There are various shapes of the internal circulation structure reverser of linear ball screw, but the commonly used shapes are circular and elliptical. Due to the shorter reverse channel of the circular ball, it is not as smooth as the elliptical structure. The recommended reverser structure is an elliptical inner channel structure, which eliminates the impact of chamfer errors on ball reversal due to the fact that ball reversal does not pass through the screw tooth tip, similar to an external circulation structure.
