Engineering class chain is typically large in pitch, greater than two inches, and is designed with higher safety factors and more clearances. There are standard sizes, but most are custom designed for special applications. They are rated by working load and ultimate strength. When designing or selecting engineering chain, the load on the chain tension, environment, and service factors are important considerations.
Types of Engineering Chain
Constructed with abrasion resistant pins, bushings, sidebars, and a small roller that improves interaction with the sprocket. Applications are usually high speed with short distances between sprockets. Pitch ranges from 1.654 to 7.50 in. Working load ranges from 2,485 to 37,000 lbs.
Roller Conveyor Chain
Rollers are used to convey products and are designed with attachments to connect the carrying device (plate, pan, cradle, paddle) to the chain. Pitch ranges from 1.654 to 24 in. Working load ranges from 2,100 to 22,300 lbs.
Very similar to conveyor chains except they don’t have rollers. Pitch ranges from 2.609 to 7 in. Working load ranges from 2,500 to 25,000 lbs.
Have bushings that are welded onto the sidebars and they don’t have rollers. They are often used as conveyor chains and sometimes as drive chains. Pitch ranges from 2.609 to 9 in. Working load ranges from 3,500 to 27,600 lbs.
Bar and Pin Chains
Don’t have rollers and bushings. Designed for lifting, pulling, or dragging product and are commonly used for high tension applications, draw benches, lifting devices, dam gates, or in-floor conveyors. Pitch ranges from 2.125 to 18 in. Working load ranges from 4,000 to 30,000 lbs.
Don’t have rollers and bushings. They are sometimes called drop forged rivetless chains and are designed for economy and high-strength with extra lateral flexibility for flexing around corners. A common application is a conveyor trolley system. Pitch ranges from 3.014 to 9.031 in. Working load ranges from 2,000 to 10,800 lbs.
Detachable Link Chain
Don’t have pins, bushings, or rollers. The links are cast, forged, or molded and connected together to form a chain. Links can be detached and replaced. They lack precision and are often found on old agricultural equipment.
Plastic Engineering Chain
Used where tension is low and corrosion is high. Availability is limited. They are typically used for underwater conveyors or chemical applications.
