Lets Talk about VIP
VIP indentification is stamped
on every chain link.
Chains stamped VIP are manufactured
with tighter tolerances
in the inner width. Also
they are permanently powder
coated with a fluorescent pink
colour.
A foolproof chain connection is
ensured due to the special fork
head design.
8S
BG-Approval (German
Statutory Authority)
The BG awarded for the RUD
Special Quality VIP is stamped
in short distances on the chain
links. H1 indicates manufacturer's
number. 1 = RUD.
8S means special quality,
higher than quality grade 8.
Quality Verification
At regular intervals chains are
stamped with the serial number
and the batch number. This
identification guarantees a
continuous record of manufacturing
and proof data, for
a period of 10 years.
We guarantee our VIP-Quality.
Overheating indication
The special fluorescent pink
powder coating permanently
changes colour at increased
temperatures. Colour black
signifies an application at more
than 400° C (716° F). Further
use is then prohibited.
The high quality VIP chains and
components have a Duplex
surface protection. Due to the
two stages, i.e. pretreatment
and pink powder coating, a
considerably better surface
protection is obtained compared
to normal zinc plating.
On request the super corrosion
coating Corrud® DS can be
supplied. This coating is 20
times more red rust resistant
than zinc plating.
Geometric construction and
tolerances of VIP-chains are
adapted to a higher quality
class.
The high-dynamic strength of
the VIP Mecano and the VIPchains
are beyond the standard
values. (min. number of cycles:
20.000). The upper load of the
VIP- components is 1.5 times
the VIP-WLL.
Simple examination of the
chain condition (wear and
elongation) can be undertaken
using the VIP-identification
tag.
VIP-Special Quality is a further development of the
RUD-Mecano Quality Grade 8,
which has been well established
for more than 20 years.
VIP = verwechslungsfrei =
V = fool-proof / I = in / P = pink.
Higher WLL: up to 30 % more
than the highest existing
quality Grade 8. Material: CrNiMo-special steel,
special quenching and tempering,
high toughness, min. ultimate
elongation for natural
black > 25%, surface treated
> 20%. Less sensitive to
notching and hydrogen
embrittlement than quality
Grade 8. The bending test acc.
to standard specifications of
DIN 5687-8 or EN 818-2,
ben-ding min. f = 0.8 X d, is far
exceeded. WLL: manufacturing
proof load:breaking force =
1:2,5:4.
Owing to a special heat treatment
developed by RUD, highdynamic
RUD VIP- chains are
more insensitive to external
mechanical wear friction and
to damage. Therefore a longer
lifetime of VIP- chain is guaranteed.
All RUD-VIP components are
electromagnetically crack
detected to ensure even
greater safety.
For chain sizes bigger than Ø 18mm one size smaller
can be used for the same WLL.
Example application 
The RUD fork head system,
well-established for decades,
continues in the new VIP program
(verwechslungsfrei =
foolproof in pink). The RUD
fork head system results from
its dimensional adjustment and
colour (VIP chains and components
in pink) in foolproof
connection of the correct
nominal VIP chain size.
Dim. X avoids connection of a
larger VIP- chain. VIP-stamped
chains are manufactured with
tighter tolerances in the inner
width (dim. W1). Dim. Y avoids
the connection of the next
smaller VIP-chain.
Result:
Only VIP chains and components
having the same working
load can be used.
Fitting
Hammer in tensioning sleeve so that the slot of the tensioning sleeve can be seen from the front. Use tensioning sleeve only once!
VIP-Foolproof assembly in mecano system
Patented: VG-bolt of a smaller size will drop out. 
Please note:
VIP-chains 8S can
only be connected
with VIP-components
8S.
VIP-components must
not be connected with
chains of lower quality
classes!
Use only original VIPcomponents!
VIP Overheating Indication EURO Patent EP 677681
The special fluorescent pink powder coating permanently highlights the maximum temperature at which the VIP-chain has been used. The pink colour changes to black when the chain is used at more than 400° C (forbidden). Coating starts to bubble. Replace VIP-chains or return them to supplier for repair.
