Conveyor chain Types And Pitch

A Conveyor chain is chain that has been designed specifically for chain conveyor systems. It consists of a series of journal bearings that are held together by constraining link plates. Each bearing consists of a pin and a bush on which the chain roller revolves.

Types

1. Hollow bearing pin chain
Hollow bearing pin chain allows attachments to be bolted through the hollow bearing pins. Attachments may be tightly fixed or held in a 'free' manner.

2. Solid bearing pin chain
Solid bearing pin chain has the same dimensions as hollow bearing pin chain but is more robust and thus suitable for more arduous conveyor applications.

3. Deep link chain
Deep link chain has deeper side plates than the normal chain plates and so provides a continuous carrying edge above the roller periphery. Deep link chain comes in solid and hollow bearing pin varieties.

4. Drop forged chain
Drop forged chain (also known as en-masse conveyor chain or scraper chain) is already fitted with attachments that have been welded directly onto the chain links.

Pitch

Each type of conveyor chain is available in a range of different pitches. The minimum pitch is dictated by the need for adequate wheel tooth strength and the maximum is determined by plate rigidity. The maximum pitch can be exceeded if the chain is strengthened with bushes between the link plates and there is still enough clearance with the wheel teeth.
