CLASSIC WORM GEAR SCREW JACKS (C-SERIES)

The new NEFF classic product line of the C-Series Screw jacks prove to be modern high-performance screw jacks. They are technically robust and flexible in terms of application. This is insured not only by the integrated screw lubrictation, making a relubrication of the spindle drive during operation possible, but also by the high-performance gearing, that allows higher efficiency and longer duty cycles. Due to the separated lubrication systems of gear and screw jacks the new C-series screw jacks can be used in any desired installation position. They are provided with a high quality semi-fluid grease and lubricated for life unter normal circumstances. The housings which are optimized by using FEM (the finite-element-method) allows for a safe use even in case of extreme weights. Within the standard programm it is possible to chose different screw types and grades. Beside the use of single and multiple threads, ball screws with different pitches can also be chosen. In the case of manufacturing with ball screws, the ball screw nuts are completely integrated into the gear housing. Less mounting space is necessary. In addition to the catalogue standards, NEFF Gewindetriebe GmbH is constantly developing new drive solutions for customized projects on request.

TYPE R

SCREW JACKS C-SERIES - TYPE R

The C-Series Screw Jacks in R-Version is characterized by a rotation screw drive with lead nut. Through the rotating screw and the lead nut fixed with the technical environment a lift drive is affected. The Screw drive is axial fixed and moves not through the gear housing. In case of this the C-Series Screw Jacks can be assembled direct on the bases without take consideration for any installation space for the protective tube. The R-Version covers the advantage that there is lower heat development in the gear housing. That leads to higher duty cycle time at the same conditions. The C-Series Screw Jacks are available with trapezoidal and ball screw drives with different pitches and several lead nuts.

TYPE N

SCREW JACKS TYPE N - C-SERIES

The Screw Jacks of the C-Series in Version N are characterized by a heaving screw. These screws are available with trapezoidal and ball screw drives as well. In both cases the nut of the Screw drive will be integrated in the gear housing. Through the fix assembly of the screw end with the environmental construction the lifting drive is affected. The advantage of the N-Version is that minimal construction space is needed. On the opposite side of the gear housing a protection tube for the incoming screw is assembled. A further advantage of the N-version is that in applications with long strokes the nonrotating screw leads to no oscillation.
