The Integral twin is a swivel castor with central, total lock designed for demanding applications. The fitting features a stem with cam hole for profile bars, with the critical requirement that washable beds must be sealed in the fitting area by the hospital bed manufacturer to ensure proper hygiene standards. The housing is constructed from medium-grade steel sheet and incorporates precision ball bearings for the swivel mechanism, ensuring smooth rotation and long service life. The wheel assembly comprises a polyamide body with an injected polyurethane tread that provides electric-conductive properties, mounted on sealed precision ball bearings for reliable operation. The wheel diameter measures 100 mm, whilst the overall height of the complete castor assembly is 129 mm. Load specifications include a dynamic capacity of 125 kg at speeds of 3 km/h and 4 km/h respectively, with a static load capacity of 250 kg. The unit is washable according to AK-BWA standards, making it suitable for medical and hygiene-critical environments.
