Component description, application environment, function:
The roller is used in escalators and moving walkways as a chain roller or pallet roller. All of the loads which arise due to the intrinsic weight of the components and the weight of the passengers being conveyed are absorbed by the rollers. The escalators and moving walkways are used all around the world under a wide range of very different climatic conditions. This component can also be used in non-lubricated systems.
Design, choice of material, manufacturing technique
One of the requirements placed on the product is to provide a long service life under a wide range of very different climatic conditions. Furthermore, the material is resistant to oil, grease, anti-corrosion agents etc. The rollers are made of PAS-PU H, a thermoplastic polyurethane. This material is characterised by excellent properties like resistance to hydrolysis, high abrasion resistance and resistance to microbes.
Special customer benefits:
- Excellent ride comfort and very smooth and quiet operation
- Resistance to hydrolysis
- Long service life
- Safe and reliable operation
- More cost-effective than a rubber roller with an aluminium hub
