Worm gearboxes (SG) are noted for their very quiet running. The worm-gear shaft has bearings on both sides. The gear components, made of bronze or steel, and the lubrication ensure a long service life at the rated torque. In many applications, the location of the output shaft at 90° to the motor shaft provides an optimum design solution. On request, worm-gearboxes can be supplied with a hollow output shaft.

The patented “BOX” series is made with aluminium housing from size 25 up to 90.
The housing has been designed with parametric CAD SW supported by programs of analysis of the thermal dissipation capacity and the structural resistance/deformation under the effect of working loads.
The wormshaft is made in case hardened steel and ground machined, while the worm wheel is in shell cast bronze. Before being assembled, the worm wheel is submitted to a running-in working period to improve the surface finishing and hardness.
From type 63 and up, 2 taper roller bearings are mounted on the wormshaft.
The combination of this characteristic and 2 nilos permits the mounting of the whole BOX range, from the size 25 to the size 110, in the positions V5 and V6 without any need of additional interventions
The gear unit is equipped with a full set of filler, level and breather plugs, permitting all mounting positions and facilitating the management of the stock.
The sizes 25 up to 90 are supplied with long-life synthetic oil and they don’t require any maintenance
Mating surfaces are machined for a perfect planarity
A paint coat cancels the negative effects of the aluminium porosity and protects the housing from oxidation

Neeter Drive (a division of Power Jacks) offers a vast variety of Spiral Bevel Gearboxes in its four ranges, features from the various ranges include ratios up to 6:1, hollow shaft, speed increasing, motor mounting flanges, and light weight aluminium housings. The original range, now known as the Range N features fine tooth gears (greater overlap ratio), shouldered shafts, O-rings in all covers and supplied with double rounded keys in the customer end of the shafts.
The Range N could be key to over come or help in your design and applications. Over many years this range has been adapted to suit customer needs; whether it's a minor alteration, including longer or, shorter shafts or even a simple spigot on covers this can be achieved. The main advantage of the units specifically adapted to meet customers needs, is that they allow the units to easily and neatly interface with the end product, saving assembly time and cost.

Varvel continues to score successes in its product range completion with the new hollow output shaft speed reducers 'Series RN-RO-RV'.
Each size of this new series - displayed at the former Hannover Fair, April 2007 - is designed with a common base body that gives rise to three different speed reducer lines by the means of the appropriate input module fitting: RN shaft mount, RO horizontal and RV vertical input bevel/helical.
Speed reducers are designed in six sizes - aluminium pressure die cast for the smallest three and grey cast iron for the bigger ones - with 30 reduction ratios in two and three stages, and output torques from 180 Nm to 3200 Nm.
Multiple foot-, flange- or torque arm mountings are available as well as hollow output shafts (keyed, shrink-disk, splined) and solid simple or double sided.
Same fixing footprint for the three versions, high flexibility, easy mounting and quick lead times are the pluses that make the speed reducers RN-RO-RV a really new and advanced range.
