We understand that two logins is an inconvenience and are working to consolidate our systems into one login process. Until we’re able to consolidate the two logins, please follow these guidelines:
Ball screws convert rotary motion to linear motion and/or vice versa. A
ball screw assembly consists of a screw and a nut with recirculating
ball bearings. The connection between the screw and the nut is made by
ball bearings, which roll in the matching ball forms in the screw and
nut. The forces transmitted are distributed over a large number of ball
bearings, giving a relatively low load per ball. Since Ball screws
assemblies use rolling elements they have a low coefficient of friction .
