What Are the Types of Escalator Rollers and Their Functions?
In an escalator system, rollers are among the most essential components ensuring smooth and stable operation. Whether it’s the movement of the steps, handrails, or drive mechanisms, all rely on precise coordination between different types of rollers. The performance of these rollers directly affects the escalator’s stability, noise level, and service life.

Here, the technical team from A-FLY Elevator & Escalator Parts Supplier introduces the main types of escalator rollers and their respective functions.
1. Escalator Step Roller
Escalator step rollers are installed at both ends of each escalator step.
They support the step as it moves along the track while bearing the passenger’s weight.
Main Functions:
Ensure smooth and stable step movement
Reduce noise and vibration
Maintain load-bearing capacity and structural balance
High-quality step rollers are made of wear-resistant polyurethane or nylon with high-precision bearings.
A-FLY provides a variety of escalator step roller sizes compatible with major global brands.
2. Escalator Step Chain Roller
Escalator step chain rollers are mounted on the main drive chain and connect each step to achieve synchronized motion.
Main Functions:
Maintain uniform step movement
Reduce chain friction and extend lifespan
Improve the overall stability of operation
A-FLY’s step chain rollers feature reinforced steel cores with wear-resistant rubber layers, delivering low noise and high durability — ideal for high-traffic areas such as malls and metro stations.
3. Escalator Guide Roller
Escalator Guide rollers help direct the steps, handrails, or chains along the correct path within the guide rail system, preventing misalignment or jamming.
Main Functions:
Provide lateral support and guidance
Prevent derailment and ensure stability
Reduce friction and extend track lifespan
All A-FLY escalator guide rollers undergo precise dynamic balancing tests to ensure stable performance even under high-speed operation.
4. Escalator Handrail Drive Roller
The handrail drive roller is part of the handrail drive unit. It drives the handrail belt in synchronization with the step movement, ensuring passenger safety and comfort.
Main Functions:
Transmit driving power for synchronized operation
Increase friction and prevent slippage
Enhance comfort and safety during use
A-FLY offers a complete range of handrail drive wheels and pressure rollers featuring anti-slip rubber coating technology, providing quiet, smooth, and durable performance.
5. Escalator Tension and Pressure Rollers
Escalator tension and pressure rollers are typically installed in the drive or handrail system to maintain proper belt or chain tension.
Main Functions:
Adjust chain or belt tightness
Absorb vibration during operation
Improve overall system stability and durability
A-FLY provides various tension roller solutions adaptable to different escalator brands and models.
6. The Importance of Escalator Rollers
Though small in size, rollers play a critical role in the entire escalator mechanism.
High-quality rollers help reduce friction, lower noise, and extend the lifespan of major components like chains, guide rails, and motors.
Choosing reliable parts from a trusted supplier is the first step for maintenance engineers and project managers to reduce repair costs and ensure long-term reliability.
