Key Components:

1. Nylon Plastic Housing

   • Provides lightweight, corrosion-resistant, and low-friction support for the roller mechanism.

   • Nylon is durable, UV-resistant (if reinforced), and reduces noise during operation.

2. White Zinc Alloy Inner Housing

   • Zinc alloy (often Zamak) offers strength, corrosion resistance, and a smooth finish.

   • The "white" coating may refer to a protective zinc plating or powder coating for aesthetics and rust prevention.

3. Sliding Glass Window/Door Double Roller

   • Designed to support heavy glass panels in sliding systems.

   • "Double roller" implies two wheels per bracket for better weight distribution and smoother movement.

4. Nylon Wheel

   • Ensures quiet, smooth rolling with minimal wear on the track.

   • Resistant to moisture, chemicals, and abrasion compared to rubber or plastic alternatives.

5. Stainless Steel Needle Bearing

   • Provides high-load capacity and smooth rotation.

   • Stainless steel resists rust, making it ideal for humid or outdoor environments.

   • Needle bearings reduce friction, enhancing the roller's lifespan.
