Super precision cylindrical roller bearings are primarily used in machine tools and other precision applications requiring superior bearing performance. In these applications, a high degree of system rigidity is one of the main performance challenges, as the magnitude of elastic deformation under load determines the productivity and accuracy of the equipment. Another performance challenge is keeping the amount of friction and heat generated by the bearing to a minimum during high-speed operation. The bearings are characterized by:

• high-speed capability
• high load carrying capacity
• high stiffness
• low friction
• low cross sectional height
