General Product Description
New Runner Blocks for oil and
grease lubrication from above
FNS R1851 ... 16
SNH R1821 ... 16
The dimensions, load capacities, rigidity
and moment loads correspond to those
of standard runner blocks R18.. ... 10.
Special feature:
Runner blocks R18.. ... 16 have been
prepared for oil and grease lubrication
from above. In the high runner blocks
S.H, the vertical clearance between the
end caps and an attachment mounting
surface with integrated lube adapters
has been designed for ease of mainte-
nance.
FLS R1853 ... 16
SLH R1824 ... 16
How to recognize them:
The top lube holes at both ends have al-
ready been opened, but they are closed
with screws for shipment (O-rings for
sealing the lube fi ttings are provided with
the runner blocks).
New Runner Blocks (exclusive-
ly) for central oil lubrication via
dosing valves
FNS R1851 ... 17
SNH R1821 ... 17
The dimensions, load capacities, rigidity
and moment loads correspond to those
of standard runner blocks R18.. ... 10.
Special feature:
Runner blocks R18.. ... 17 have smaller
lube ducts. They need only small quanti-
ties of lube oil even when wall-mounted
and are therefore suitable for all mount-
ing orientations.
FLS R1853 ... 17
SLH R1824 ... 17
How to recognize them:
The end caps are gray. In the high runner
blocks S.H, the vertical clearance be-
tween the end caps and an attachment
mounting surface with integrated lube
adapters has been designed for ease of
maintenance. The top lube holes have al-
ready been opened, but they are closed
with screws for shipment (O-rings for
sealing the lube fi ttings are provided with
the runner blocks).
Runner block short names
FNS = Flanged, normal, standard height

Heavy Duty Runner Blocks
now also in size 100
Heavy duty steel runner blocks now also
available in size 100.
Options
Corrosion-resistant runner blocks, Resist
CR, matte silver hard chrome plated.
Part numbers: FNS R1861 2.. 60 or
FLS R1863 2.. 60
(Illustrations not to scale)
FLS R1863 2.. 10
New V-Guide Rails without
mounting holes
V-Guide Rail R1808 .1. 3.
Without mounting holes
Mounting with pressure pieces
Special feature:
The V-guide rails R1808 .1. 3. have no
mounting holes. Instead, pressure pieces
are used to push them up against an
inclined reference edge, align them and
fi x them in place.
Advantages:
Optimally smooth runner block travel,
since there are no mounting holes in
the guide rail
Improved straightness through
uninterrupted guide rail profi le
Smooth rail surface for optimal
sealing action
Cost-saving – only one row of holes
necessary for mounting and align-
ment
Number of pressure pieces can be
varied to match loads
Mounting base can be machined
using standard profi le milling tools





New Resist CR coating:
matte silver hard chrome
plated
Corrosion-resistant runner blocks and
guide rails in Resist CR, matte silver
hard chrome plated, replace the run-
ner blocks and guide rails with zinc-iron
coating.
Resist CR runner blocks and guide rails
come in accuracy class H; accuracy
classes P and SP on request.
One-piece Resist CR guide rails are
available in two versions:
End faces uncoated, on request in
some cases
End faces, chamfers and end-face
threads coated
In composite Resist CR guide rails the
joint faces are coated as well as the end
faces.

New codes for Roller Runner
Block preload classes
Preload classes
C1 = preload 3% C,
manufactured on special request
C2 = preload 8% C
C3 = preload 13% C
Wide and heavy duty runner blocks are
not available in preload class C1.
Please refer also to “Selection of System
Preload”.
