The Integral twin is a swivel castor with central, total or directional lock designed for professional 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. The housing is constructed from medium-grade steel sheet and incorporates a precision ball bearing swivel mechanism for smooth operation. The wheel assembly consists of a polyamide body with injected polyurethane tread that provides electric-conductive properties, supported by sealed precision ball bearings for reliable performance. The wheel diameter measures 100 mm with an overall height of 129 mm. Load specifications include dynamic capacity of 125 kg at speeds of 3 km/h and 125 kg at 4 km/h, with a static load capacity of 250 kg. The castor is washable according to AK-BWA standards, making it suitable for healthcare environments requiring stringent hygiene protocols.
