John King USA Inc.

John King manufactures roller and rollerless engineered steel chains and sprockets. Our chains are engineered and constructed to withstand the rigorous operating conditions found in bucket elevator and conveyors in the following industries: Cement & Quarry Mining & Steel Commercial Agriculture Power Generation Wood & Wood Products Water Treatment Pulp & Paper John King’s experience allows us to select the best steel alloys and combine this with superior heat treating capabilities. This enables the company to provide the best chain solutions for conveying at a cost-effective price, while maintaining reliability and productivity.

John King Climax premium cast chains are most commonly used in material handling, sewage treatment, water filtration, fertilizer handling, sugar processing, waste wood conveying, and other applications. They are manufactured to withstand the abuse of industrial applications where cost-effective solutions are of great importance. These chains are assembled with heat-treated pins and slightly larger tolerances. This allows the material to easily work out of the connection points. Furthermore, they are designed and fully tested for dimensional consistency, interchangeability, and correct sprocket engagement. Most standard sizes are available from stock, with MTO and custom designed castings also available.

John King USA High Temperature Alloy drag chains are suitable for use in extreme temperature applications such as Lime Kiln Conveyors, Ash Handling Conveyors, Calcining Systems & Cement Clinker Conveyors. Our chains are supplied with super-hard locked pins, to prevent rotation and unnecessary pin wear, through hardened Cast Alloy or Manganese Alloy Links and optional added Hard Welds to improve overall abrasion life. Sprockets and other accessories are also available from our East Peoria Plant. John King USA can also supply stainless steel heat recovery chains on a fabricated basis.

John King round link steel chains have become a proven standard in aggressive mining, ash handling, cement production, and other heavy-duty applications due to their high strength and flexibility in operation. They are built to meet or exceed the German Institute for Standardization (DIN) for dimensional consistency, interchangeability, and correct sprocket engagement, most commonly with the DIN 22252 & DIN 764 specifications. They are offered in both the standard hardness state (through-hardened) or with upgraded surface hardness (case-hardened) to best combat abrasive wear. We also offer a range of quality accessories such as forged master links, attachment shackles, mounting hardware, and complete sprocket solutions. Most common sizes are available from inventory and can be cut to length quickly and accurately to meet on-demand ordering and emergency repair needs.

John King forged alloy fork link chain provides an excellent solution for the rigors of heavy duty conveying systems such as cement clinker or boiler ash handling. The low carbon, high strength base material used to manufacture these forged chains is strong and ductile to combat shock loads. The surface of the chain is case hardened to RC60 to give excellent abrasion resistance. These chains are kept in stock at our facility in East Peoria, IL. Combine these attributes with the experience that John King has regarding forged chains.

transmission of mechanical power. Our chains are built to ANSI B29.1 standards for dimensional consistency, interchangeability, and correct sprocket engagement. They feature premium solid bushings, ensuring a precision fit between the pin and bushing, therefore providing the longest possible service life. We keep most common sizes on-hand, guaranteeing prompt order fulfillment.

John King Climax British Standard chains are commonly used for conveying applications. They are built to International Standards Organization (ISO) metric dimensions for dimensional consistency, interchangeability, and correct sprocket engagement. They feature additional heat treatment to side plates not found in the competition’s products. This process effectively doubles the ultimate strength and service life when compared to other chains on the market. We keep most common sizes on-hand, guaranteeing prompt order fulfillment.

John King Climax premium combination chains are most commonly used in light-to-medium duty conveying applications where a durable yet cost effective chain is needed. Combination chains are often utilized for stone, gravel, coal and other abrasive materials. They are manufactured with hardened cast block links and heat-treated steel sidebars and pins to withstand the abuse of industrial applications. Our combination chains are designed and fully tested for dimensional consistency, interchangeability, and correct sprocket engagement. Most standard sizes are available from stock, with MTO and custom designed chain and attachments also available.

John King Climax engineering class drive chain is used for power transmission and speed reduction in many heavy duty applications. Our drive chains are designed to exceed the listed ultimate strength ratings, ensuring high fatigue strength and the ability to withstand extreme shock loads. Each component is manufactured entirely from alloy steel, carefully machined with high press fit tolerances. Components are heat-treated with the latest techniques to ensure the longest service life for both the chain and sprockets. We keep most common sizes on-hand, guaranteeing prompt order fulfillment.

John King USA has successfully supplied the bakery industry with conveyor chains, sprockets and components over many years. Our experience covers installations with High Output Bread and Roll Automated production lines using Lanham, Bake-Tech and Stewart oven and Proofer systems. In addition to high speed baking lines, John King USA manufactures conventional engineered steel conveyor chains typically used in pantin bread tunnel ovens. These chains have rigidly controlled pitch to optimize sprocket gearing, low friction and reduction in both wear and noise levels.
