In babbitt bearings, a metallurgical bond is superior to a mechanical bond for it eliminates the need for anchor grooves which have been known to trap air and oxides.
In centrifugal casting, the pre-tinned pre-heated bearing shell and its fixtures are placed between two faceplates of a Model CB Machine and clamped securely in place. The bearing is rotated about its own axis at a pre-determined speed. The speed of rotation is dependent on the size of the bore you wish to produce and the type of alloy. The speed of rotation is based on the G force applied to the molten babbitt being cast.
