The Precision Angular Contact Ball Bearing can support the radial load and axial load simultaneously. It can work under a high rotational speed. The greater contact angle leads to higher axial loading capacity and lower limit speed. The bearing should be adjusted at the time of installation in order to achieve the required range of operating clearance or preload. If the user makes a request. HGT can also be supplied in groups.

Contact angle: 15 ° (code C), 25 ° (code AC) and 40 ° (code B)

he Precision Angular Contact Ball Bearing has 718 series bearing  and 719 series bearing. Both have the same inner radius, but the wideness and outer radius successively increase by degrees. Due to the unidirectional load carrying capacity, the bearing should be installed symmetrically in pairs with the other bearings to support the load in the opposite direction as well. Therefore, the Precision Angular Contact Ball Bearing usually can be installed in a set of two, three, four and even five.
The Precision Angular Contact Ball Bearing is classified by three different series: High-speed Angle Contact Ball Bearing (normal series), Super-high-speed Ceramic Ball Bearing and High-speed Sealed Angle Contact Ball Bearing.

We also provide 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 same structure and dimensions, it has higher speed, better performance, higher rigidity, and lower frictional coefficient, which largely decreases the frictional heating of spindles and extends the service life of the main engine.

1.Rate and speed in the catalogue is changed with the change of contact angle,please consult HGT technical department.
2.Our company can also produce diameter series 7 bearings(Super thin-section),please consult HGT technical department.
