Offset helical gearbox, large axial distance and high-quality helical gearing.

The slim black wonder: Offset helical gearbox.

The offset helical gearboxes of the F series have a lot to offer. They feature an extremely space-saving design, a large axial distance, high positioning accuracy, and high efficiency.

BENEFITS
Compact, space-saving and absolutely powerful

Due to the extremely flat housing of this series and the large axial distance, offset helical gearboxes are perfect for integration in applications that have very tight, difficult space constraints.

Another plus is that offset helical gearboxes are extremely fast and easy to assemble.

For high demands on efficiency, ruggedness and service life

Due to their design, offset helical gearboxes belong to the helical gearbox family. Therefore, their advantages clearly lie in their high efficiency.

The high-quality helical gearing of the spur-gears also guarantees exceptionally smooth operation.

Due to the nature of their rugged housing, offset helical gearboxes also run with extreme reliability and fail-safe performance. This also makes them suitable for continuous operation.

High positioning accuracy and backlash stability

To meet higher precision requirements, the F series offset helical gearboxes are available in two backlash classes. The hardened helical gearing ensures reliable backlash stability.

F gearboxes are either available as compact servo, Lean or asynchronous offset helical geared motors or they can be attached to all common synchronous servo motors by suitable adapters.
