xiros guide rollers with FDA conformity: 60% weight saving compared to metallic solutions

Shery George | 21 January 2022

igus, develops maintenance-free and above all lubrication-free solution for transport and guide rollers, which are made of blue light weight PVC tube and FDA-compliant two fixed flange ball bearings made up of in-house material xirodur B180 and stainless steel balls under the brand name xiros. 

These xiros guide rollers  are particularly important for labelling, packaging and food applications due to possible contamination of food. 

Plastic solution to save drive force-

The PVC tube weighs only about one third as much as comparable stainless steel tubes. This has a positive effect on the required drive force when the rollers are set in motion. Due to the fact that xiros polymer ball bearings are lubrication-free, the balls do not run against the resistance of the lubricant; unlike their metal counterparts. The advantage is that they can be set in motion much more easily than metal ball bearings due to the low friction.

A complete range of Xiros guide rollers-

Apart  from PVC tube material,  xiros® guide rollers are available in various tube materials like  aluminiumstainless steel & carbonWith diameters from 20 to 100 mm and lengths of up to 1,500 mm. Special parts such as ready-to-install systems with shafts are also possible.

Advantages of  Ready-to-install film guide rollers  from Igus .

  1. As they are  lubrication free, the torque  required is  much lower then metallic lubricated bearings  solution.
  2. Special sand blasted rollers  are  also  available to get better grip and avoid film from slipping.
  3. Special bearings with a projecting flange that prevents the film from jumping over can also be used. 
  4. Lengths and diameters are also very flexible – we have a wide range of standard bearings to draw on. 
  5. Predictable life of  rollers by expert  calculation.

What is the service life of a guide roller?

Ultimately, the question remains: “How long will the roller last?”

Our calculation tools can determine the answer for your application. External influences, such as contamination and cleaning media, are taken into account during selection of components and materials used.
