Joints and false links
Joints and False Links for Industrial Chains
Transmission chains are typically supplied with free terminals. To properly connect these terminals, joints are used, available in various types depending on assembly requirements and strength.
Spring clip joints and safety pin joints allow for quick assembly and disassembly, making them ideal for frequent maintenance interventions. In contrast, the rivet joint ensures an extremely robust and permanent connection, but must be made in the factory or with specific equipment.
When the pitch number of an open chain is odd, a filler link must be used. This component consists of two special plates fixed with a pin and a roller; the wider part of the link is mounted at the end of the chain and locked with a safety pin.
It is important to pay particular attention to the use of filler links or spring clip or safety pin joints, as they can significantly reduce the break load of the chain and, consequently, its operational reliability.

Frequently asked questions
What is the difference between a joint and a false link?
The joint and the false link are two accessories used in roller chains, but they have different functions.
- Joint (joint link): is used to connect the two ends of a chain to close it.
- False link (elbow link): allows for a chain with an odd number of pitches.
False links can reduce the strength of the chain and require special attention in transmissions subject to high stresses.
Both accessories must be chosen based on the pitch and type of chain.
