The Integral twin torsion is a swivel castor with central total lock, featuring a steel sheet housing for heavy duty use and a short version stem with cam hole designed for fitting profile bars. The precision ball bearing swivel bearing allows for smooth 360 degree rotation. The wheel has a precision ball bearing and is made of stainless steel with a diameter of 4.92 inches. The castor has a polyurethane tread injected onto the wheel for quiet movement and traction. With an overall height of 5.91 inches, the Integral twin torsion castor has a load capacity of 275.58 pounds at 3 km/h and a static load capacity of 826.73 pounds. The fitting area must be sealed by the hospital bed manufacturer to allow the castors to be washed for use in washable hospital beds.
