ROLLERS

 

Designed and manufactured for longer life and lo west cost. Berco’s through hardening or differential quenching processes increase wear life, provide superior structural support and resistance to deformation. Berco’s exclusive seal groups help ensure lifetime lubrication for extended life and to reduce your cost.

  • Single flange, double flange and inner flange rollers.

  • Ultra low temperature (-50°) version available).

  • More than 1.500 different rollers, to match any chain or application.

  • For track-type machines ranging from 1 to 300 ton.

  • Hot forget in two halves to obtain best internal grain flow.

  • Specific low alloyed boron steel for high hardenability.

  • Differential quenching or trough hardening heat treatment of the rollers shell guarantees a rail surface with a superior wear resistance (HRC>50); optimum core and internal shell surface hardness for extreme resistance to shock and fatigue stresses caused by the most severe applications.

  • Introduction hardening and super finishing of the shaft.

  • Large bearing and bushing area for high resistance to radial loads.

  • Sizeable oil capacity and perfect sealing.

  • Maintenance free, for longer life and perfect operation under any working condition.

  • Precise design and carefully manufactured for perfect alignment, perfect fit of bushing and final assembly of the components.
