BERCO HEAVY DUTY TRACK CHAINS

FOR D4-D7 CLASS MACHINES

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. D5 and

D6 heavy duty chains are also available in the version

with Extreme Wear Resistance Bushings for

maximum life in high abrasion environment.

GREASED TRACK CHAINS

FOR EXCAVATORS AND HEAVY DUTY

APPLICATIONS

A completely new sealing system, consisting of a

W shape polyurethane seal, especially designed to

keep grease in joints and abrasive particles out of them

• Internal pin & bushing wear reduction, with consequent

life extension for 20% and more if compared with the

standard sealed chains on the same application

• Reduction of sneaky tracks phenomenon, as result

of more laterally stable chains, thus reducing wear of

related parts, such as links, rollers, guides

• Improved rebuildability of the track chain

• Noise and maintenance costs reduction and less

machine fuel consumption: improved travelling

performances

FORGED IDLERS

• Hot forged idlers for 15-40 ton class excavators and
for D6R class dozers
• Hot forging gives optimum
internal grain flow and
stronger core
resistance
• Induction hardened
rail surface for
excellent resistance
to wear and fatigue
• Heavier components for
improved stability
• No “drum effect”
noise resonance

FORGED SPROCKETS

• Hot forged sprockets for 10-40 ton class excavators
and for D3-D4 class dozers
• Nine chain pitch versions from 159.8 to 228.6 mm
(6.29”-9”)
• Hot forging gives optimum internal grain flow and
stronger core resistance
• Single shot induction hardened on entire tooth
profile or with differential quenching for excellent
resistance to wear and fatigue
