Specify Electric Cylinders with Confidence Use Motion Analyzer to get product life estimates based on your application parameters and industry standard formulas for L 10 ballscrew rating An estimation of the expected lifetime is under ideal operating conditions. Actual lifetime depends on operating conditions such as temperature, dust, feed, acceleration rates, speed, no. of changes in direction of rotation, etc. Similar to fluid power actuators, electric cylinders are designed for axial operating force and counter measures for any radial loading are recommended and always necessary for longer mechanical life. 25
