# Sidewall bearing pressure

The effect of bends on the pulling force $F_{pull}$ is substantial. Along a route with multiple bends, the greatest pulling force will be developed through the last bend (unless there are slopes or cable pushers involved), as will the greatest sidewall bearing pressure (radial force). If possible, the cable pull should be done from the end with the most severe bends (always check both forward and backwards directions in the cable pulling editor).

The parameters influencing the sidewall bearing pressure are the sidewall pressure factor, the pulling force at the end of the bend, and the radius of the bend.

The approximate results display only the radial forces at the end of the bends (maximum values), while the forwand and backward direction tabs display the radial forces all along the bends.
