Triple Strand Roller Chain

A triple-strand roller chain, also known as a triplex roller chain, features three parallel strands of chain links, offering even higher tensile strength and working load capacities compared to single and double-strand chains. Triplex roller chains are commonly used in industrial machinery, conveyors, and other high-stress environments.

Hollow Pin Roller Chain

Hollow pin roller chains have a unique link pin design that sets them apart from standard roller chains. Despite this difference, the construction of hollow pin chains is quite similar to that of ANSI standard roller chains. Both types of chains consist of pins, bushings, and small rollers. This similarity in construction allows hollow pin roller chains to be mostly compatible with the sprockets used for the corresponding standard chains.

Heavy Duty Roller Chain

A heavy-duty roller chain is a type of roller chain designed for high-stress applications where increased strength and durability are crucial. These chains feature thicker side plates compared to standard roller chains, which enhances their strength and fatigue resistance. This construction minimizes stretching and wear over time, making them ideal for demanding applications such as agricultural machinery, construction equipment, and industrial machinery.

Heavy-duty roller chains are available in various configurations, including single-strand (simplex), double-strand (duplex), and triple-strand (triplex) versions, each providing varying levels of strength and capacity. They are manufactured to ANSI standards, ensuring compatibility and reliability across different uses. Additionally, these chains can be produced in riveted or cottered styles, offering flexibility depending on the specific needs of the application.

Cottered Roller Chain

A cottered roller chain is a type of roller chain that uses cotter pins to secure the chain links. Unlike riveted roller chains, cottered chains allow for easier disassembly and maintenance since the cotter pins can be removed without the need for grinding off the pin heads. This design is particularly beneficial in applications where frequent chain adjustments or replacements are necessary. Cottered roller chains are commonly used in heavy-duty industrial applications, including conveyors, agricultural machinery, and mining equipment, due to their durability and ease of maintenance. These chains conform to ANSI standards and are typically made from high-quality carbon steel that is heat-treated for enhanced strength and wear resistance.

Metric Roller Chain

Single Strand Roller Chain

A metric single-strand roller chain, also known as a simplex ISO chain, is a roller chain manufactured to ISO British standards. The key dimensions of a metric single-strand roller chain include the pitch (the distance between roller centers), roller diameter, and inner width. These chains are available in various strength grades and materials to suit different load capacities and environmental conditions.
