When is static load capacity important?
When both forces and moments are present the combined static load (also referred to as equivalent static load) should be calculated and used to determine the static load safety factor In addition as a general rule if the applied load is less than 2 8 times the preload force on the bearing then the preload force must be considered in the
How much load can a ball screw carry?
Nov 25 2011There are generally two figures given for a particular ball screw the dynamic load capacity and the static load capacity Do they mean that you can put a load up to to the dynamic capacity on the ball screw wile it's running or a load up to the static capcity wile it's not? No to both! The dynamic capacity is just a figure to calculate
