No. 40 Roller Chain Offset Link

This pack contains five offset links sized for No. 40 roller chain. They join chain strands when an odd number of pitches is required for machinery drives. The links suit industrial, agricultural and motorcycle power-transmission systems.

Thermals noise and power draw

Offset links are passive metal components that generate no heat, noise or electrical draw. They transmit mechanical power without adding thermal load to the drive system. Lubrication of the surrounding chain governs operating temperature and sound.

Five-link pack convenience

The five-piece quantity lets technicians complete a repair or keep spares in a maintenance kit. Each link installs with standard chain tools, reducing downtime on conveyors, harvesters or bike drivetrains. No additional hardware or software is bundled.

Questions about this item

How do I install the No. 40 roller chain offset link and what step is often missed?

Press the link plates onto the pins of the adjoining chain ends, then secure the supplied retaining clips fully into the pin grooves; the step often missed is seating both clips completely so they cannot work loose.

What maintenance or replacement will the No. 40 offset link need later?

Inspect the link periodically for pin wear, plate stretch, or missing retaining clips; replace the link if elongation exceeds the chain pitch limit or if any clip is damaged or absent.

What limit appears first on the No. 40 offset link under sustained use?

The link plates and pins wear at the joint, increasing pitch length until the chain no longer meshes cleanly with the sprocket teeth, which is the first functional limit reached.
