Welcome to our newly redesigned website!
The Omikron twin is a swivel castor with directional lock designed for demanding industrial applications. The castor features a square plate fitting for secure mounting to equipment bases. The housing is constructed from 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 comprises a cast iron body with polyurethane, casted tread material, providing excellent durability and floor protection, whilst precision ball bearings ensure smooth rolling performance. The wheel diameter measures 400 mm and the overall height of the complete assembly is 570 mm. The castor offers a dynamic load capacity of 11,000 kg at speeds up to 3 km/h, making it suitable for heavy-duty applications including airport equipment and AGV systems where reliable mobility and directional control are essential.
