Continuous research in steel metallurgy together with computerized
management of all working parameters ensure Berco links attain the finest
possible quality standards and place them among the best products
available for this particular market. Berco links excellent wear
resistance, even in the most severe working conditions, is assured by
modern rail induction hardening systems as well as accurate control
systems, complying with ISO9001 International Standards. Berco links have
a running rail surface hardness of Rockwell C 55, a case depth hardness of
Rockwell C 45 (from 5 to 13 mm depending on size) and a core hardness of
Rockwell C 30.
HEAVY
DUTY TRACK CHAINS
Heavy
duty, sealed & lubricated track chains have been specifically designed for
increased pin & bushing retention. Track link incorporates greater
pin-to-link and bushing-to-link contact areas while additional link wear
material increases component life. Heavy duty chains are also available in
the version with Extreme Wear Resistance Bushings for maximum life in high
abrasion environment. Exclusive heat treatment gives Berco links
consistent surface hardness, superior hardened depth and strong core
hardness. Berco pins & bushings are dimensionally matched to the links and
manufactured to provide excellent track joint reliability, while the
design ensures maximum sealability. All this results in excellent wear
resistance, strength and durability for superior sealability and longer
life. Heavy duty track chains work best in moderate to high impact
conditions, logging, reforestation, side sloping and for uneven terrain.
Heavy duty track chains with Extreme Wear Resistance Bushings, work best
in high abrasion/low impact application.
Heavy
Duty Chains version with Extreme Wear Resistance Bushings available as
an option.
For
track-type machines ranging in class from D4H-HD to D7H-HD.
Suitable for XR, XL, LGP and TSK undercarriages.
Ultra
low temperature (-50° C) version available.
Greater
pin-to-link and bushing-to-link contact areas for increased pin
retention.
Higher
track link provide additional wear material.
Track
links are forged from deep hardening low alloyed boron steels with
certified hardenability based on Berco’s specification.
Links
are quenched & tempered for tough and strong core hardness, superior
strength and higher pin & bushing retention.
Rail
surface induction hardened (HRC 53) to the wear limit (HRC>45).
Final
furnace tempering reduces link chipping and spalling.
Bushing
are treated in a special furnace for high temperature carburizing.
Pins
are deep hardened for best resistance to wear and fatigue.
BERCO LUBRICATED TRACK CHAINS
Berco has
produced the lubricated chains after a prolonged test period both at the
factory and in actual working conditions.
The chain
is a technically superior product.
Special
production machines have been developed exclusively by Berco to mass
produce the chain components. Each component is passed through special
cleaning machines which remove foreign material that remain on the parts,
after cleaning parts are assembled on Berco track presses which have been
engineered for accurate assembly. Vacuum testing and the injection of oil
into the lubricated track joints is performed by a machine specially
designed and manufactured by Berco.
The Berco
master split link was designed by Berco engineers and is an important part
of the lubricated chain.
When
using the lubricated chain there is no wear between the pin and bush.
The pitch
extension caused by internal wear on standard chains is eliminated and
results in longer life for all matching components, especially segment and
sprocket teeth.
Bushing
which have an increased thickness and no internal wear last much longer;
the life of pins is for all practical purposes unlimited.
With
Berco lubricated chains the friction normally associated with the chains
is greatly reduced allowing more effective use of the engine power,
quieter operation and improved operative comfort.
