UNICASE worm gear units – More torque for the same size

The drive experts from NORD DRIVESYSTEMS have increased the torques of their UNICASE worm gear units, thus omitting the switch to the next size depending on the application.

NORD successfully increased the performance of its UNICASE worm gear units of 10 to 15 percent without altering the outer (connection) dimensions or the overall visual appearance. To save installation space, smaller sizes can now be selected depending on the application. “With the higher torques of our UNICASE worm gear units, accompanied by an increase in performance, we could generate tremendous added value without any additional costs for our customers”, Jörg Niermann, Head of Marketing, emphasises. “We owe this to the extensive technical know-how as well as the long-term experience of our competent development team.”

A masterpiece of engineering skill

To achieve higher power ranges, NORD has introduced new worm shafts with larger bearing seats as well as an additional reinforcement of the worm wheel itself. The current UNICASE worm gear unit series now offers a power range from 0.12 kW to 15 kW, and torques between 90 Nm and 3,000 Nm. Other product advantages include smooth and quiet running, high overload capacity and robust design. High axial and radial loads ensure high operational and system reliability and long service life.

The UNICASE worm gear units in cast iron housings are available in application-specific versions as hollow and solid shaft gear units, and for shaft, flange or foot mounting. NORD´s electric motors can be added as an integrated solution. Motor mounting via an IEC/NEMA adapter is also possible.
