Why the medium-light range is the volume tier
Run the load math on a typical working cart — a few hundred to a couple thousand pounds total across four casters with a 2× safety factor — and the per-caster number lands in this band more often than any other. It's wide enough (up to 1,500 lb) to cover real industrial equipment, light enough that everything still rolls easily by hand. The tiles below shop it by capacity and wheel type.
What construction looks like here
Medium-light is where wheel cores move from polyolefin toward cast iron and aluminum as load climbs, and where bearings range from precision ball at the light end to roller bearings near 1,500 lb. Kingpin construction is standard and adequate — the failure modes that justify kingpinless don't appear until heavier loads.
Common questions
What's the difference from light duty?Light duty tops near 300–450 lb per caster. Medium-light goes to 1,500 lb — real industrial equipment, not just office and display rigs.
Can these be hand-pushed?Yes — a four-caster set through ~5,000-6,000 lb total rolls by hand on a decent floor. That's part of why the range is so widely used.
Do I need kingpinless here?No — kingpin construction is standard and sufficient through 1,500 lb per caster.
