NORD industrial gear units have been developed according to the tried-and-tested unicase housing principle. The unicase is a one-piece housing, into which all the bearings are integrated. The finishing of this unicase is carried out with in unique jig, on state-of -the-art CNC machines. The unicase concept features highest levels of precision, rigidity and strength. There are no dividing seams between the drive and the gear unit housing which are subjected to transverse forces or torque. The unicase principle allows the shaft axes to be staggered, resulting in a more compact design which allows the use of larger roller bearings to guarantee a long operating life.

Advantages of unicase housings:

• Optimum sealing
• Quiet running
• High torque capacity
• Increased lubricant life
• Maximised operating life of bearings and gears
• High reliability
• Long operating life
• Symmetrical design
• B14 face as standard on output side
• 6 installation confi gurations
• Mirror-image installation possible
• Same housing size, installation dimensions for all ratios (2 and 3 stage)
