NORD’s robust MAXXDRIVE industrial gear units deliver high-torque solutions and flexible integration to handle the toughest jobs.
MAXXDRIVE® industrial gear units from NORD DRIVESYSTEMS are built to handle demanding applications such as bucket elevators, agitators, conveyor drives, mixers, cranes, hoists, crushers, and more. They deliver output torques from 132,000 to 2,495,900 lb-in, offer numerous input and output options, and are available as parallel-shaft helical gear units or right-angle helical-bevel gear units for flexible integration across a wide range of systems. Their robust UNICASE™ housings ensure excellent load capacity, long service life, longer bearing life, and quiet operation.
MAXXDRIVE® XC Parallel and Right-Angle Industrial Gear Units
Standard, compact MAXXDRIVE industrial gear units include MAXXDRIVE XC parallel industrial gear units and MAXXDRIVE XC right-angle industrial gear units. Parallel versions offer 11 case sizes to choose from, 2- and 3-stage gear reductions, a power range of 2.0 to 8,075.0 hp, and a torque range of 132,800 to 2,495,900 lb-in. Right-angle versions also have 11 case sizes available in 3- and 4-stage gear designs, a power range of 2.0 to 2,850.0 hp, and a torque range of 132,800 to 2,301,200 lb-in. Both versions feature multiple mounting options, cooling and heating options for flexible temperature management, and various sealing options for easy adaptation to a wide range of ambient conditions. For applications such as agitators or mixers that require increased bearing load capacities and additional oil leak protection measures, a dry cavity and spread bearing design with reinforced output bearings is available. Drives can additionally be equipped with sensors that monitor the operating state of the drive, including oil level sensors, temperature sensors, oil pressure sensors, vibration sensors, and leak indicators.
MAXXDRIVE® XT Right-Angle Industrial Gear Units
MAXXDRIVE XT industrial gear units are designed for high-speed applications requiring significant thermal ratings. These 2-stage, right-angle gear units offer 7 case sizes, performance up to 2,825.0 hp, and a torque range of 132,800 – 663,800 lb-in. Their unique finned housing design quickly dissipates heat while an axial fan and air guide covers enhance airflow to prevent the unit from overheating even at maximum power. These effective cooling abilities make them a reliable solution for environments with demanding ambient conditions and large temperature fluctuations such as those in bulk material handling and grain. The right-angle housing additionally enables a symmetrical configuration for mirror-image installations to reduce the number of replacement gear units and mounting on a swing base for a unified base frame with the gear unit and motor.
MAXXDRIVE® XD Parallel Industrial Gear Units
NORD developed MAXXDRIVE XD parallel industrial gear units to accommodate the specialized needs of crane and hoist applications. They feature an increased center distance by 35%, allowing the motor and rope drum to be on the same side of the gear unit in a unique U-shaped arrangement ideal for lifting drives. These units offer 12 case sizes, 3- and 4-stage gear reductions with the same footprint dimensions, power up to 3,084.0 hp, and torque up to 2,496,000 lb-in. MAXXDRIVE XD housings are additionally FEA-optimized for overhung load, especially downwards forces, and include an inspection cover on top of the unit for easy maintenance and service access.
MAXXDRIVE® XJ Right-Angle Industrial Gear Units
MAXXDRIVE XJ right-angle industrial gear units feature a special J-shaped shaft arrangement that is built to deliver high performance in small, compact installation spaces, making them ideal for traveling drives and material handling. They offer 12 case sizes, 3-stage gear reductions, a power range of 4.0 to 2,414.0 hp, and a torque range of 60,200 to 1,947,100 lb-in. Like MAXXDRIVE XD units, MAXXDRIVE XJ units also have a housing engineered for high external loads and an extended center distance design. They additionally offer various options, including drum couplings, brake attachments, solid or hollow shaft designs adaptable to application dimensions, foot mounting or shaft mounting, and belt drive synchronization.
In addition to the wide range of configuration options, NORD also offers an Endurance Package that consists of protective measures that optimize drive performance, maintain system reliability, and extend the service life of drive components in harsh environmental conditions, such as those in the Grain Industry. The main features of the package include a drying agent filter, oil sampling point, oil inspection glass, quick fit filter trolley connection, and an additional quick fit filter trolley connection with an oil drack cock. Together, this package combines multiple drive options into one comprehensive solution.
NORD recently unveiled an update to the myNORD online customer portal that allows registered users to configure MAXXDRIVE industrial gear units in the system themselves. Users can select XC, XD, XT, and XJ MAXXDRIVE designs with a solid input shaft and NEMA or IEC adapter. As only the first step in online tool expansion for the MAXXDRIVE product family, NORD plans to add more options in the future, including MAXXDRIVE gear units with motors.
