Patent

CA 2190648

A sideframe pedestal jaw accommodates a bearing adapter which locks the adapter to the sideframe, thereby preventing it from all forms of movement within the pedestal jaw opening. Locking the bearing adapter forces the truck axles to remain at a right angle with respect to the sideframes. Maintaining this right angular relationship substantially curtails truck warpage, which induces wheel misalignment that leads to undesirable truck hunting and high speed instability.
