The Servoflex couplings are available in a variety of models, characterised by high flexibility and high torsional stiffness. They are ideal for reliable and precise positioning at high speeds. The shaft coupling design has been successfully used in various applications. In all product placements the shaft coupling has proven to be very reliable, delivering cost effective torque transmission.
Extremely light, torsional stiff and flexible coupling
The SFC Model is a disc-spring coupling that use a lightweight, high-strength aluminum alloy for the clamp hub to enable high torsional stiffness and high response. Both, single-element types with high torsional stiffness and flexible double-element types that separate double elements with a spacer are available. Both lower the moment of inertia by linking the outer diameter of the hub to the shaft diameter.

Properties
Accurate positioning
These couplings utilise sets of optimised disc springs to transmit torque through steel clamp hubs. Their torsional stiffness is extremely high, their shaft rotation is accurate, and control can be ultra-precise. Both single-element types with ultra-high torsional stiffness and flexible double-element types that separate double elements with a spacer are available.
Properties
Modular construction to fit every application
These couplings utilise sets of optimised disc springs to transmit torque through steel clamp hubs. They are the basic type of SERVO FLEX. Single-element types with high torsional stiffness, flexible double-element types that separate double elements with a spacer, and floating shaft types that combine double elements with intermediate flanges are available.
Highly precise control
These couplings utilise sets of optimised disc springs to transmit torque through steel clamp hubs.. This makes them optimal for ordinary feed shafts that have high torsional stiffness, have accurate shaft rotation, and are capable of ultra-precise control. Both single-element types with high torsional stiffness and flexible double-element types that separate double elements with a spacer are available.
High speed rotation models
These models were developed to be compatible with spindle applications on machine tools. They are disc spring couplings capable of high precision and high speed. To enable high-precision mounting, both the flange unit and the pressurization flanges are equipped with centering mechanisms. They are also shaped so that the flange covers the periphery of the disc spring with few raised or lowered surfaces to minimize whistling during high speed rotation. Both single-element types with ultra-high torsional stiffness and flexible double-element types that separate double elements with a spacer are available.
The high-torque versions
The maximum size with disc spring couplings for high-output applications is an outer flange diameter of 262 mm and rated torque of 8000 Nm. Single-element types with high torsional stiffness and flexible double-element floating-shaft types that connect double elements with an intermediate floating shaft are available. The floating shaft is particularly able to handle the setting of lengths according to customer requirements.
