Hearing Grinding Noise or Feeling Friction When KONE Elevator Doors Operate?

Smooth, quiet door operation is a key advantage of KONE elevators. If your elevator doors start emitting continuous squeaking friction noises, rough rolling sounds, or show obvious jamming during opening and closing, the issue likely lies not in the complex control system, but in a critical mechanical door component—the door hanger roller. As essential KONE elevator door parts, these small nylon or composite rollers are responsible for stably supporting and moving the entire door panels along the guide rails. 

Door hanger rollers are typical wear-and-tear parts. Over time, daily friction causes them to deform, develop grooves, or even crack. This leads to rough rolling, noise generation, and increased motor load. Delayed replacement will further damage the more costly guide rails and may cause premature failure of the elevator door operator belt or motor. When replacing, it is recommended to inspect all hanger rollers on the same side and replace them in sets to ensure balanced operation. Choosing KONE elevator spare parts that match the original specifications in size, shaft hole, and material is crucial to guarantee proper door running track and clearance after installation.

For service providers maintaining a large fleet of KONE elevators, stocking commonly-used door hanger roller models as regular KONE elevator spare parts enables quick resolution of this frequent issue, significantly improving maintenance efficiency and customer satisfaction.

If your KONE elevator doors experience operational noise or jamming and you need to purchase original-spec door hanger roller kits, please provide the elevator model or photos of the worn roller for specification confirmation to us, KONE elevator parts supplier!
