ABSTRACT:
A method of securing a bearing either bushing, roller or ball bearing and a spacer or fitting into a soft non-ferrous material such as aluminum and materials of that hardness. A bearing of this invention containing an annular groove and adjacent forming shoulder or spacer, at least 1/2 a millimeter greater in diameter than the body of the bushing is inserted into a predrilled hole. A metal ring is formed in the annular groove as the shoulder is pressed into the parent material. This metal ring being a part of the parent material and being packed into the annular groove prevents retraction of the bearing or spacer during operation by its diameter being greater than the annular groove in the bearing. The material in the annular groove is of a lesser diameter than the body of the bearing and fitting and interfers with axial movement. The shoulder of the bearing or fitting has longitudinal grooves around its circumference. As the shoulder is embedded in the parent material the shape of these grooves are formed in the parent material. The formation of these shapes action prevents the bearing or spacer from rotating during operation. Either type of bearing, bushing, roller or ball may utilize this invention as can spacers or fittings of all sizes.
