In this video, we take a focused look at the specifications and what they mean in practice for our 4/5/6 inch medium-duty swivel polyurethane caster wheels. You'll see a detailed demonstration of the side brake mechanism, 360-degree swivel functionality, and double ball bearing system in real workshop conditions. We'll show you how these casters perform on various surfaces and explain how the polyurethane tread provides both floor protection and noise reduction for industrial applications.
