Sealed conveyor chains

Polluted conveyor chains chain hinges can lead to increased wear and tear or prevent the chain from being lubricated effectively

When a conveyor chain must operate in a dirty environment, it is often undesirable that this dirt also enters into the hinges of the chain. Polluted chain hinges can lead to increased wear and tear or prevent the chain from being lubricated effectively. A possibility to prevent this debris from entering the hinge of the chain is the application of a seal between the inner and the outer plates. There are various possibilities, such as an O or X-ring seal, possibly in combination with a labyrinth seal. These chains are often designed with an internal lubrication channel.
