Redi-Rail ® Compact Precision Drawer Slides<br />
Linear Motion Systems<br />
PRODUCT OVERVIEW<br />
The very compact RDQ drawer slides are designed for<br />
High-Tech telescopic applications with precise motorized<br />
movement, requiring constant smooth sliding performance<br />
with no play.<br />
The squared designed is obtained by using two RRT-rails with<br />
hardened honed raceways, as the rigid intermediate element,<br />
into which the slides are assembled. The RDQ drawer slides<br />
offer both high radial and axial load capacities.<br />
The rail/slide configuration allows the RDQ drawer slides to be<br />
mounted not only at the side, but also underneath the moving<br />
part, when there are space limitations at the sides, or to be used<br />
in typical vertical applications. See below tables and figures.<br />
In the case of horizontal panel extension, we recommend the<br />
use of a pair of RDR and RDQ, as the RDR can absorb some<br />
lateral structural misalignments on the vertical axis.<br />
RDQ system assures smooth extension for all kinds of<br />
automation applications with variable telescopic strokes,<br />
which until now have been troubled by common friction<br />
breakdown problems, during the ball-cage rephasing, when<br />
using typical drawer slides. Same rephase problem or<br />
even deformation of the ball-cages, occurs for all vertical<br />
applications, as the ball-cage in such drawer slides, constantly<br />
tend to move downwards, so extra friction is generated with<br />
each stroke, during the repositioning of the ball-cages.<br />
To assure maximum load capacity the drawer slides must<br />
be correctly orientation, assembled. The extended part must<br />
always be fixed to the shortest slide.<br />
All Redi-Rail ® Steel Rails guarantee maintenance free<br />
operation, thanks to strong raceway wipers and longitudinal<br />
seals for dust and impurity protection, and an integrated<br />
lubed for-life greasing system, assuring a constant thin layer<br />
of lubrication on the raceway surfaces.<br />
All Redi-Rail ® Compact Precision Drawer Slides are<br />
equipped with internal end-stops, only designed to drag the<br />
intermediate element. It is therefore highly recommended not<br />
to use these internal end of stroke travel limits as functional<br />
terminals; strong external end-stops must be added. Similarly<br />
to the RDR series, the RDQ’s stroke goes slightly beyond the<br />
overall length of the rail in closed position. The rails come<br />
with an overall black finish.<br />
