The Integral twin load is a swivel caster with central, total or directional lock designed for demanding medical and laboratory applications including C-Arms, CT Scanners, MRI, X-Ray equipment, hospital beds, microscopic equipment, surgery robots, and surgery tables. The caster features a stem with cam hole for profile bars in short version configuration, providing secure and versatile mounting capabilities. The housing is constructed from heavy steel sheet material and incorporates a precision ball bearing in the swivel mechanism, ensuring smooth rotation and reliable directional control. The wheel assembly measures 5.91 inches in diameter and features a polyamide body with an injected polyurethane tread, combined with a precision ball bearing for optimal performance and durability. The overall height of the caster is 7.6 inches, making it suitable for integration into compact medical equipment designs. This caster demonstrates exceptional load-bearing capacity with a static load rating of 1653.47 pounds and a dynamic load capacity of 551.16 pounds at speeds up to 2.49 miles per hour, providing reliable performance in both stationary and mobile applications requiring precision movement and stability in healthcare and scientific environments.
