The Integral assist is a swivel caster with central, total, or directional lock, specifically engineered for electromobility applications requiring reliable maneuverability and precise control. This caster features a stem with cam hole for profile bars in short version, enabling seamless integration into medical and healthcare equipment. The wheel measures 5.91 inches in diameter and is constructed from cast polyurethane, providing excellent durability and floor protection in demanding hospital environments. The housing is fabricated from steel and iron, ensuring robust structural integrity and long-term performance. This caster is ideally suited for use in anesthesia carts, C-arms, CT scanners, MRI systems, X-ray equipment, computers on wheels, dialysis carts, hospital beds, medication carts, nursing carts, stretchers, ultrasound systems, and ventilators. The locking mechanism offers operators enhanced safety and stability when equipment must remain stationary, making it an essential component for healthcare facilities and nursing and retirement homes where equipment positioning and security are critical operational requirements.
