Gearboxes
Lenze Helical Gearboxes
GST helical gearbox/geared motor
The excellent performance of these 3 and 4-stage integrated right-angle gearboxes sets them apart. Thanks to the robust cast iron housing, high permissible torques and closely stepped speed reduction ratios, they can meet even the most stringent of requirements.
The gearboxes/geared motors are used in the following areas:
- Materials handling technology, logistics, transport
- Industrial handling
- Packaging technology
- Building materials industry
- Stage machinery

Drive-end versions
- Integrated three-phase AC motors
- IEC motor adapter
- Free shaft input
Output-end versions
- Hollow shaft with keyway or shrink disc
- Solid shaft with keyway
- Foot or flange mounting
- Torque plate with rubber buffer
GFL shaft-mounted helical gearbox/geared motor
These 2 and 3-stage parallel-axis gearboxes are primarily used as shaft-mounted gearboxes. The gearbox has a space-saving design and is easy to mount. As well as enabling internal power or torque sharing, the output shaft is accessible for further use (e.g. for installing encoders).
The gearboxes/geared motors are used in the following areas:
- Materials handling technology
- Process engineering
- Plastics
- Food, beverages and tobacco industries

Drive-end versions
- Integrated three-phase AC motors
- IEC motor adapter
- Free shaft input
Output-end versions
- Hollow shaft with keyway or shrink disc
- Solid shaft with keyway
- Foot or flange mounting
- Integrated torque plate with rubber buffer
GKK bevel gearbox/geared motor with clutch
For monorail overhead conveyor drives (EMS).
The 2-stage helical-bevel gearbox with disconnect clutch, with its compact dimensions and high radial power capacity, is particularly well suited to materials handling applications.
When combined with a Lenze motor control unit, these products make for optimum automation of in-plant drive tasks. Only low force is required in order to isolate the drive from the output end; disconnecting drives from the process becomes child's play.
In conjunction with the OCU decentralized motor control unit, Lenze offers a complete drive system for monorail overhead conveyors.
The gearboxes/geared motors are used in the following areas:
- Materials handling technology
- Automotive industry

Drive-end versions
- Integrated three-phase AC motors
Output-end versions
- Solid shaft with keyway
- Foot or flange mounting
GKR bevel gearbox/geared motor
The alternative to worm gearboxes.
This 2-stage, right-angle gearbox for use in low to medium applications is characterized by its high efficiency, lightweight design (thanks to the aluminum housing) and wear-free gear teeth.
With Lenze bevel gearboxes/geared motors, you will benefit from lightweight designs and low life cycle costs - they are efficient, economical and fit for the future!
The gearboxes/geared motors are used in the following areas:
- Materials handling technology, logistics, transport
- Industrial handling
- Building services engineering including air conditioning
- Packaging technology
