Thanks to my knowledge gained in practice, I can easily tell that these casters are the real deal. The polyurethane wheels provide smooth movement even in rough environments, making the work so much easier. The weight capacity is impressive, allowing me to move heavy loads without any worries. However, the installation instructions could use some improvement as they were a bit confusing. Overall, I am very satisfied with my purchase and would recommend these casters to anyone in need of high-quality and durable industrial casters. The category "Casters" in "Material Handling Products" is a must-visit when it comes to this kind of purchase in the Industrial and Scientific field.
