Conveyor Chains As a comprehensive chain manufacturer, we produce Roller Chains, Conveyor Chains, Cast Chains and many other types of chains. We provide a full range of manufacturing processes from machining through heat treatment for assembly based on our experience and technologies accumulated over more than 100 years. We are proud that our products keep contributing to industrial progresses in Japan and abroad.

Introduction Our conveyor chains, sprockets and other products are widely used in mainstream conveyor systems, to meet customer requests. Their specifications, applications and environments are very diverse. Nevertheless, errors or shortcomings in selection, handling and maintenance can not only impede the flow of material on the conveyor but can cause major accidents, including chain breakage and conveyor damage. This catalog includes information to assist in the correct selection, handling and maintenance of chains and sprockets, so please read it with care before using our products. Key...

Use Please pay particular attention to the following points when using conveyor chains and sprockets. 1. Select the right product. 140P Refer to “Selecting Conveyor Chains” [1] Conveyor chains may break when an excessive load is placed on them. Be sure to use any chain only within its proper load capacity, based on an understanding of its structure and specifications. [2] Use of conveyor chains in alkaline or acidic surroundings can cause brittle fracture, so be sure to select the appropriate chains the conditions in which it will be used. Acid Alkali [3] The performance of conveyor chains...

[2] Do not subject the conveyor chains to direct impact, or to direct heating by blowtorch etc. Such treatment will greatly reduce chain performance and could cause the chain breakage. [3] Re-machining chains and sprockets is dangerous. Never electroplate heat-treated chains or sprockets, as it can cause hydrogen embrittlement fracture. Never weld heat-treated chains or sprockets, as heat effects can reduce strength, causing the chain to break. After using a blowtorch or other heat source to heat or cut a chain, be sure to remove all components on either side of the heated area that may...

List of Conveyor Chains Standard Conveyor Chains These chains are assembled from precisely-fitted links, bushes and pins, each made from carbon steel or hardened steel, to give accurate dimensions. Rollers are available in R, F or S roller types to suit different applications. HB-type Bushed Chains These chains have no rollers, and are used in trolley conveyors and log haul conveyors. Roller Chains with Attachments Conveyor Chains with Attachments Various attachment can be installed depending on the applications. K-type Attachment Double Pitch Roller Chains for Conveyors S roller chains...

These chains are made with special hollow pins, allowing mounting of various types of attachments. They are indicated by the“HP”suffix on the chain number. Side Roller Chains These chains are standard roller chains or double pitch roller chains with side rollers attached to one or both sides, in parallel or staggered patterns. Plastic rollers are used to reduce noise. SAV type Stainless Chains HEP type Plastic Chains We used our wide-ranging expertise from conventional metal chains to develop this specialized chain, made from engineering plastic, for sludge agitation. These chains have...

List of Conveyor Chains Intermediate Carrier Chain These chains offer improved wear resistance. There are 730TAW and S730TAW types for use in water treatment. Steel Block Chains Welded Chains These chains have welded structures, in which the barrels are welded to the link plates. These chains are used for Sugar Industry. We can offer various types of chains with good workmanship. These chains incorporate precisely-machined steel blocks. They are used for carrying heavy items in locations such as steelworks, as well as in applications such as draw benches and sluice gates. Offset type Case...

Detachable Chains Steel Drag Chains These chains have wide bases and are used to carry loose cases and troughs. Drag Chains Pintle Chains The barrel and link are a single casting, and the chain is assembled by inserting carbon steel pins. The increased strength, relative to detachable chains allows a wider range of applications. These chains can be detached easily at any point, and their structures are very easy to handle. They run smoothly, with little rusting, even in corrosive environments. A simple and sturdy structure, making a wide and heavy chain that can carry rough and hard...

Terminology Concerning Chain Strength No. 1． Term Tensile Strength Meaning The maximum load when the chain is pulled to the point of breaking. Tensile Strength (Ultimate Load) Test method As shown in the diagram, both ends of chains are fastened to a clamping device and gradually pulled until it breaks, at which point the maximum tensile strength is measured. Notes 1. Values resulting from failure of the clamping device are not applicable. 2. The clamping device is able to move freely for all links when chain is pulled. Average Tensile Strength The setting value from calculation of tensile...
