Linear motion is the most basic of all motion. Linear ball bearings provide linear movement in one direction.
A roller bearing, carries a load by placing rolling balls or rollers between two bearing rings called races. These bearings are comprised of an outer ring and several rows of balls retained by cages. Roller bearings are manufactured in two styles: ball slides and roller slides.
