Slewing ring drive packages now from one source

Slewing rings carry large axial, radial and moment loads within a compact dimension 
envelope and are used in a wide range of industrial machines. Their use offers an
elegant 
solution to the problem of load carrying, stability and power transmission.

This approach fits well with a planetary gear assembly and as such NBC Group has 
joined forces with Rossi Gear Motors Limited UK to offer complete solutions in any
slewing 
applications. Both companies will work together to deliver an engineered
solution for slewing gear 
application through NBC.

NBC group currently design, manufacture and stocks a comprehensive range of 
slewing rings while Rossi UK with the investment in local assembly of the modular
Rossi planetary range allows for a rapid solution built around experience and
technical 
know how.

Rossi UK continues to develop its service offering in order to provide a comprehensive
service and planetary product range. With the release of the new EPS slewing range 
from its parent company Rossi Spa of Italy it now has the ability to offer the market a
viable alternative to primary drives mechanisms for slewing rings.

The new EPS range is principally made up of 4 output designs across each output
stage 
up to a torque range of 250,000Nm. Utilising the modular gear set components
from 
the standard catalogue the range allows for primary drives systems be they
hydraulic, 
electric or other. The four output designs are built around an integral pinion
shaft, however 
based on the modularity of the product range an external pinion gear
can be fitted to a 
splined male output shaft. All output units will be optimised for
eccentricity to allow for 
correct interfacing between the pinion and the slewing gear
itself.

NBC Group manufactures slewing rings and slew drives under the brand name of
QCB® 
and offer direct equivalents to other global slewing brands. NBC Group carries
a wide range 
of stock of up to 2 000mm diameter and can custom design any for ball,
x-roller, angular contact, double row, triple row or even wire race bearings up to 15 000mm
outside diameter.

Together both Rossi and NBC utilizing their individual product range and experience
believe 
this partnership sets them apart from many "number traders" in this market.

With certification such as ATEX or even DNV being available for both the slewing
and planetary
units, the applications are no longer limited to isolated applications. 

NBC already supplies slewing rings for aerospace and military applications, high
radiation area nuclear handling 
equipment, large diameter offshore applications
and many other "specials" including split 
slewing rings. The inclusion of a principle
drive package allows for turn key projects with 
the backing of one of the fastest
growing planetary brands at the moment.
