SIGMA IDLERS 

 

Designed and engineered in the UK, our range of idler components for conveyor chain and modular belt systems is developed to provide accurate belt and chain support, controlled tracking, and long service life in continuous-duty conveyor applications. Manufactured from high-quality engineering plastics or stainless steel, each idler is precision-machined or moulded to ensure consistent dimensions, smooth rotation, and reliable performance under demanding operating conditions. 

​

Our conveyor idlers are available in a wide range of specifications, including different diameters, bore sizes, shaft arrangements, and mounting options, enabling precise matching to chain type, modular belt design, load requirements, and conveyor speed. Engineered for dependable operation under varying loads, wash-down conditions, and elevated temperatures, all idlers are designed for durability, low wear, and ease of inspection and maintenance. 

​

Available in multiple materials and finishes, including wear-resistant plastics and corrosion-resistant stainless steel, these idlers are suitable for food processing, packaging, manufacturing, and materials handling applications where hygiene, reliability, and consistent belt support are critical.

​

Sigma Industries also specialise in the rapid manufacture of bespoke idler solutions for conveyor chain and modular belt systems. Tight manufacturing tolerances and repeatable build quality ensure accurate fitment, smooth operation, and straightforward replacement—helping to reduce downtime, simplify maintenance, and support fast order turnaround.
