Introduction

UHMW-PE is defined as polyethylene whose molecular weight is 3.1 million or higher. When making this determination, it was found that physical properties increased rapidly as lower CHINAMFG values increased, and then leveled off at the 3,100,000 value. As with most high-performance polymers, the processing of UHMW-PE is not easy. Because of its high melt viscosity, conventional molding and extrusion processes would break the long molecular chains that give the material its excellent properties. Current manufacturing methods include compression molding, ram extrusion and the warm forging of extruded slugs. UHMW-PE has the outstanding abrasion resistance and an extremely low coefficient of friction. Impact strength is high and chemical resistance is excellent.

The material does not break in impact strength tests using standard notched specimens; double-notched specimens break at 20 ft-lb/in (42.1 kJ/m2). UHMW-PE has a crystalline melting point of 267°F (131°C). The recommended maximum service is about 200°F (93°C).
 Care should be taken when fastening UHMW-PE, as its large thermal expansion can cause the material to buckle between fasteners if they are too far apart.
UHMW (ultra-high molecular weight polyethylene) is an extremely tough plastic with high abrasion and wear resistance.
The versatility of polyethylene has made it a popular plastic for countless industrial applications that require durability, low friction, and chemical resistance.


These wear strips are mounted on the tracks over which the chain travels. Special Antistatic grade of Ultra High Molecular Weight Polyethylene (UHMWPE having antistatic property ensures its suitability for LPG installations, reducing chances of sparks / static current developed because of friction. Various Rectangular, Square, Trapezoidal cross sections, “C” Profile , Special shapes, Curves etc. are available suitable for all installations. Installation of these liners ensures prolonged working of dry chains in dusty atmosphere.

engineering chain

Can engineering chains be used in agricultural machinery and equipment?

Yes, engineering chains are commonly used in various agricultural machinery and equipment applications. Their robust design and ability to handle heavy loads make them well-suited for the demanding and often harsh conditions in the agricultural industry. Here are some examples of how engineering chains are used in agriculture:

  • Combine Harvesters: Engineering chains are utilized in combine harvesters to drive components like the cutter head, reel, and auger. These chains are essential for efficient harvesting and grain collection.
  • Tractors: In tractors, engineering chains are employed in power take-off (PTO) systems to transfer power from the engine to different agricultural implements, such as plows, mowers, and tillers.
  • Balers: Engineering chains are used in balers to compress and bind crops into bales, facilitating easy storage and transport.
  • Seeders and Planters: These machines use engineering chains to distribute seeds or plants evenly in the field, ensuring proper crop spacing and optimal growth.
  • Grain Handling Equipment: Engineering chains are integral in grain handling equipment, including bucket elevators, grain conveyors, and grain elevators, facilitating the efficient movement and storage of harvested crops.

The agricultural environment can be challenging, with factors such as dust, debris, and varying weather conditions. Engineering chains used in agricultural machinery are often designed with additional protection against contaminants and corrosion to ensure reliable performance over extended periods.

When selecting engineering chains for agricultural applications, it’s essential to consider factors like load capacity, environmental conditions, maintenance requirements, and the specific needs of each machine. Regular inspection and proper lubrication are crucial to maintain the chains’ performance and extend their service life in agricultural machinery.

How do engineering chains handle angular misalignment between sprockets?

Engineering chains are designed to handle a certain degree of angular misalignment between sprockets. Angular misalignment occurs when the rotational axes of the driving and driven sprockets are not perfectly parallel, leading to an angle between them. While it is essential to minimize misalignment to prevent excessive wear and premature failure, some level of misalignment tolerance is built into engineering chains to accommodate real-world installation variations.

When angular misalignment exists, the chain’s side plates and rollers are designed to articulate and adjust to the varying angles between the sprockets. This flexibility allows the chain to smoothly engage and disengage from the sprocket teeth without binding or jamming. However, it’s important to note that excessive misalignment can still cause accelerated wear, noise, and reduced efficiency in the chain drive system.

To ensure optimal performance and longevity, it is recommended to keep angular misalignment within the manufacturer’s specified limits. These limits can vary depending on the chain size, type, and application. When installing an engineering chain, it’s crucial to align the sprockets as accurately as possible and use alignment tools if necessary.

In applications where angular misalignment is unavoidable, special chain types or accessories, such as chain tensioners or idler sprockets, can be used to help compensate for the misalignment and improve overall system performance.

In summary, engineering chains are designed to handle a certain degree of angular misalignment between sprockets, but it is essential to follow the manufacturer’s guidelines and maintain proper alignment to ensure reliable and efficient operation of the chain drive system.

How does an engineering chain differ from a standard roller chain?

Engineering chains and standard roller chains share similarities in terms of their basic design, consisting of interconnected links that engage with sprockets for power transmission. However, there are key differences between the two types of chains:

  • Application: Standard roller chains, also known as transmission chains, are primarily used for power transmission in industrial applications. They are commonly found in machinery, automotive, and other power transmission systems. On the other hand, engineering chains have a broader range of applications and are specifically designed for various industrial uses beyond pure power transmission.
  • Design and Construction: Engineering chains are available in different configurations and materials to meet specific industrial needs. They come in various types like drag chains, apron chains, leaf chains, and more, each tailored for a particular application, such as material handling, lifting, or conveying. Standard roller chains have a more standardized design with cylindrical rollers, providing smooth motion in power transmission applications.
  • Attachments: Engineering chains often feature attachments or extended pins that allow for the connection of specialized components or accessories. These attachments can be used for carrying loads, attaching products, or facilitating specific tasks in industrial processes. Standard roller chains, on the other hand, typically do not come with attachments.
  • Load Capacity: Engineering chains are designed to handle a wide range of loads, including heavy loads, abrasive materials, and harsh environmental conditions. They are built to withstand the demands of rugged industrial settings. Standard roller chains are suitable for general power transmission applications and may not be as robust as engineering chains in challenging environments.
  • Specialty Chains: Engineering chains include various specialty chains that cater to specific industries and applications, such as mining, agriculture, escalators, and more. Standard roller chains do not have the same diversity of specialized variants.

In summary, engineering chains are more versatile and adaptable, tailored to a broader range of industrial applications beyond power transmission. They offer a wider variety of designs, materials, and attachments to suit specific needs, making them suitable for demanding and specialized tasks in various industries.
