Roller Chain Links & Accessories
Premium Roller Chain Links for Industrial Power Transmission
Machinery Sprocket supplies a complete range of high-quality roller chain links and accessories designed for strength, precision, and reliability. We stock three primary types of roller chain links — connecting links (master links), roller links (inside links), and offset links (half links) — all manufactured to ANSI, ISO, and DIN standards. Each link is engineered from heat-treated alloy steel to provide outstanding tensile strength, wear resistance, and long service life, ensuring consistent performance in any power transmission system.
Connecting Links (Master Links) for Easy Installation
Our connecting links, also known as master links, allow quick and secure chain assembly or removal without complex tools. They are precision-machined to ensure proper alignment and reliable engagement with the roller chain, maintaining smooth operation under load. Available in spring clip, cotter pin, or riveted types, these links are ideal for both light-duty and heavy-duty machinery applications, offering flexibility and durability that maintenance engineers depend on.
Roller Links (Inside Links) for Chain Maintenance
Roller links, sometimes referred to as inside links, are used to replace worn or damaged chain sections to restore full performance. Manufactured with precision rollers and bushings, our inside links match the exact specifications of standard roller chains. The consistent material hardness and smooth roller finish minimize friction and reduce elongation, helping users maximize chain longevity and efficiency in conveyors, agricultural machines, and factory automation systems.
Offset Links (Half Links) for Accurate Length Adjustment
Offset links, or half links, are specifically designed for fine chain length adjustment when an odd number of pitches is required. Built to maintain correct alignment and tension, our offset links ensure accurate sprocket engagement and smooth chain motion. Each piece undergoes strict inspection for hardness, dimensional precision, and surface finish, making it a dependable choice for equipment installers and repair technicians seeking flexibility in limited-space applications.
Roller Chain Repair and Maintenance Kits
To make maintenance easier and faster, we provide complete roller chain repair kits and maintenance kits. Each kit includes connecting links, pins, plates, and rollers, all matched to fit specific chain sizes. Our maintenance kits also contain cleaning and lubrication tools to simplify preventive care. With these kits, users can perform on-site repairs, reduce equipment downtime, and extend the operational life of their roller chains — an essential resource for workshops, distributors, and OEM factories.
Excellence in Quality and Service
We has built its reputation on delivering quality products backed by reliable service. Our in-house inspection and sealing teams work tirelessly to ensure every link meets the highest performance standards. Each roller chain component is tested for hardness, tensile strength, fatigue resistance, and precise fit before shipment. This commitment to quality manufacturing ensures stable, long-term performance even under heavy loads or high-speed conditions.

Frequently Asked Question
A drive chain is a mechanical device used to transmit power from one point to another, commonly found in motorcycles, bicycles, and industrial machinery. It consists of links, rollers, pins, and sprockets that work together to transfer motion efficiently.
Drive chains transfer motion through a continuous loop of interlinked components. As the sprockets rotate, they engage with the chain’s links, transmitting power to move wheels or other machinery parts. The smooth operation of rollers reduces friction for efficient power transfer.
You should replace your drive chain when it shows signs of significant wear such as elongation, stiff links, or excessive noise. Regular maintenance and inspections can help extend its lifespan, but replace it when wear becomes noticeable.
The lifespan of a drive chain depends on usage and maintenance. A well-maintained chain can last between 15,000 to 20,000 miles in automotive applications and several years in industrial settings. Proper lubrication and tensioning can greatly extend its life.
Drive chains are cost-effective, durable, easy to maintain, and offer efficient power transmission. They are capable of handling high loads and high speeds, making them ideal for both light and heavy-duty applications.
A roller chain is a specific type of drive chain that features rollers between the links to reduce friction. While all roller chains are drive chains, not all drive chains are roller chains. Other types of drive chains, like silent chains, may use different mechanisms for power transmission.
