Metal Double Roller (TS143)

Description

Alaks TS143 Double‑Wheel Metal Roller (Bearing)

The Alaks TS143 double‑wheel metal roller is a key hardware component used in Thermal Break Sliding 143 doors and windows. This roller is specifically engineered to support heavy loads and ensure smooth, stable movement of aluminum thermal‑break sashes. Its design is fully compatible with the frame and track structure of the 143 sliding system.

With a durable all‑metal construction, dual reinforced wheels, and a high‑quality internal bearing, this model efficiently distributes the weight of heavy sashes (including double‑ or triple‑glazed units) along the track. This prevents vibration, excessive wear, or derailment of the sash during operation.

Lift & Slide Doors and Windows:

The Lift & Slide system is one of the most advanced double‑glazed window and door solutions. Its mechanism combines two movements: lifting and sliding. When the handle is turned, the sash lifts slightly off the frame to reduce friction, then glides smoothly along the track.

Compared with traditional sliding systems, Lift & Slide doors and windows offer significantly better thermal insulation, sound insulation, and security. They are designed to support large and heavy sashes while occupying minimal space. In addition, the system allows secure ventilation by enabling the sash to lock in a partially open position.

In this mechanism, the sash moves along rails supported by specialized rollers that guarantee smooth, balanced, and vibration‑free movement. When the handle rotates, the sash lifts approximately 5 mm from the frame (Lift stage). Once released, the rollers allow horizontal movement to the left or right (Slide stage). This technology makes Lift & Slide systems ideal for luxury buildings, large architectural openings, and modern construction projects.

For large Lift & Slide doors where each sash may weigh hundreds of kilograms, standard hardware is insufficient. Specialized hardware components are essential for proper performance. Choosing high‑quality hardware improves functionality, safety, and overall durability.

The Alaks double‑wheel metal roller is engineered to handle heavy loads, featuring a steel body and reinforced wheels, making it a perfect complement for TS143 Lift & Slide systems.
