This 8" x 2" Nylon Glass filled caster wheel includes a nylon tread that has been forfeited with glass fiber for excess density and durability. These wheels offer decreased friction, giving it a longer lifespan, and have a great weight capacity with most metal wheels. This wheel is ideal for dollies, platform trucks, shop floors, warehouse carts and freight terminals. These wheels are well-suited for food service carts, hotel housekeeping carts, and industrial and commercial equipment. These are also great for welding carts, and wall panel carts.
