The slim option for the long haul: Power transmission offset helical gear units.
The offset helical gear units of the F series have a lot to offer. They feature an extremely space-saving design, a large axial distance, and high efficiency.
And with a short STOBER adapter, they are ideally suited for attachment to all asynchronous motors!
Due to the extremely flat housing of this series and the large axial distance, offset helical gear units are perfect for integration in applications that have very tight, difficult space constraints.
Due to their design, offset helical gear units belong to the helical gear unit family. Therefore, their advantages lie in their high efficiency.
The high-quality helical gearing guarantees exceptionally smooth operation. This is an major advantage for use in continuous operation! Due to nature of their rugged housing, offset helical gear units also run with absolute reliability and fail-safe performance.
Using a short motor adapter, these gear units can be attached to standard or stainless steel motors quickly and easily in accordance with IEC or NEMA-C.
