Different types of trolley wheels and castors
Barrow wheels
Typically pneumatic or solid rubber wheels, they're great shock absorbers, so perfect for rolling over uneven surfaces with delicate, bulky loads like furniture, sacks, and heavy equipment. While solid rubber barrow wheels don't roll as smoothly as pneumatic options, they're puncture-proof, so they don't lose air and performance.
Trolley wheels
For flatbed trolleys, stock carts, and nursery cages, exploring the surface type and load capacity is essential for finding the right wheel. Rubber, polyurethane, or nylon, they all have their place depending on where and what they're moving.
Castors (or castor wheels)
Castors come as swivel or fixed units, either free-rolling or with brakes. They make tight turns and secure parking a breeze, making them perfect for stock carts and Danish trolleys.
Rubber wheels
Rubber wheels are grippy and great shock absorbers. Rubber wheels with a deep tread are perfect for outdoor use, soft ground, and uneven paths.
Nylon wheels
Nylon is hard, durable, and chemical-resistant. They're incredibly tough, but their dense, solid composition means they're more suitable for smooth, solid floors like concrete and wood. A larger diameter wheel may handle uneven surfaces better. A quality nylon wheel with a sealed bearing will have a far smoother, longer-lasting lifespan.
Polyurethane wheels
A wheel-type that slots somewhere between nylon and rubber. It provides a slight cushion with low rolling resistance.
Steel or cast-iron wheels
The hardest and heaviest duty wheels. They're used most often in demanding agricultural and industrial environments.
