Thrust angular contact ball bearing

Item name:Thrust angular contact ball bearing

Model: Example: 76020** series, 76030** series.

Description:Double direction angular contact thrust bearing is mainly applied on machine tools principal axis, while single direction angular contact thrust bearing is applied to support lead screw. Single direction angular contact thrust bearing belong to precision bearings. This type of bearing is mainly applied on high-speed rotating occasions and can be used a single or in pairs. The tolerance grade of double direction angular contact thrust bearing is special precision level.

Contact angle, the higher the axial load capacity. High precision and high-speed bearings usually take 15-degree contact angle. In the axial force, the contact angle will increase. Single row angular contact ball bearings can withstand axial load in one direction, the radial load will cause additional axial force. Shaft or housing and can only limit the axial displacement in one direction. If pairs of double security installed, make a pair bearing outer ring relative, that is, wide side face of wide and narrow side facing the narrow end. This can avoid additional axial force, but also in both directions so that the shaft or housing to limit axial clearance range.

Angular contact thrust ball bearings shown here were originally designed to support the rotary tables of drilling rigs but are also suitable for other applications where high load carrying capacity, high axial stiffness and low friction torque are important. In contrast to conventional thrust ball bearings, angular contact thrust ball bearings can accommodate radial loads in addition to axial loads and are able to operate at high speeds.

Single direction angular contact ball bearings
They are able to take up axial loads acting in one direction only. They are of separable type. The washers and ball and cage assembly can be mounted individually. In the main application, two bearings are adjusted against each other. The second bearing has to carry the weight of the drill when it is stationary and has a higher load carrying capacity than the first bearing.

Double direction angular contact thrust ball bearings
Here the upper bearing has the higher load carrying capacity and the smaller bearing in the opposite direction is combined with it to form a unit. These bearings have low height and can accommodate axial loads acting in both directions as well as moment loads. A single bearing can support rotating machine components in relation to stationary components.
