We
are pleased to introduce our new range
of HighForce Precision Planetary Rack & Pinion Drive Systems. There are three
different planetary drive systems available, with helical or straight
(spur) rack & pinions, to meet any application requirements.
HighForce ZTRS:
 For
ultra-precise applications with thrust forces up to 28,000 lb., the
HighForce ZTRS rack & pinion drive systems are very well suited. These
drives, which are available in five sizes with backlash levels down to
one arc-minute, can handle highly dynamic and heavy loads. They utilize
precision planetary reducers with an integral output housing and
outboard bearing to provide a rigid support of the output pinion.
By
adding an output bearing housing, the tilting moment capacity of the
flanged planetary reducer is dramatically increased. Also, the unique design of the pinion allows for smaller pitch
diameters, which decreases the torque on the reducer. Because of these
design enhancements, a smaller reducer can typically be used.
HighForce ZTR & ZR:
 For
precise applications with thrust forces up to 12,000 lb., the
HighForce ZTR and ZR
rack & pinion drive systems are now available. These drives, which are
available in seven sizes with backlash levels down to one arc-minute,
are similar to the ZTRS drive systems but without the outboard bearing
support.
The drive pinions are flange mounted to the reducer output,
providing tight integration of the driven load, while allowing
replacement of the pinion if needed.
For
more economical and lighter duty applications with thrust forces up to
4,500 lb., planetary reducers with solid output shafts are also
available for mounting bored pinions directly via keyways or compression
couplings.
These
drives are perfect for a wide range of applications, such as traveling
gantries & columns, pick & place robots, machine tools, CNC routers and
material handling systems. Zero backlash rack & pinion drive systems
are also possible by using two reducers to share driving the load during
acceleration while removing the axis backlash to ensure precise
positioning. Applications for these systems can be found in the
Material Handling, Automation, Aerospace, Woodworking, Machine Tool and
Robotics industries.

There are
three levels of precision for the hardened & ground racks, with rack
pitch error ranging from 0.012 mm to 0.036 mm per meter length depending
on which rack is used. Follow this link for more information on

HighForce ZTRS System Specifications: |
Our
HighForce ZTRS rack & pinion drive systems
utilize our
Precision Planetary Reducers with an ISO
9409-1 output flange
and are available in five sizes with backlash levels down to
one arc-minute, can handle highly dynamic and heavy loads. They utilize
precision planetary reducers with an integral output housing and
outboard bearing to provide a rigid support to the output pinion.
The maximum drive force that each system
can handle (with safety factor 1.0) is listed below; this should be
compared to the application peak force, which can be
calculated here

HighForce ZTR &
ZR
System Specifications: |
Our
HighForce ZTR & ZR Rack & Pinion Drive Systems utilize our
Precision Planetary Reducers with an
ISO 9409-1 output flange to provide a rigid support for a hardened
& ground helical pinion. This provides tight integration of the
driven load while allowing replacement of the pinion if needed. These
systems are available in seven sizes with backlash levels
down to one arc-minute and ratios from 4:1 to 100:1.
The maximum drive force that each system
can handle (with safety factor 1.0) is listed below; this should be
compared to the application peak force, which can be
