Roller Chain Links

Roller chain links are the individual components that make up a roller chain, available in both European (BS/ISO) and American (ANSI) standards across a range of pitch sizes. The two base components are roller links, which carry the free-rotating rollers between inner plates, and pin links, which join those roller links together through riveted outer plates. Our roller chain range covers simplex, duplex and triplex configurations in carbon steel and stainless steel, with chain types spanning 05B-1 through 24B-2 and ANSI 40 through 120.

RS offers roller chain links from brands such as Renold, Sedis, Tsubaki, TYC and Witra in New Zealand. They are available as single units or in packs of five or ten, making them suitable for individual repairs or maintenance stock.

Types of Roller Chain Links

RS offers different roller chain links for joining and adjusting roller chains. The main types include connecting pin links and offset pin links.

Connecting Pin Links

Connecting pin links, also referred to as a chain joining link or chain joiner link, are used to join two ends of a roller chain together. These connecting pin links consist of an outer plate fitted with two pins that slot inside the adjacent roller link bushes, and a connecting plate which is fitted separately. They are available in three types:

• Spring Clip Type: The connecting plate is secured using a clip that slides across the end and slots into grooves cut into the end of the pin. This is the most frequently specified chain joining link format across the Renold, Tsubaki and Sedis ranges at RS NZ.
• Cotter/Split Pin Type: The connecting plate is secured by inserting a cotter pin (or split pin) through the end of each connecting pin. Along with the spring clip type, this method provides a clearance fit, where a clearance is always formed between the pin and the hole when assembled.
• Press-Fit Type: The connecting plate is press-fitted onto the pins and secured by a cotter pin or split pin. This is the standard connecting link for ANSI series detachable chains and can also be used on riveted chains in high-speed or demanding applications. This method provides an interference fit, where friction occurs when the pin is inserted into the hole.

Offset Pin Link

An offset pin link combines a roller link and a pin link, consisting of two offset plates, a bush and a movable pin held in place by a cotter pin or split pin. These links are used when the chain length is an odd number of pitches, increasing or decreasing chain length by one pitch, though this practice is not recommended. A two-pitch offset link, also listed as a double offset link, comprises one offset and one roller link and is available across the Tsubaki, Renold and Witra ranges.

Industrial Applications of Roller Chain Links

Roller chain links are used for repairing, maintaining and adjusting roller chains in a range of industrial applications. RS lists roller chains for areas including industrial machinery, conveyors, mining, food and automotive applications.

Drive Chain Repair

Connecting links can be used to join sections of the drive chain during repairs or replacement. The link should match the chain type and pitch for a proper fit. RS offers connecting and other roller chain links in different sizes and specifications.

Conveyor Chain Maintenance

Roller chain links can be used to maintain conveyor systems and replace chain components. They are suitable for industrial conveyor applications where roller chains are used to transmit mechanical power.

Chain Shortening and Lengthening

Offset links can be used to adjust the length of a roller chain by one pitch. They are available alongside connecting links and other chain components for different roller chain types.

Industrial Power Transmission

Roller chain links are part of roller chain systems that transmit mechanical power between rotating components. These systems are used across industrial machinery, conveyors, mining, food processing, automotive and other applications. RS offers links in different chain types, pitches and materials to suit various requirements.
