NENCO's Complete Development Programme (DP)

Servodisc are the backlash free all metallic disc couplings designed for servo motors to offer precise positioning with high reverse loads. The servo series are manufactured from a high strength low weight alloy for precise motion control. 

SERVODISC-Backlash free Disc Couplings

NENFLEX elastic couplings are on the market since 1985 and are available in
several design combinations to connect two rotating shafts to transmit torques from
a minuscule 5 Nm to 80,000 Nm.

NENFLEX- Elastic Couplings, Industrial.

Backlash free elastic couplings are designed with a pre-stressed
elastomeric arm having a special profile that is sandwiched between the
driver and driven jaws, to provide a backlash free connection
with high degree of positioning accuracy.

SERVOSTAR- Elastic and backlash free coupling.

Since the acquisition of its first patent in 1991 for improvements in frictional shaft hub technology, NENCO has offered countless solutions to lock a cylindrical shaft and hub frictionally for diameters from Ø 6mm up to Ø 500mm.

MECALOC- Keyless shaft hub locking devices.

SPIREX- Encoder Couplings

With design options of a single disc for slow speed to twin discs for high speed, torque and misalignment capabilities, our portfolio includes a wide range of designs from 80 Nm to 500,000 Nm torques with variable options.

FlexiMax- Torsionally Stiff Disc Couplings

On a test bench, the torque transducer needs to be connected to the driver and the driven equipment accurately through a torsionally stiff coupling system that can operate at high speeds, and accommodate for the three misalignments.

MEZURDISC- Couplings for Measurement of Torque
