Donghua Limited is proud to be the only chain manufacturer in the UK to have its own hot dip lubrication bath.

Once produced, our attachment chain is dipped in a metal vat containing hot lubrication which penetrates into the bearing areas that standard lube spraying would not reach. As the chain cools, the surplus lube drains away leaving an oil deposit inside the chain providing ultimate lubrication properties – this initial lubrication is the most important a chain receives and helps significantly extend wearlife.

The chain is then preloaded, measured and matched as necessary.
