The KettenWulf TGI “Tri Guard Inchromised” coated
chain is suited for the highest requirements in corrosion
resistance, wear resistance and fatigue strength.
It represents the state-of-the-art standard on the
market for applications under hard-wearing and
aggressive conditions.
The materials and the manufacturing method used
are the same as for the KW HFS chain and guarantee
the same high level of fatigue strength.
In addition, all components receive a special Geomet®
coating. This type of coating achieves the unmatched
corrosion resistance level of more than 500 hours in
a salt spray test.
Compared to the HFS chain, the pin material has
been further optimised by a layer of chrome plating.
This gives the pin a particularly hard and smooth
surface. With these features, the chain is highly wear
resistant and exposes optimal emergency operation
properties.
TGI roller chains
1 Pins made of special alloyed steel,
cold-extruded, case-hardened
(pins starting from 1" are made of
high-alloy heat-treated steel
quenched and tempered), chrome-
plated with high surface hardness
and particularly smooth grinding
2 Bush – seamless, cold-extruded
bush, case-hardened
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, the
plate shape is wide waisted
All components are coated with
Geomet®.
