摘要：

It is shown that it is possible to raise the rate and to extend the range of the production of small bearing tubes. This results from an advanced flow-sheet which involves screw- and lengthwise rolling of a billet less than 60 mm in diameter followed by single-pass or multipass plug and/or without mandrel drawing. These processes were used to manufacture a commercial lot of bearing tubes of a steel ShKh15 23×45 mm, 31×4.5 mm in size, etc.
