Industrial Spiral Screwed Idler

Products Description

Designed with innovation as a main focus, the steel spiral return rollers significantly prolong the lifespan of conveyor belts. Featuring a steel spiral wrapped around a conventional roller body, this design helps to avoid direct interaction between the conveyor belt and the roller's steel surface. Instead, the spiral steel touches the conveyor belt, dislodging sticky substances and minimizing belt wear. This innovative approach not only maintains the belt's cleanliness but also greatly prolongs the durability of the belt's exterior.

The spirals can have different shapes, dimensions and directions (left or right rotation) and can be made of different materials. Our portfolio includes conveyor rollers with spirals made of steel and wear-resistant polyurethane (PU).

We particularly recommend the rollers with PU spirals for use in the lower run of belt conveyors for bulk material handling.
