UNICASE Helical Worm Gearboxes are angular gearboxes available in multiple stages where the motor shaft and the output shaft form a 90° angle. This allows for flexible mounting options where installation space is limited. The helical gears of UNICASE worm gearboxes are made of high alloy steel with case-hardened teeth. Optimized geometries and precise shaft alignment provide excellent load-bearing capacity, long operating life, and quiet operation.

The worm stage has a hardened cylinder worm as well as a worm gear with a special bronze rim welded to it. This combination ensures ultimate reliability.

UNICASE worm gearboxes are factory lubricated for life with high-quality, synthetic lubricant. This lubricant prevents friction, provides a high degree of efficiency, and further increases the life of these gearboxes.

NORD’s 2-stage SK 02040 UNICASE worm gearboxes have been redesigned as SK 02040.1 gearboxes. Made from high-strength aluminum or die-cast aluminum, these units guarantee maximum strength and rigidity in a lightweight, compact unit. Their universal mounting design offers significant customer advantages, including fast installation.
