Idler Rollers are used in all web processing industries with different designs to suit particular web materials and applications.

 

The primary function of Idler Rollers is to provide continual web tension and to ensure that during line speed variances that the roller rpm matches the web speed.

 

 

Aluminium Idler rollers are generally used where low inertia and the mass weight of the roller are important ensuring that roller will perform at the required line speeds and tensions demanded by the application.

 

Steel Idler Rollers are used when high tension levels and process speeds exist in web processing applications.
