Key Features:
- Heavy-Duty Construction: At 770 lbs (350 kg) per caster, the reinforced fork and 4″ (100 mm) wheel handle industrial transport cycles without deflection.
– Iron-Core Polyurethane: Pressed iron core plus PU tread balances load strength 770 lbs (350 kg) with floor-safe contact and long wear life.
– Precision Ball Bearings: Sealed ball raceways cut rolling resistance to a minimum – smooth starts, effortless direction changes and long, quiet service life.
– 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: 5.9″ (150 mm) installed height keeps equipment centers of gravity low and clearances unchanged – mobility without redesign.
