A Professional Guide to Ensuring Passenger Safety
In modern urban transportation, escalators serve as essential vertical transit solutions in shopping malls, metro stations, and airports. Their operational stability is directly linked to passenger safety. As a key wear component in the escalator chain system, escalator step rollers play a critical role in smooth and reliable operation.
This article provides an in-depth analysis of common step roller failures and recommends high wear-resistance solutions from A-FLY, a globally recognized elevator and escalator spare parts supplier.
1. Common Escalator Step Roller Failure Analysis
Under long-term, high-load operation, escalator step rollers commonly encounter the following issues. These failures not only cause abnormal noise but may also lead to unexpected escalator shutdowns:
Outer PU Layer Separation or Cracking
When polyurethane material quality is insufficient or the escalator operates under prolonged overload conditions, the roller’s outer layer may delaminate or crack, resulting in unstable and bumpy step movement.
Bearing Noise and Seizure
Lubrication failure or dust ingress into the bearing can increase rotational resistance, producing sharp metal-to-metal noise. In severe cases, the roller may seize, accelerating wear on the escalator guide rails.
Uneven Wear and Loss of Roundness
If guide rails are misaligned or roller hardness does not meet specifications, irregular wear (flat spots or oval deformation) may occur, significantly reducing ride comfort and operational smoothness.
2. Why Choose High-Quality Escalator Spare Parts?
During spare parts procurement, many maintenance teams focus primarily on price. However, low-quality rollers often require frequent replacement, increasing labor costs and downtime.
Selecting high-wear-resistant and impact-resistant components significantly extends maintenance intervals and reduces total lifecycle costs.
With over 20 years of industry experience, A-FLY understands the long-term impact of core components on escalator performance. Our rollers not only comply with international safety standards but also lead the industry in wear-resistant material technology.
