British Standard Conveyor Chain

Data Sheet - Download it here

British standard conveyor chain is the United Kingdoms ‘standard’ chain specification. The British standard conveyor chains are manufactured to imperial dimensions, with the pitch always measured in inches. The width of the chain is narrower than its European rivals and the round parts are not flatted. The narrower gauge increases the bearings loads on the pin, although this is counter acted by using larger diameter round parts for the pin bush and roller. Not flatting the round parts means, in some circumstances, it is possible for the round parts to spin within the link plates. Flatting the components also has the advantage of preventing the link plates from moving along the pin or bush. In British standard conveyor chains, the round parts are slightly stepped in order to prevent link plate movement. This reduction in diameter at the link plates also has the added benefit of increasing the breaking load of the link plates.

However these differences, when compared to its European rivals, do come with advantages. The narrow gauge of the conveyor chain means that it can run on narrower tracks or in narrower troughs, while its cost is lower due to the reduction of bar and tube required to manufactured the same length of chain. The cost of the British standard conveyor chains is further reduced by saving on machine time, by producing stepped rather than flatted round parts. The final advantage worth noting, is the option to use screw type connecting links as standard on British standard chain, as the pins are parallel. It is possible to use a screw type connecting link pin on flatted metric chains, by only flatting the non-threaded end of the pin.

For cheaper, lower quality British Conveyor Chains, the round parts can be made parallel (i.e. no step down at the link plate) or the hollow round parts (such as the bush or hollow pins) can be rolled rather than machined. With modern automated machining centres, it is now uncommon to find this type of construction due to the risk of link plates moving into the chain during operation, difficulty in achieving good chain rivets as the link plate position varies from pin to pin and the irregular nature of the rolled components.
