| Controlflex | Semiflex | Schmidt-Kupplung | Servoflex | Loewe GK | Omniflex The axially-stiff coupling Axially fixed Anodised clamp hubs Use of high-performance plain bearings The coupling with high axial stiffness The Loewe GK is an axially stiff coupling for transmitting torques while absorbing axial push and pull loads without changing its length. Thus, it is also able to perform guiding tasks in axial directions. By combining kinematic properties, it also enables high radial and angu- lar displacements. The Loewe GK is also perfect as a linear coupling for the precise transmission of...

| Controlflex | Semiflex | Schmidt-Kupplung | Servoflex | Loewe GK | Omniflex Technique High power density Loewe GK uses self-lubricating heavy-duty slide bearings with highest pressure and wear resistance, thus ensuring optimised mechanical properties of the coupling. When in conjunction with coupling pins optimally tailored in tolerance and material as counter elements, coupling backlash as well as friction and wear rates are minimised. In addition, slide bearings have very high thermal resistance. Thus, the Loewe GK coupling operates at constant temperature of -20° to +150°. Axially...

| Controlflex | Semiflex | Schmidt-Kupplung | Servoflex | Loewe GK | Omniflex Selection sequence Torque 1. Friction power If speed, torque and offset occur together, a friction power specifically related to couplings must not be exceeded: TA (Nm) * RA (mm) * nA (min-1) PRA = D (mm) * 60 PRA = Friction power, TA = Torque of the application, RA = Offset, nA = Speed, D = Coupling diameter PRA< PRN The calculated friction power of the application PRA must be smaller than PRN the rated friction power in the table. Individual catalogue data should not be exceeded. The permanent service...

| Controlflex | Semiflex | Schmidt-Kupplung | Servoflex | Loewe GK | Omniflex Installation General Loewe GK are delivered ready-tomount with the desired bore diameters. During installation, please observe the permissible displacement values. Due to design-related reasons, the Loewe GK performs no axial displacement. Installation The shaft ends and hub bores to be connected must be clean, dry and burr-free. Check shaft connection dimensions (also feather key dimensions) and tolerances. For installation, the Loewe GK is fully pushed onto the motor stub shaft. Bores are supplied in fit F9....
