Medical equipment bearings - lubrication-free, cleanroom compatible, medium resistant, corrosion free, low noise - these are important criteria for medical equipment components. Plastic bearings and tow chains with these characteristics are available. Non-lubricated bearings are used in X-ray robots, laboratory equipment, patient chairs, hospital beds and prosthetic limbs, among others. Maintenance-free tow chains are used to protect and guide cables in equipment such as operating room equipment, rehabilitation systems and imaging diagnostic equipment.
