Plastic Window and Door Roller Replacement Parts for Sliding Systems

Structure and Materials: The main body is constructed with a black engineering plastic frame, with some models featuring galvanized metal supports. The rollers are made of wear-resistant plastics such as nylon and polyurethane (available in green, red, orange, etc.), with some models incorporating bearings and spring buffer structures, and an adjusting screw at the bottom.

Features:
Single-wheel type: Lightweight structure, suitable for small doors and windows, lower cost.

Double-wheel type: Distributes weight, improves stability, suitable for medium-weight doors and windows.

With buffer type: Reduces vibration and noise during sliding through springs, improving the user experience.

Adjusting screw: Allows for fine-tuning of the roller height to accommodate different track gaps and reduce jamming.

Applicable Scenarios: These rollers emphasize high cost-effectiveness and are widely used in light-load scenarios such as sliding windows and simple sliding doors in ordinary home decoration. Different sizes and structures are available to accommodate doors and windows of varying weights and sizes, and can also meet the low-cost procurement needs of overseas markets such as Southeast Asia and Africa.
