The precision ball bearings produced by HGT can be divided into 4 series: 618 series、619 series、718 series、719 series. With the inner diameter range from 100mm to 950mm, and the precision is divided into P6, P5, P4 and P2. The bearings are available in open and sealed versions.
Spindle bearings have restricted tolerances. They are particularly suitable for bearing with very high requirements for guidance accuracy and speed capacity. They have proved highly suitable for the bearing of spindles in machine tools.
