Let's be direct about what this 55mm wheel kit does.
It carries weight better.
A 55mm lower wheel has a larger contact surface and better leverage than smaller diameters. That means a 40kg door feels like 25kg. Your customers won't know the math – they'll just notice the door glides with less effort.
It lasts longer.
Larger wheels rotate slower at the same sliding speed. Slower rotation means less wear on the bearing and the wheel surface. This kit is built for years of daily use, not months.
It installs without confusion.
We colored the upper wheel hubs black and the lower wheel hubs white for one reason: so nobody has to think. Upper goes on top. Lower goes on bottom. That's it.
It looks like it belongs.
Silver-white metal doesn't compete with your door design. It just sits there, doing its job, looking clean. No brass. No gold. No fake chrome. Just honest silver-white.
Wardrobe sliding door manufacturers who want fewer warranty calls. Contractors who don't want callbacks. Distributors who want repeat orders. And anyone who has ever been annoyed by a sticky, wobbly, or noisy wardrobe door.
One door. One box. Four wheels. No drama.
