Product Description
Heavy-Duty Sliding Door Four-Wheel Nylon Casters
These long, four-wheel load-bearing casters feature a one-piece, thickened engineering plastic housing paired with four sets of silent nylon rollers. Designed specifically for large, heavy-duty sliding doors and balcony partition sliding doors, the four wheels distribute the load across multiple points for enhanced load-bearing capacity. They ensure smooth, quiet operation and are specialized sliding hardware components for heavy door panels.
Material & Construction Features
- High-strength engineering plastic housing with wear-resistant nylon wheels
- Durable, weather-resistant construction for quiet and smooth operation
- Thickened, impact-resistant engineering plastic through single-piece injection-molding
- Exceptional toughness that resists crushing, cracking, and deformation
- Rust-proof and corrosion-resistant, even in humid balcony environments
- Low friction coefficient nylon wheels for minimal wear and long service life
- Rust-proof metal axle structure with independent wheel rotation
- Moisture-resistant and acid/alkali-resistant for all-weather home use
Load-Bearing & Structural Advantages
The integrated, elongated four-wheel arrangement provides stable load-bearing capacity suitable for heavy-duty door panels. With four wheels arranged side-by-side in an even pattern, load-bearing capacity is significantly enhanced compared to single- or double-wheel configurations.
This design securely supports thick, heavy aluminum alloy sliding doors, effectively preventing common issues such as door sagging, tilting, and sticking during operation. The one-piece, elongated structure is perfectly integrated into the profile groove, ensuring a tight fit with minimal wobble.
Installation & Compatibility
Standardized, universal profile groove dimensions eliminate the need for additional grooving or cutting of profiles, enabling convenient and efficient bulk assembly at door and window factories and effectively reducing labor costs.
Applications
- Heavy-duty aluminum alloy and PVC-U profile balcony sliding doors
- Living room partition sliding doors
- Large-span commercial sliding doors
- Courtyard sliding doors
- DIY home renovation projects
- Real estate project installations
- Bulk procurement for international door and window trade
