High Rigidity Crossed Roller Bearings have a one-piece construction for outer and inner rings. Consequently, high rigidity and high precision are achieved. The said bearings can do away with the mounting errors and allow for smooth rotation. High Rigidity Crossed Roller Bearings are perfect for applications where rotation speed gets higher. The said bearings are applicable for the rotating parts of medical equipment, industrial robots, machine tools and many others. Made of steel, these can resist rust and have high strength.
