Rubber Block Chain

Yonghang original rubber block chain is an important component in Continuous Vertical Conveyor, Reciprocating Lifts or bucket transport systems for bulk material.
Yonghang rubber block chain operates grease free, and therewith clean compared to steel chains.
Rubber block chain made of modified natural rubber operate very quiet and avoid the necessarity to wear ear protection when working nearby.
Rubber block chain are very strong, with steel cables inside and a reliable binding between rubber and steel cables.
Rubber block chain come with a lock for easy installation, or endless vulcanized for better resistance against weather and aggressive pollution influence.
Yonghang uses rubber block chain in own machines for reliable and quiet operation, and also offers the chains as spare parts and replacement in other machines operating with a similar system.

Features include:

Maintenance-free
No corrosion
Silent operation
Wear-resistant
Without hinges

Application

As the core component of vertical lifting equipment, Yonghang rubber block chain is manufactured with several specially processed high-tension wire ropes that are used as the rubber chain skeleton and rubber through high temperature and high pressure fluidizing process.

Application scenario: Yonghang Rubber Chains have achieved reliable high-quality application in continuous elevator, grab elevator, reciprocating elevator, straight cross sorting machine, recirculating fork vertical elevator, etc.

Model (as shown below): Multiple specifications and lengths can be customized based on customer requirements, which can be annular or linked by hinges.

At the heart of all our conveying systems lies the heavy-duty NERAK rubber block chain.
The rubber outer layer is tightly bonded to high-strength flexible steel cables through a high-pressure vulcanization process.
Even under the most demanding operating conditions, such as when used on rubber extrusion cooling lines
where the conveyor belt remains continuously submerged in water, the robust bond between the rubber skeleton and inner steel cables ensures completely corrosion-free operation and an exceptionally long service life. All NERAK rubber block chains are manufactured in our own modern factory, enabling us to guarantee the correct type and style of rubber chain for every application.
