Complete solutions for the C-arm

The customer gave us the task: the highest picture quality possible whilst putting the patient under as little stress as possible. The aim was to find a linear guidance system that enables the x-ray tube to be positioned above the C-arm smoothly and precisely and that is both resistant to radiation and operates with little noise.

The solution comes from the Schaeffler Group – it is ready to install, technically brilliant and provides the customer with significant economic benefits. The basis of the new curved guidance system is an aluminum extruded section with hardened shafts made of corrosion-resistant steel. The integrated locating and non-locating bearing solution is particularly innovative. It means that any dimensional inaccuracies in the adjacent construction can be compensated. The non-locating bearing is designed as a profiled track roller with a movable inner ring, namely as a needle roller bearing – one of our specialties.

The benefit is constant displacement resistance, irrespective of the position of the x-ray tube.
