Anti Backlash for CNC: Ball Screws, Bearing Blocks, and Anti Backlash Nuts

By design, ballscrews are intended to be secured at their driven end by a pair of angular contact bearings. The other end of the screw is either left to float free in some designs, or secured by a bearing in such a way that if the screw expands or contracts due to heat, it has the freedom to do so at this end.

Ring and Pinion Gear Selection for Optimal Performance

The easiest method is to have the axle cover removed and physically count the number of teeth on the ring and pinion gears. Then take the number of ring gear teeth and divide by the number of pinion teeth. A ring gear with 41 teeth that meshes with a pinion that has 10 teeth yields 41 ÷ 10 or 4.10:1 axle ratio.
