Chapter 13--Responsibility Accounting and Transfer Pricing in …

To produce the "S" bearing, Ball Bearing Division must give up production and sale of 1,000 "T" bearings. These 1,000 bearings generate $20,000 of contribution margin: [1,000 ($50 - $30) ]. The sales price would have to be high enough to recoup both the variable costs of the "S" bearings and the contribution margin that is forfeited on the 1,000 units of "T" bearings: $60 …

Ball Screw: What Is It? How Does It Work? Lead Screws

The ball bearings, or the balls, are the most prominent component of the ball screws that moves between the clearance of the nut and the shaft. They make up the component dedied to reducing the friction generated by the nut and the moving screw; this friction would be too great if the balls were not present in the screw assely.
