KONE elevator door rollers and sheaves are important mechanical components used in elevator door systems and traction mechanisms. These parts support the smooth movement of elevator doors and help maintain reliable elevator operation within residential, commercial and public buildings.
Door rollers are used to guide and support the movement of elevator car doors and landing doors during opening and closing cycles. Their role helps reduce friction, support door alignment and contribute to consistent door operation.
Sheaves are grooved wheel components used within traction elevator systems. They work together with hoist ropes or belts to support the movement of the elevator car and counterweight. As part of the elevator drive mechanism, sheaves play an important role in maintaining controlled elevator travel and system performance.
The available range includes door rollers, car door rollers, and sheave components in various specifications:
Note: Review the roller dimensions and bearing configuration to identify a suitable replacement.
1. What is the function of a KONE elevator door roller?
A KONE elevator door roller helps guide and support the movement of elevator doors during opening and closing operations.
2. What does a sheave do in a KONE elevator system?
A sheave is a grooved wheel component that works with hoist ropes or belts to support elevator car movement within a traction elevator system.
3. Are door rollers and sheaves used in different parts of the elevator system?
Yes. Door rollers are typically used within elevator door mechanisms, while sheaves are used within the traction and drive system.
4. What can happen when elevator door rollers become worn?
Worn door rollers may affect door movement, alignment, or overall door operation, making timely replacement important for system performance.
5. Why is sheave condition important in traction elevators?
The sheave works directly with hoist ropes or belts, making it an important component in elevator movement and traction system operation.
