Double Strand Roller Chains

The use of double strand roller chains means higher tensile strength and working load, these chains are also commonly referred to as duplex roller chains. These chains can be used in a variety of drive and conveyor applications, and all of our simplex and duplex roller chains are also available in corrosion resistant and accessory roller chain configurations.

Choosing Sprockets for Double Strand ANSI Roller Chain

A sprocket is a wheel with teeth. It can be made of various materials, including metals. These wheels are used to provide controlled rotational movement of larger equipment. Typically, they are secured to the shaft with a set screw. They may be produced with removable or fixed teeth.

There are different types of sprockets, which are designed to meet different requirements. They may have narrow or wide teeth, as well as an integral or non-integral shaft.

Double strand roller chain sprockets you choose depends on several factors, including the chain type and the transmission input. If you are running a heavy load, you might want a bushed sprocket. For applications with a higher horsepower, you might want to consider a double or triple strand drive.

Roller chain sprockets are used in many industries. They are often subject to temperature extremes, harsh washdowns, and corrosive environments. Depending on the application, they might be made of plastic or steel. Many sprocket manufacturers will offer a variety of options.

The type of sprockets available also depend on the chain pitch. Pitch diameter refers to the distance between the roller-pin center and the adjacent roller-pin center. Generally, it is measured in 1/8" increments. This measurement is necessary to determine whether the sprocket is a good fit for the chain.

When choosing a sprocket, you need to find a manufacturer that will provide you with information on the interchangeability of the parts. This will help you find the right replacement for your chain. We are exactly the manufacturer that you can rely on.

Double Strand Roller Chain Sprockets

Duplex Roller Chain Manufacturer

The advantage of a double strand roller chain is a high strength chain with a relatively small form factor. The purpose of the chain is to transfer energy to the highest possible efficiency. Our roller chains not only have high energy transfer capability, but also outstanding quality and strength. We stock standard carbon steel, stainless steel, nickel plated, coated and special double roller chains. We also stock sprockets, chain tools and double chain wear guides.

All of our double strand roller chains are fully compliant with the ANSI B29.1 standard. This means they are directly interchangeable with other brands, run on the same sprockets, and use the same attachments. So when you shop with us, you never have to worry about interchangeability, ill-fitting or wear and tear as long as you are using other ANSI standard products. We are also a one-stop store for basically anything you need from electrical components to conveyor and drive components. We also offer custom parts and components wholesale.
