HGT 718 Series precision Angular Contact Ball Bearing. Their outer diameter and width increase in sequence for bearings with the same inner diameter. They often need to be assembled and installed with other bearings with axial loads opposite. Therefore. Angular contact ball bearings are combined with a double triple-combination, quadruple, or even quintuple combination.
HGT Precision Angular Contact Ball Bearing is classified into three different series: High-speed Angle Contact Ball Bearing (regular series), Super-high-speed Ceramic Ball Bearing, and High-speed Sealed Angle Contact Ball Bearing.
HGT also provides the mixed ceramic angle contact ball bearing for the high-speed, precise mechanic tool spindles and other high-speed precision spindles. Compared with other bearings with the same structure and dimensions, ceramic balls make the bearings electrically insulating, have higher speed, better performance, higher rigidity, and lower frictional coefficient, which vastly decreases the frictional heating of spindles and extends the service life of the main engine.
