Key Features:

- Medium-Duty Balance: 180 lbs (80 kg) rating with 4″ (100 mm) wheel – the sweet spot between effortless rolling and genuine load strength.
– High-Strength Polyurethane Tread: Denser High-Strength Polyurethane formulation withstands heavier loads 180 lbs (80 kg) and abrasion, extending service life in demanding daily use.
– Plain-Bore Hub (Bearingless): The simple machined bore runs directly on the axle – the most economical, shock-tolerant and maintenance-free construction for light duty.
– Full-Swivel Raceway: Hardened ball raceway gives effortless 360° pivoting, letting heavy loads spin in their own footprint for tight-aisle work.
– Compact Overall Height: 5.2″ (133 mm) installed height keeps equipment centers of gravity low and clearances unchanged – mobility without redesign.
