These sliding door rollers are designed for use in pairs. The entire housing and bracket are machined as a single piece from thickened stainless steel and feature a built-in wear-resistant roller mechanism. Specifically engineered for heavy-duty aluminum alloy sliding doors, they distribute weight evenly across dual rollers to ensure smooth and stable operation. They are the leading load-bearing sliding hardware components for balcony sliding doors and partition sliding doors.
Stainless Steel Construction
The long, one-piece housing is precision-bent from thickened stainless steel sheet metal, providing a rigid and robust structure that resists bending or deformation even under heavy door panel loads. The stainless steel base material offers excellent rust and corrosion resistance, preventing rust and oxidation in consistently humid and rain-exposed environments, ensuring longer service life outdoors.
Moisture-resistant, rust-proof, and highly durable construction
Wear-resistant rollers with low rotational resistance for smooth operation
Height-adjustment screws for precise fine-tuning of roller height
Enclosed housing prevents dust from entering internal axles
Eliminates issues with sagging doors or floor jamming
Dual-Wheel Load-Bearing Design
The dual rollers are evenly spaced to distribute force uniformly, ensuring stable load-bearing performance. This design accommodates both standard and heavier aluminum alloy sliding door panels, effectively preventing issues such as sagging, tilting, derailment, and difficult operation that may arise from long-term use.
Even force distribution for stable performance
Prevents sagging, tilting, and derailment
Fits standard door and window profile grooves
Industry-standard mounting hole spacing
No cutting or grooving of aluminum profiles required
The overall dimensions fit standard door and window profile grooves, ensuring a secure, wobble-free installation. Utilizes industry-standard mounting hole spacing, eliminating the need to cut or groove aluminum profiles during assembly. This enables convenient and efficient batch assembly at door and window factories, effectively reducing labor costs.
