Tired of dragging a broken-wheeled suitcase through airports? This 8-pack of replacement wheels has you covered! Each wheel is 50mm in diameter by 18mm wide, made from wear-resistant polyurethane rubber with metal bearings that roll smoothly and quietly. The package includes everything you need for repair: 8 wheels, 8 of the 30mm axles, 8 of the 35mm axles, 16 axle screws, 20 washers, and 4 wrenches. The double bearing design can handle serious weight while maintaining flexible rotation. Installation is pretty straightforward - you'll need a hacksaw to remove the old wheels at the gap, then install these new ones with the included accessories. Perfect for suitcases, trolley cases, and even works for roller skates or scooters with compatible sizing. Important note though: these aren't universal, so measure your existing wheels carefully before ordering to ensure the hole spacing and shape match. The center bearing internal diameter is 6mm, and total wheel width is 21mm. Seriously, instead of replacing your entire luggage set because of broken wheels, this repair kit can extend the life of your favorite suitcase for a fraction of the cost. Way more economical than buying new luggage, and you'll feel like a genius fixing it yourself. Just make sure to check compatibility first!
