Fermator Door Roller 48*14*6002*M12

Threaded Rolling Guide Component for Elevator Door Systems

Product Overview

The Fermator Door Roller 48*14*6002*M12 is a rolling guide component designed for elevator automatic door systems requiring threaded mounting installation. It supports smooth and stable door movement while providing secure mechanical fixing through the integrated M12 threaded structure.

In maintenance projects across regions such as Germany and Chile, this roller type is commonly used in Fermator door systems where installation stability and long-term mechanical reliability are important. Because the roller operates continuously during door cycles, stable mounting directly affects movement quality and operational consistency.

The integrated 6002 bearing structure helps maintain smooth rolling performance under repeated operation conditions.

Function in Door System

The door roller mainly supports:

• smooth rolling movement along the guide track
• reduction of operational friction
• stabilization of door panel travel
• secure mechanical positioning through threaded installation

Stable rolling and fixing performance are both important for automatic door operation.

M12 Threaded Structure

The key feature of this model is the integrated M12 threaded mounting design.

Compared with standard roller structures:

• threaded installation improves fixing stability
• installation positioning becomes more secure
• movement consistency is easier to maintain
• mechanical looseness is reduced during long-term operation

This structure is commonly used in door systems requiring stronger mounting support.

Mechanical Characteristics

The 48146002*M12 configuration is typically associated with:

• compact but stable roller structure
• integrated bearing support
• threaded mechanical fixing
• suitability for automatic door operator systems

Correct installation torque and alignment are important for long-term performance.

---

Application Context

This roller is commonly used in:

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

In high-frequency elevator environments, stable roller mounting helps reduce vibration and abnormal movement during operation.

---

Common Maintenance Situations

Technicians may inspect or replace the roller when:

• rolling movement becomes unstable
• installation looseness appears
• door vibration increases
• bearing wear affects movement smoothness

Replacing worn rollers often improves both movement quality and operational stability.

---

Practical Notes

From a maintenance perspective:

• threaded fixing should be properly tightened
• roller alignment directly affects door travel quality
• bearing wear may increase operational noise

Correct installation is just as important as the roller itself.
