Designed and manufactured for longer life and lowest cost. Berco's through hardening or differential quenching process increase wear life, provide superior structural support and resistance to deformation.

• Maintenance free for longer life and perfect operation under any working condition
• Large bearing and bushing area for high resistance to radial loads
• Differential quenching or through hardening heat treatment of the roller shell
• Optimal core and internal shell surface hardness for extreme resistance to shock and fatigue stresses by the most severe applications
• Induction hardening and super finishing of the shafts
• Sizeable oil capacity and perfect sealing
