  • Selecting and Applying Rolling Element Linear Bearings

    Linear Bearings: Load/Life Calculation Linear bearings undergo reciprocating rather than rotary motion so that accelerations are much higher than typically experienced by rotary bearings. Since linear bearings have become important primarily as a result of robotic automation, one must often refer to manufacturer's literature for load/life formulas.
