NERAK Rubber Block Chains are the heart of every NERAK conveyor.

Rubber is molded around pre-stressed high tensile steel cables in a high pressure vulcanizing process. Chemical bonding between these steel cables and the specially mixed raw rubber compound ensures exceptional durability, strength and longevity.

NERAK offers a variety of different chains for a diverse range of applications and a large number of materials to be conveyed.


NERAK Rubber Block Chains are manufactured in different sizes and rubber compounds to supply the right Rubber Block Chain for the application.

Abrasion Resistant

Rubber Block Chains withstand the most abrasive products, unlike metal and plastic chains. The elastic surface of the chains allow the impact of abrasive materials to be absorbed without wear.
