Inflated trolley wheel diameter 300 mm with bearings (tyre 4.00-4).
The hub measures 25 mm diameter and adapts therefore to an axle of 20 mm.
This pneumatic wheel is mounted on a polypropylene rim.
It is perfectly suited to even and uneven floors as well as the garden (lawn, grass, pebbles, earth). In effect, its inflatable pneumatic tyre makes it suitable to go almost anywhere.
It can adapt to the majority of products available on the market such as trolleys or carts for example.
If your axle has a smaller diameter, you can opt for the model with the 20 mm bore or otherwise opt for a reducer on the hardware store page.
