These spindle systems utilize rounded balls or rollers to minimize surface contact and uses low friction coefficient lubricants to rotate the shaft. Used most commonly in the manufacturing industry, the bearings are fitted on both sides of the drive shaft to be used at high speeds (generally under 40,000 RPM)
