Lubrication-free and precise deflection of conveyor belts

iglidur® knife edge rollers

iglidur® knife edge rollers  
Deflection – precise and lubrication-free.

igus® has developed its own knife edge rollers to deflect conveyor belts in materials handling applications. The first standard product range has three iglidur® materials available: the universal iglidur® P210 and the FDA-compliant iglidur® A180 (up to 90°C) and iglidur® A350 (up to 180°C). The iglidur® solution is characterised by tight radii and low driving power requirements.

100% lubrication-free belt deflection

Low drive power

Tight deflection radii

Long service life of the belt

Cost-effective

Long service life


Fields of application: packaging, material handling, automation, food technology.

 
When to use it?

When a lubrication-free conveyor belt is required

When precise guiding is required

When a cost-effective and lightweight solution is required

When not to use it?

When high speeds occur

When high forces are applied on the belts

When a static knife edge is required
