Roller Column Screw VS Roller Ball Screw The bearing capacity of the rolling screw mainly depends on the radius of curvature of the contact surface between the rolling elements, the number of contact points, and the hardness and finish of the contact surface. Under the conditions of the same hardness, smoothness and precision of the contact surface, the roller screw has more contact points than the ball screw, and the radius of curvature of the enveloping circle of the roller contact surface ...

Deep Groove Ball Bearing Introduction Deep groove ball bearings are very widely used. A deep groove is formed on each inner and outer ring of the bearing enabling them to sustain radial and axial loads in either direction as well as the combined loads which result from the combination of these forces. Deep groove ball bearings are suitable for high speed applications. In addition to the open type, deep groove ball bearings come in a number of varieties, including pre-lubricated bearings, bear...

Angular Contact Ball Bearings Introduction Standard ball bearings steel with content of carbon and chromium was selected and hardended to withstand the intense pressure between the rolling element and bearing rings. Carbonitriding on both inner and outer rings is a basic hardening process for many TPI ball bearings suppliers. Through this special heat treatment, hardness on the raceway surface is increased; which reduces wear accordingly. Ultra-clean steel is available in some of TPI standard...
