ORO 1 Pair of Replacement Wheels Suitcase Wheels for Luggage, Outdoor Inline Skate or Roller 54 x 18 mm Inner Diameter 8 mm, 54 x 18 mm, 54 x 18 mm, 54 x 18 mm, 54 * 18mm

Lovely smooth wheels. The metal part going through the wheels was a bit too long so was able to remove a small bit of case to get wheel to fit properly into the case. Maybe I should have check dimensions of this part before ordering. Used this case on recent trip and it was quiet Andover easy to wheel.

perfect for when your wheely case wheels give up. inline skate type wheels and bearings. alot smoother than most original case wheels.
