Over Loaded Test Of Mid-Heavy Duty Caster

Observe the step-by-step operation and see practical examples of usage. In this video, we conduct a comprehensive overload test of our 4/5/6-inch medium-heavy duty PU wheel casters with threaded stem and swivel top plate. You'll see how the die-cast aluminum core, wear-resistant green PU tread, and precision double ball bearing perform under extreme weight conditions in industrial applications. Watch real-world demonstrations showing load capacity, smooth swiveling, and durability for trolleys, equipment cabinets, and warehouse carts.
