Why Berco is Your Best Undercarriage Value
Berco Rollers are designed and manufactured for longer life. Berco’s through hardening or differential quenching processes increases wear life, provide superior structural support and resistance to deformation. Berco’s exclusive seal groups leverage sizeable oil capacity and perfect sealing to provide a maintenance free, longer lasting roller helping to reduce your costs.
The Process and Materials
• Berco rollers are hot forged in two halves to obtain best internal grain flow.
• Specific low alloyed boron steel is used to achieve high harden-ability.
• Differential quenching or through hardening heat treatment of the roller 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
• Induction hardening and super finishing of the shafts
• Large bearing and bushing area for high resistance to radial loads
• Precise design and carefully manufactured for perfect alignment, perfect fit of bushings and final assembly of the components
