The Integral twin is a swivel caster 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. The housing construction utilizes medium-grade steel sheet with precision ball bearing swivel mechanism for smooth operation and durability. The wheel assembly incorporates a polyamide body with injected polyurethane tread that provides electric-conductive properties, mounted on sealed precision ball bearings for reliable performance. The wheel diameter measures 3.94 inches with an overall caster height of 5.08 inches. Load specifications include dynamic capacity of 275.58 lb at speeds of 1.86 mph and 2.49 mph respectively, while static load capacity reaches 551.16 lb. This caster is washable according to AK-BWA standards, making it suitable for medical and hygiene-critical environments.
