Nylon Sliding Door and Window Rollers Replacement Wheels for Smooth Operation

Structure and Materials: The main body is a metal frame (with different rust-proof treatments such as galvanized or color zinc plating), equipped with two white nylon rollers (with built-in bearings). The bottom features a double-layer adjusting screw structure, allowing for fine-tuning of the roller height to accommodate different track clearances.

Features: The double-wheel design distributes the weight of the door/window, improving load-bearing capacity and sliding stability; the adjusting screws flexibly adapt to track height, reducing jamming; the nylon rollers offer both quiet operation and wear resistance, while the metal frame ensures structural strength.

Applicable Scenarios: Primarily used for medium-weight sliding doors/windows (such as aluminum alloy sliding doors and thermally broken aluminum windows), suitable for the standard door and window needs of residential and commercial spaces. Different surface treatments of the frame can meet the rust-proof requirements of various humidity environments.
