BERCO produces idlers and sprockets for all machines for which chains and rollers are manufactured; therefore, the entire undercarriage can be repaired with parts of the same high quality.
The same CAD-CAE design tools (Computer Aided Design - Computer Aided  Engineering) used for other components are also very helpful in the idler shell design. The Finite Element Analysis is applied in order to optimize the critical sections, so front idlers with the highest performances and longest durability are produced.

Berco also manufactures drive sprockets with replaceable segments and
sprocket rims as well.

Front Idlers
These products, depending on size and application, are made according to two main manufacturing concepts; steel casting and fabrication by electric welding process.
Berco's comprehensive experience in both manufacturing techniques ensures the durability and toughness of its front idlers.
Hardness of running rail surfaces is Rockwell C 54, And Rockwell C 40 measured at a depth of 4 to 8 mm depending on size of the section.
Berco's wide range includes idlers with brackets, supplied as fully sealed and lubricated assemblies from the factory, up to complete idler groups (tensioning and adjusting devices included).

Sprockets and Sprocket Rims
These components, made out of cast steel with reinforced geometry at stressed sections, undergo accurate machining and induction hardening process specifically 
tailored to the different sizes. This allows perfect inter changeability and superior wear resistance. In both cases, the teeth are subject to an induction hardening process which gives them a surface hardness of Rockwell C 54, with a case depth of 4 to 8 mm depending on size, at Rockwell C 40.

Segment groups
To simplify service activities, segment groups are offered as replacement parts.
These components, made of selected steel for the through hardening process, are forged using a system which guarantees a favorable fiber flow of the material, making the teeth particularly tough and resistant to breakage.
The above mentioned heat treatment grants the segments a core hardness of Rockwell C 45 and a surface hardness of Rockwell C 50 or higher.
