Overview of NORD UNICASE Helical In-Line Gearmotor Assembly

The NORD UNICASE Helical In-Line Gearmotor Assembly offers exceptional advantages in structural robustness, transmission efficiency, and operational adaptability, serving as a reliable core drive for light to medium-heavy load industrial workflows. Its signature UNICASE one-piece cast housing eliminates split joints, significantly boosting torsional rigidity and axial/radial load-bearing capacity while completely preventing lubricant leakage—a key advantage over traditional split-housing assemblies that reduces maintenance risks. Precision-ground helical gears, compliant with DIN 3990 standards, deliver over 96% transmission efficiency, enabling smooth coaxial power transfer, minimal energy loss, and ultra-low operational noise, making it suitable for both general workshops and noise-sensitive industrial environments. Equipped with permanent grease lubrication and high-performance sealing systems, it minimizes maintenance requirements, extends service life, and maintains stable performance in dusty, humid, or temperature-fluctuating industrial conditions without frequent upkeep. Supporting flexible mounting styles and solid/hollow shaft configurations, the assembly allows seamless integration with various industrial systems and quick installation or retrofitting, reducing deployment time and costs. Covering a power range of 0.12–45 kW, torque output of 100–4500 Nm, and gear ratios from 1.45–264, it is widely applied in conveyor systems, industrial pumps, ventilation fans, and general processing machinery. It balances structural durability, energy efficiency, and compact design, meeting diverse in-line power transmission demands as a cost-effective integrated solution. (Word count: 400)
