Heavy Duty Roller Chain

The Heavy Duty Roller Chain Transmission is a high performance power transmission solution for a variety of applications. It is ideal for machinery that requires a heavy-duty drivetrain, such as skid steers, excavators, and other construction and agricultural equipment. We have the widest selection of heavy duty roller chains with single, double and triple chains in standard stock. In addition, if you don’t see what you need, custom heavy duty roller chains can be manufactured upon request.

Heavy duty roller chains are manufactured to ANSI B29.1 standards, but have thicker side plates. The thicker side plates not only significantly increase the strength and fatigue resistance of the roller chain, but also reduce the stretch and wear that occurs over time. Heavy-duty series roller chains are best suited for agricultural applications, skid steer loaders, heavy equipment, and any application where you want to increase the strength of your chain without increasing its size. We have the widest selection of heavy duty roller chains with single, double and triple chains in standard stock. In addition, custom heavy duty roller chains can be manufactured upon request.

Heavy Duty Roller Chain Specifications

Heavy duty chains are designed for tougher applications, including high-load environments and impact-filled conditions. These chains are suited to industrial and agricultural applications, such as construction equipment, oil rigs, and heavy-duty lumbar equipment.

Some of the components of a roller chain include a sprocket, an idler sprocket, a ring sprocket, and a bushing. Each part is attached to the other through bushings and sleeves. Bushings are used to ensure a smooth bearing surface.

Proper lubrication and assembly are also vital to the life of the chain. Using an improper lubricant can lead to premature wear.

Heavy Duty Roller Chain Applications

Heavy duty roller chains are used in a wide variety of industries. From agricultural machinery to automobiles, roller chains are used to transmit power and move mechanical parts. The use of heavy duty chains can significantly increase the load capacity of a machine.

Heavy duty chains use thicker plates and solid rollers to handle heavier loads. This allows these chains to operate under a variety of harsh conditions. The heat treatment process provides additional protection against wear and shock loads.

Sprockets for Heavy Duty Roller Chain

In addition to heavy duty roller chains, we can also supply sprockets. For heavy-duty roller chains with sprockets with less than 30 teeth, it is recommended that the sprocket teeth be hardened. All our sprockets with up to 30 teeth are supplied with hardened teeth as standard.

Sprockets are available in a wide range of materials, from steel to stainless steel. Typically, they are fabricated from high-quality steel alloys. If you need special sprockets, you may want to consider custom manufacturing.

When selecting a sprocket, you should ensure that it matches the type of chain you intend to use. You should also be aware of how much slack is in the chain. This is important for safe measurement. We are a professional sprocket manufacturer that you can rely on. We also offer a wide range of sprockets. Contact us for more info!
