The Integral twin is a swivel castor with central, total lock, designed for demanding medical and industrial applications including anesthesia carts, C-arms, CT scanners, MRI and X-ray equipment, care beds, hospital beds, nursing and retirement homes, surgery robots, surgery tables, and ultrasound systems. The fitting comprises a stem with cam hole for profile bars in short version, with the important caveat that washable beds must be sealed in the fitting area by the hospital bed manufacturer to ensure hygiene and durability. The housing is constructed from medium steel sheet and incorporates a precision ball bearing for smooth swivel operation, providing reliable rotational performance under continuous use. The wheel features a 125 mm diameter and is equipped with a precision ball bearing that is sealed to prevent contamination and ensure longevity in sterile environments. The tread material is polyurethane, injected and electric-conductive, offering excellent grip, durability, and static dissipation properties essential for sensitive medical equipment. The polyamide wheel body provides lightweight strength and chemical resistance. The overall height of the castor is 150 mm, making it suitable for integration into various equipment frames and bases. The load capacity specifications indicate a static load rating of 250 kg, whilst the dynamic load capacity is 125 kg at 4 km/h or 125 kg at 3 km/h, depending on operational requirements and speed considerations for safe equipment mobility in clinical environments.
