Product Description

 

81X chain features a 2.609″ pitch and is categorized as a steel bushed roller chain within the engineer class of chains. Its
commonly referred to as an 81X conveyor chain due to the straight side-bar design and common usage within conveying applications. Most commonly, this chain is found in the lumber and forestry industry and is available with upgrades such as “chrome pins” or heavier-duty side-bars. Our high-strength chain is manufactured to ANSI specifications and dimensionally interchanges with other brands, meaning sprocket replacement is not necessary. We also supply 81X sprockets, attachments, and we have a Made in USA 81X chain breaker. Because of its high-strength and effective design.

 

This chain is found in a wide range of applications including; asphalt paving, car wash, citrus processing, clean grain and return elevators, fertilizer conveying, food processing, forest products, grain handling, manure spreaders, produce wash-down and many more!

 

 

 

Design and Processing Advantages
1. Made of medium carbon steel, the offset sidebar roller chain undergoes processing steps like heating, bending, as well as cold pressing after annealing.
2. The pin hole is created by impact extrusion, which increases the inner surface smoothness for the hole. Thus, the matching area between the sidebar and the pin is increased, and the pins offer higher protection against heavy loads.
3. The integral heat treatment for the chain plates and rollers ensures high tensile strength. The pins additionally undergo
high-frequency induction heating for the surface after integral heat treatment, ensuring high strength, high surface hardness, and wearing resistance as well. The surface carburizing treatment for the bushings or sleeves guarantees high tensile strength, superb surface hardness, and improved impact resistance. These make sure the heavy duty transmission chain has extended service life.

Our range of 81X chain and 81X sprockets covers the most popular styles available worldwide. It is a 2.609 pitch, straight sidebar chain, and ready for immediate delivery to your site.

81X chains are commonly found in the timber industry and used for conveyors, stackers, sorters, trimmer saws, and un-scramblers. Due to their low-cost these chains are found in a wide variety of applications & industries.

The styles of 81X chain that we stock are manufactured from different materials, plate thickness and sidebar heights. This selection enables you to have higher working loads and extend your chains service life.

Our range of 81X chains and sprockets in CHINAMFG are available in different tiers of quality and price. All chains come with CHINAMFG bush and roller, with fully heat-treated components and are manufactured to commercial standards for clearance, fits and limits.

We stock 81X chain in 10-foot rolls and stock a full range of rivets, connector links, attachments, and sprockets.

Can heavy-duty chains be used in automotive and transportation equipment?

Yes, heavy-duty chains can be used in various automotive and transportation equipment applications. These chains are designed to handle heavy loads and provide reliable power transmission in demanding conditions, making them suitable for a wide range of automotive and transportation-related tasks.

In automotive applications, heavy-duty chains can be found in timing systems, where they ensure precise synchronization between the engine’s camshaft and crankshaft. They are also used in transfer cases, differentials, and other drivetrain components that require robust and dependable power transmission.

Transportation equipment, such as trucks, buses, and industrial vehicles, often rely on heavy-duty chains for various functions, including suspension systems, lifting mechanisms, and steering systems. In these applications, the chains must withstand continuous use and exposure to environmental factors.

Heavy-duty chains are engineered to offer exceptional durability, high tensile strength, and resistance to wear, making them a reliable choice for automotive and transportation equipment that operates under heavy loads and challenging conditions.

What are the temperature limits for heavy-duty chains in extreme environments?

Heavy-duty chains are designed to perform well in a wide range of temperatures, but their temperature limits in extreme environments depend on the materials they are made from and the specific application.

Generally, heavy-duty chains can handle temperatures ranging from -20°C to 200°C (-4°F to 392°F) in standard operating conditions. However, in extreme environments, such as foundries, steel mills, or extremely cold regions, special high-temperature or low-temperature chains may be required.

For high-temperature applications, heavy-duty chains made from heat-resistant materials, such as alloy steels or stainless steels, can withstand temperatures above 200°C (392°F) without losing their structural integrity.

On the other hand, in extremely cold environments, heavy-duty chains made from low-temperature materials, like specific grades of carbon steel or nickel-plated chains, can maintain their strength and flexibility at temperatures as low as -40°C (-40°F) and even lower.

When operating heavy-duty chains in extreme environments, it is essential to consider factors such as thermal expansion, contraction, and possible lubrication challenges. Adequate lubrication is crucial to ensure smooth operation and to protect the chains from wear and corrosion caused by temperature variations.

In critical applications with extreme temperature conditions, consulting with chain manufacturers or industry experts can help determine the most suitable heavy-duty chain materials and configurations for the specific environment to ensure optimal performance and longevity.

Can heavy-duty chains be used in outdoor or harsh environments?

Yes, heavy-duty chains are specifically designed to excel in outdoor or harsh environments. Their robust construction and choice of high-strength materials make them well-suited for demanding applications where exposure to extreme weather, moisture, and other challenging conditions is common. Some of the environments where heavy-duty chains are commonly used include:

  • Construction Sites: Heavy-duty chains are extensively used in construction equipment like excavators, bulldozers, and cranes, where they must withstand the rigors of construction sites.
  • Mining Operations: In mining equipment such as loaders, haul trucks, and crushers, heavy-duty chains play a critical role in handling heavy loads and operating in harsh conditions.
  • Marine Environments: Stainless steel and galvanized heavy-duty chains are utilized in marine equipment due to their corrosion resistance, making them ideal for ship mooring, lifting, and anchoring.
  • Agricultural Settings: Heavy-duty chains are commonly employed in agricultural machinery for various tasks like tilling, harvesting, and irrigation.
  • Forestry Applications: In forestry equipment, such as logging machinery and sawmills, heavy-duty chains are essential to handle the demanding conditions of wood processing.
  • Outdoor Power Equipment: Chainsaws and other outdoor power tools often use heavy-duty chains to endure the stresses of cutting through tough materials.

These chains are designed to resist corrosion, abrasion, and fatigue, ensuring their reliable performance in challenging outdoor environments. Regular maintenance and proper lubrication are still necessary to prolong the lifespan and efficiency of heavy-duty chains when used in such conditions.
