Plastic Window and Door Roller Replacement Wheel for Sliding Track Systems

Structure and Materials: The main body consists of a black plastic frame and a metal core, paired with two orange wear-resistant rollers (usually made of polyurethane). An internal adjusting screw structure allows for fine-tuning of the roller height to accommodate different track clearances.

Features: The dual-wheel design distributes weight, improving sliding stability; the plastic frame is lightweight and rust-resistant, while the metal core ensures structural strength; the adjustable function enhances installation adaptability.

Suitable Scenarios: Primarily used for medium-weight sliding doors/windows (such as aluminum alloy sliding doors and thermally broken aluminum windows), balancing load-bearing capacity, noise reduction, and smooth sliding, suitable for the standard door and window needs of residential and commercial spaces.
