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 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
High dampening performance with high precision
The Servoflex SFR Coupling uses a HNBR rubber element to provide a higher amount of vibration dampening than comparable disc pack couplings. It does so whilst retaining a high level of precision and performance with zero backlash and strong torque transmission.

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 and double-element types are available, with an option of conical and regular clamping hubs.
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. Singleelement types, double-element types that separate double elements with a spacer, and floating shaft types that combine double elements with intermediate flanges are available.
Properties
Highly precise control
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 and double-element types are available.
Properties
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.
