The frame of this double-wheel slider for sliding doors is precision-crafted from thickened stainless steel and features built-in wear-resistant rubber-coated rollers. Designed for use in pairs on heavy-duty sliding door panels, the dual wheels distribute the weight evenly, ensuring smooth and stable operation.

This load-bearing sliding hardware system is specifically designed for aluminum alloy sliding doors, providing reliable performance for demanding applications.

The entire slide track bracket is manufactured from thickened stainless steel, providing exceptional rigidity and resistance to bending or deformation under pressure. The construction resists rust and oxidation even in humid environments typical of balconies and exterior applications.

Rollers feature an outer layer wrapped in highly wear-resistant, flexible material that ensures quiet operation, excellent smoothness, and resistance to repeated rolling friction—minimizing wear and cracking over time.

• Height Adjustment System: Internal height-adjustment screws allow for fine-tuning of roller height, making it easy to correct door panel height discrepancies and gap misalignments
• Precision-Polished Axles: Ensure rollers rotate smoothly without jamming or sticking
• Dust-Proof Sealed Design: Prevents dust and debris from entering the interior mechanism, ensuring long-lasting, smooth operation

The dual-wheel side-by-side configuration ensures stable load distribution and prevents door panel tilting. Two rollers arranged in parallel evenly distribute the load, providing exceptional load-bearing performance suitable for heavy sliding doors.

This advanced design effectively prevents common issues such as door sagging, misalignment, track jamming, and difficult operation. The long, one-piece frame fits snugly into profile grooves, ensuring secure installation without wobbling.

Standard dimensions are compatible with the vast majority of aluminum profiles used in sliding doors and windows. This universal fit eliminates the need to cut or slot profiles, enabling high-efficiency bulk assembly for door and window manufacturers while saving valuable labor hours.

Suitable for a wide range of applications including:

• Aluminum alloy balcony sliding doors
• Interior partition sliding doors
• Commercial sliding entrance doors

Available for bulk procurement and supply to home improvement retailers, commercial construction projects, and the international door and window trade.
