A KONE elevator door down roller is a door system component used within selected elevator door assemblies. Installed as part of the door mechanism, it works alongside other door-related components during elevator door operation.
Different door systems may require specific roller dimensions and configurations depending on the elevator model and door assembly design. When selecting a replacement door down roller, it is important to verify the existing component specifications to help identify a suitable match.
This category includes door down rollers in a variety of dimensional and mounting configurations to suit different KONE elevator door assemblies:
Selection Tip: Compare the dimensions and mounting details of the existing component when identifying a suitable replacement.
Within a KONE elevator door system, door down rollers are involved in:
1. What is the function of the down roller?
It supports door panel weight and keeps doors perfectly aligned within the sills.
2. What happens if they are completely ignored?
The doors will start to jam or move unevenly. When this happens, the elevator will automatically shut down for safety, trapping people inside or leaving the elevator broken.
3. How do I know if they are broken or wearing out?
You will hear annoying squeaking, grinding or scraping noises whenever the elevator doors open and close.
4. Why do some door down rollers appear similar despite having different specifications?
Rollers can look similar visually while differing in dimensions or mounting arrangements.
