Key Features & Specifications
-
Material:
-
Wheel: Typically made from Nylon (PA) or sometimes POM (Acetal). This material is chosen for its durability, low friction coefficient, and quiet operation. It won't rust and is gentle on the aluminum track.
-
Bearing: Sealed Ball Bearings (608ZZ is a very common size). This ensures smooth, quiet rolling and protects the bearing from dust and debris, which is crucial for a low-maintenance, long-life product.
-
Bracket/Frame: Usually made from galvanized or zinc-plated steel for strength and corrosion resistance. The axle that the wheel spins on is also steel.
-
Load Capacity: The 100kg rating is for the entire set. A standard sliding door uses 4 wheels (2 at the top, sometimes 2 at the bottom for guidance), so this set would be sufficient for a very large and heavy door (e.g., a full-length mirror door or a solid wood door).
-
Low Friction Design: Achieved through the combination of:
-
High-quality nylon wheels.
-
Sealed ball bearings that spin freely.
-
Precise engineering for a perfect fit on the track without unnecessary resistance.
-
Compatibility: These wheels are designed to fit into standard "C" or "U" shaped aluminum tracks commonly used in wardrobe sliding door systems. It's crucial to check the dimensions.
What to Check Before You Buy (Critical Measurements!)
To ensure the wheels you buy will fit your existing track and door, you must measure your old wheels or the track system. Here’s what to look for:
-
Wheel Diameter (D): Common sizes are 25mm, 30mm, 35mm, or 40mm. Measure across the wheel.
-
Wheel Width (W) / Groove Width: The width of the wheel that sits inside the track. This must match the internal width of your aluminum track.
-
Total Height (H): The distance from the top of the bracket to the bottom of the wheel. This determines how the door will hang in the track.
-
Axle/Bolt Size: The diameter of the hole in the wheel and the bolt that holds it to the door. A common size is 6mm or 8mm.
-
Bracket Type: Does it have a single hole for a bolt, or is it a specific clip-in design? Match this to your door's hardware.
Typical Applications
-
Sliding Wardrobe/Closet Doors: The most common use.
-
Sliding Room Dividers & Barn Doors: Especially the heavier, solid wood styles.
-
Sliding Cabinet Doors for modern kitchens or entertainment units.
-
Industrial Sliding Partitions.
