Product type: Sliding window roller assembly for aluminium profiles.
Wheel structure: 7A V-groove roller with an outside diameter of 22 mm, a wheel width of 7 mm, an engineering-plastic housing and a ball bearing or customized bearing option. The final wheel design should follow the approved drawing.
This nylon sliding window roller for aluminium profiles is installed inside the lower sash profile to support and guide sliding window or light sliding door panels. The moulded housing holds the wheel in the intended position inside the aluminium extrusion, while the V-groove follows the window track and helps maintain panel alignment during horizontal movement.
The product information lists an inner ball bearing or customized bearing, a 7A bearing roller structure, an engineering-plastic housing and a tolerance of +/-0.1 mm. The page also confirms that the roller can be developed for aluminium window manufacturers, profile system suppliers, hardware distributors and OEM brands, including Linea 20 and similar South American profile systems.
The product name and Overview describe a nylon wheel option, while the specification table lists POM, reinforced plastic or customized material for the outer wheel. These materials should be treated as possible options, and the final material, grade and bearing construction must be confirmed against the drawing and the actual profile.
Product Applications
This roller assembly is suited to aluminium profile systems where the wheel runs inside a compact lower track and supports a lightweight moving panel. Typical applications include:
-
Aluminium sliding windows: the roller supports the sash inside the lower profile and follows the track during opening and closing.
-
Light aluminium sliding doors: the assembly can guide lightweight door panels when the roller dimensions and load capacity match the door design.
-
Linea 20 aluminium profiles: the housing can be developed for Linea 20 or similar profile systems when the profile drawing and wheel position are confirmed.
-
Balcony glazing systems: the roller can be reviewed for lightweight sliding balcony panels when the track geometry, panel load and outdoor environment are suitable.
