SIGMA SPROCKETS for PLASTIC CHAIN 

 

Designed and engineered in the UK, our range of sprockets for plastic conveyor chain is developed to provide accurate chain engagement, efficient power transmission, and long service life in continuous-duty conveyor systems. Manufactured from high-quality engineering plastics or stainless steel, each sprocket is precision-machined or moulded to ensure accurate tooth profiles and consistent pitch, promoting smooth chain tracking and reduced wear.

​

Our plastic chain drive sprockets are available in multiple specifications, including a range of tooth counts, bore sizes, hub configurations, and mounting options, allowing precise matching to chain type, shaft size, load requirements, and conveyor speed. Offered in both solid and split sprocket designs, split sprockets enable quick installation and replacement without removing the shaft, significantly reducing maintenance time and downtime.

​

Engineered for reliable operation in wash-down, abrasive, and high-temperature environments, these sprockets are designed to minimise chain stress while remaining easy to align, inspect, and maintain. Material options and surface finishes provide excellent wear resistance and corrosion protection across demanding operating conditions.

​

Sigma Industries also specialise in the rapid manufacture of bespoke sprockets for plastic conveyor chain. Tight manufacturing tolerances and repeatable build quality ensure accurate fitment, consistent performance, and straightforward replacement—supporting efficient maintenance, reduced downtime, and fast order turnaround.
