Escalator Rollers - the Key to Quiet Operation
Maintaining smooth passenger flow requires the efficiency of hundreds of components, but it is the escalator rollers that determine the comfort of the ride and the longevity of the track. Every day, hundreds of steps move on thousands of rollers that must withstand immense pressure forces, variable weather conditions, and vibrations. Our wholesaler offers only specialized running elements characterized by optimal polyurethane hardness, precise bearing placement, and fatigue resistance compliant with UDT requirements.
Escalator Step Rollers - FAQ
Escalator rollers operate under tremendous dynamic load. Improper material (e.g. too soft polyurethane) leads to rapid deformation, vibration, and bearing damage, resulting in noise and the need for costly track repairs.
The rollers take over the weight of the steps and passengers, transferring it directly to the running rails. Each guiding roller for the stairs is responsible for maintaining the proper geometry of the steps in the track, preventing them from skewing and coming into contact with the balustrade structure.
In most cases, no. Each manufacturer (Otis, Schindler, Kone, ThyssenKrupp) uses unique diameters, tread widths, and bearing systems. Selection must be based on the catalog number or precise technical dimensions.
Do najczęstszych objawów należą: zwiększony poziom hałasu (huk, pukanie), odczuwalne drgania stopni podczas jazdy, nierównomierny ruch oraz widoczne zużycie (wykruszenia) bieżni poliuretanowej.
Tak, większość oferowanych przez nas rolek do schodów ruchomych jest wyposażona w wysokiej klasy łożyska toczne, które są fabrycznie zabezpieczone i przygotowane do długotrwałej pracy w warunkach dużego obciążenia.
Types of Rollers Used in Close Transport Systems
In modern devices, several basic types of rollers are distinguished, each serving a different function in the traction system. At MPPR, we provide complete service sets including:
- Step Rollers: They directly bear the load from passengers and the step's own weight. Their treads must be resistant to wear and flattening to avoid annoying "knocking" when the step passes through the track curve.
- Each Stair Leading Roller: This is a critical safety element. The stair leading roller maintains a constant distance between the step and the handrail, preventing the device from jamming. A properly functioning stair leading roller eliminates lateral vibrations.
- Chain Rollers: They work in the step chain system, ensuring smooth transmission of driving force without unnecessary jerks.
Material Technology - Why Our Rollers Are Durable?
The key to success is polyurethane treads. Our rollers for escalators use polyurethane with high resistance to material fatigue (rebound resilience). By using cores made of high-strength steel or composites, we avoid problems with the tread "flowing" due to heat generated during friction. Every stair leading roller in our offer features certified ball bearings sealed to prevent the penetration of metallic dust and contamination from device operation.
Support for Maintainers and Service Teams
We understand that downtime of escalators in commercial buildings leads to financial losses and a decline in customer trust. That's why we offer rollers for escalators compatible with devices from brands like Otis, Schindler, Kone, ThyssenKrupp, and O&K. We have warehouse stocks enabling fast processing of "urgent" orders. If you are unsure which stair leading roller is suitable for your model, contact our technical department. We will help you select components based on the production year, O.E.M. number, or technical dimensions, ensuring full compatibility with your installation.
