Load is force applied to a part when in operation.Preload is applying force before operation. In this context it is slight pressure applied to the bearing to remove play by pushing the races closer together. Preload is applied via the installation of the cranks. Shimano cranks have an end cap with a star shape interface; you adjust preload with that before tightening the crank arm pinch bolts.
