The new generation of KettenWulf LF “Lube Free”
chains is based on the manufacturing technology and
material of the standard KW chain.
In addition to the standard features, this chain is
characterised by a special oil-impregnated sintered
bush which forms a particularly wear-resistant and
long-lived chain link in combination with the unique
smoothness and hardness of the specially treated
pin.
Since the special lubricant for sintered bearings will
only escape from the bush when exposed to friction
and temperature, these roller chains are delivered
with a thin layer of initial lubrication. In order to ensure
a very high level of corrosion protection, all components
are plated with nickel, in addition.
The operating temperature range of the chains is
between -30°C and +160°C. LF chains are available
for an extended temperature range upon request.
The functional dimensions are those stipulated in
ISO 606. Furthermore, KettenWulf LF roller chains can
be delivered with straight link plates. These are ideally
suited for pallet and skid transport.
Made-to-order KW LF chains can also be produced
on the basis of the KettenWulf TGI chain. This version
is best suited for all critical applications requiring
particularly high fatigue strength, maximum corrosion
protection and a special resistance to highest
speeds.

LF roller chains
1 Pins made of alloyed steel,
cold-extruded pins starting
from 1 ½" are made of highly
alloyed heat-treated steel,
nickel-plated with high
surface hardness and
particularly smooth grinding
2 Bush – self-lubricating,
oil impregnated bush
with special lubricant
3 Roller – seamless, cold-extruded
roller, through hardend, ball
blasted, extremely shock resistant
4 Link plates – high-precision
stamped, quenched and
tempered and subsequently
ball-blasted, holes calibrated
with particularly high percentage
contact area
All components are
nickel-plated for optimal
corrosion protection
