Redi-Rail ® Precision Drawer Slides
Linear Motion Systems
PRODUCT OVERVIEW
The RDR Redi-Rail ® Precision Drawer Slides are designed for
heavy duty High-Tech telescopic applications, with precise
motorized movement, requiring constant smooth sliding
performance with no play.
The special smooth operating performance is due to doublerow
precision bearings strong rails with hardened and honed
raceways, fixed to a rigid intermediate S-shaped steel plate,
assuring high load capacities and low deflexion at even fully
extended position.
The PBC drawer slides assure unique self-aligning capability,
when used in pairs.
The right drawer slide RDRD, allows the slides to rotate
with no play, in the lower rail-element to compensate for
surface misalignments, while the rigid left RDRS drawer slide,
maintains a stable and precise extension. The RDR or
Redi-Rail ® Precision drawer slide system offers unique

possibilities and benefits for all kind of automation
applications with variable telescopic strokes, which until
now have been troubled by common friction and breakdown
problems, during the ball-cage rephasing when using of
old-type ball-cage drawer slides. To assure maximum load

capacity the drawer slides must be correctly positioned
according to the rollers’ positioning, which are non-symmetric
and with different position in upper – lower rail element.
Therefore the extended part must always be fixed to the lower
rail. All Redi-Rail ® Drawer Slides guarantee maintenance free
operation, thanks to strong raceway wipers and longitudinal
seals for dust and impurity protection, and an integrated lube
for-life greasing system, assuring a constant thin layer of
lubrication on the raceway surfaces.
All Redi-Rail ® Precision Drawer Slides are equipped with
internal end-stops, only designed to drag the intermediate
element. It is therefore highly recommended not to use these
internal ends- of stroke travel limits as functional terminals;
strong external end-stops must be added. The Redi-Rail ®
Lubrication system for full life-time.

Precision Drawer Slides load capacities are intended at half
extension (L/2) as indicated in by letter “P” in below drawing.
Unlike ball-cages drawer slides, the Redi-Rail ® Drawer Slides
maximum load capacities are based on continuously non-stop
operation.
Therefore a straight load comparison with other drawer
slides isn’t possible, as these load capacities are merely a
static load capacity, based on low daily frequency. To offer a
wide range of load capacities and extensions, the Redi-Rail ®
Drawer Slides come in 2 dimensions. The RDR80, based on
28mm rails with outer height of 80mm and RDR116, based
on 43mm rails, with outer height of 116mm. Both rails come
with an overall black finish.
