The Omikron twin is a swivel caster with directional lock designed for heavy-duty industrial applications. The unit features a square plate fitting for secure mounting to equipment platforms. The housing is constructed from cast iron, or iron forged, heavy material and incorporates a deep-groove ball thrust roller bearing swivel mechanism for smooth directional movement and reliable locking functionality. The wheel assembly consists of a casting body with polyurethane, casted tread material that provides excellent floor protection and quiet operation, while precision ball bearings ensure smooth rolling performance. The wheel measures 15.75 inches in diameter, and the overall height of the complete caster assembly is 22.44 inches. The unit offers a dynamic load capacity of 24,250.82 pounds at speeds up to 1.86 miles per hour, making it ideal for aerospace industry, airport equipment, and heavy AGV systems where exceptional load-bearing capacity and precise directional control are essential requirements.
