In this industrial equipment showcase, we demonstrate the performance and applications of our 4-inch medium-duty castors with lockable black TPU wheels. Understand how the robust dual-axis construction provides superior stability for assembly lines and packaging stations, while the chemical-resistant PP material ensures durability in demanding environments like food processing and pharmaceutical facilities. We'll walk you through the mounting options, load capacity testing, and real-world implementation scenarios to help you evaluate these castors for your medium-duty material handling needs.
