TRACK CHAINS

 

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.
