Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission.

Gervi is a leading manufacturer of a wide range of industrial use power transmission components and equipment.
Differentiating quality, technology development and production systems rather than just simply pursuing cost reductions we believe is a primary goal for Gervi. By forward thinking investment, a fine example being the construction of probably the world’s largest state of the art roller chain manufacturing plant ever by Gervi.

More knowledges for Gervi:

From its advanced production facility in Letchworth, Hertfordshire, Gervi Chain manufactures leaf chain, anchor bolts, pins and pulleys for the materials handling industry, often according to clients’ individual requirements. Gervi Chain is well-known for providing exceptional quality and service and aims to work closely with clients’ design, engineering, procurement and scheduling departments to provide solutions for all their leaf chain needs. Gervi Chain also frequently supplies entire package solutions for OEM build programmes.

As the only leaf chain manufacturer represented by the BITA (British Industrial Truck Association) and the FLTA (Forklift Truck Association), Gervi Chain is also a key source of technical information and application assistance for both equipment manufacturers and operators. Gervi Chain representatives are regularly in attendance at the esteemed BSI Technical Policy Committee meetings and ensure that the company is always at the forefront of the latest chain manufacturing standards, improving the quality and safety of products and procedures for all. Gervi Chain holds ISO 9001:2000 for the manufacture of chain and associated machined products.

As each Gervi  subsidiary focuses on a particular niche product, the group as a whole is able to offer customers highly specialised chain and associated parts for a wide range of different industries and applications. Customers are able to order their required chain (including leaf chain, conveyor chain, roller chain, sawmill or sharp top chain) from their local Gervi branch which will then be shipped from the factory where it is produced.

Roller chain (ISO & ANSI) is known for its high strength and persistent fatigue durability. The sizes fully compliy with ANSI standard. It can be assembled into single-row, double and many rows applying to the transmission power and different configuration space.
According to different working environments, there are different chains with galvanization, nickel plating, chromium plating and Dacroment treatment for you to choose. All surface treatment modes do not contain hexavalent chromium.
based on the transmission roller chains, various attachments like types A, SA, K, SK, and D can be installed according to different functions, forming the most widely used chain products in the field of materials transportation which are appropriate for diversified demands of different industries.
The experimental data show that abrasion of chains is related to the selected lubricating oil. Hengjiu can provide oil film for surface rust protection when the roller chain leaves factory, which can lubricate and reduce friction for a long time; meanwhile, its quality meets EU REACH specification and is more environment friendly.
