Ball Screw Selection | Thomson®

Ball Screws. The ball screw drive is an assely that converts rotary motion to linear motion (or vice versa). It consists of a ball screw and a ball nut packaged as an assely with recirculating balls. The interface between the ball screw and the nut is made by balls which roll in matching ball forms. With rolling elements, the ball screw

Types of Bearings | Uses & Working Mechanisms Explained

Aug 25, 2020· Ball bearings are one of the most common types of bearing classes used. It consists of a row of balls as rolling elements. They are trapped between two annulus shaped metal pieces. These metal pieces are known as races. The inner race is free to rotate while the outer race is stationary.
