Roller sprockets such as the conveyor chain sprockets are manufactured both in welded version and as one solid part. In addition to this function, the economic efficiency is in this context decisive for the selection of the construction.
In special cases, the welded constructions can also be used as a substitute for cast-iron wheels, since it is not necessary to build an expensive mould. This represents a major economic advantage when replacing it with a spare part.
Sprockets in welded version can be reinforced with spokes and thus convey much larger loads.

It is particularly economical to manufacture the large sprockets in welded version. In this way, a forged ring is welded together with a washer and a hub. Welded ribs and/or spokes are used as reinforcement. Lightening holes are incorporated in the wafer for the purpose of weight reduction.
