A real bargain for you: This one is strong and sturdy. Manganese raceway and Dust proof ring are not something you'll see everyday. This one will last very long at minimum maintenance effort. The wheel is soft and protected by 2 covers.
CNC-machined precision raceways and precision tapered secondary load bearings combine to make the casters rugged and easy swiveling. With PU tread wheel, the casters will create less noise and help protect your surface.
