Fermator Door Roller 48*14*6002 2RS

Rolling Guide Component for Elevator Door Systems

Product Overview

The Fermator Door Roller 48*14*6002 2RS is a rolling guide component used in elevator automatic door systems to support smooth horizontal door movement. It is commonly installed within the door operator mechanism where stable rolling contact is required during opening and closing cycles.

In maintenance projects across regions such as Italy and Chile, this type of roller is frequently replaced after long-term operation due to continuous mechanical wear. Proper roller condition is important for maintaining smooth door travel and reducing operational noise.

The integrated 6002 2RS bearing structure helps improve rolling stability during repeated door movement.

Function in Door System

The door roller mainly supports:

• smooth horizontal door movement
• rolling guidance along the track
• reduction of friction during operation
• stabilization of door panel travel

Unlike sliding guide components, rollers reduce resistance through rotational movement.

---

Mechanical Characteristics

The 48*14*6002 2RS configuration is typically associated with:

• compact roller structure
• integrated bearing support
• stable rolling performance
• suitability for automatic door systems

Correct size matching is important for maintaining door alignment and movement quality.

Difference from Door Shoe Components

Although both are guide-related components:

• Door Shoe → sliding guidance
• Door Roller → rolling movement support

Rollers are mainly used where smoother and quieter movement is required during repeated operation cycles.

---

Application Context

This roller is commonly used in:

• Fermator automatic door systems
• passenger elevators
• commercial and residential buildings
• maintenance and modernization projects

In high-frequency elevator environments, rollers are considered wear-related components and may require periodic replacement.

---

Common Maintenance Situations

Technicians may inspect or replace the roller when:

• door movement becomes noisy
• vibration increases during operation
• rolling movement becomes unstable
• bearing wear appears after long-term use

Replacing worn rollers often improves overall door movement smoothness.

---

Practical Notes

From a maintenance perspective:

• roller condition directly affects door movement quality
• bearing wear may increase operational noise
• correct dimensions are important for proper installation

Even small deviations in roller size may affect track alignment.
