub material depends on the size and the hub is either made of aluminium or steel. Both frictionally engaged connections without feather keyway and positive-locking connections with feather keyway are available.
