A-type single row angular contact ball bearings are different from C-type bearings in that A-type bearings have sufficient axial clearance and can generate sufficient surface tension to bear axial loads. Because of their unilateral load capability, the bearing must be assembled symmetrically with other bearings to set and maintain surface tension while minimizing axial movement when subjected to alternating axial loads. When mounted face-to-face, the bearings are assembled with 'zero distance' and the contact lines cross internally. By adjusting the relative length of the spacer between the inner and outer rings of the bearing, the clearance of the bearing can be adjusted. In general, the spacer rings are of the same length, and the bearings are matched with preset clearances. If the outer ring spacer is removed, the clearance can be adjusted with the gasket of the outer ring screw cap. The distinct characteristics of type A single row angular contact ball bearings depend on their mounting method. A certain bearing ring, usually the outer ring of the bearing, has a reduced shoulder on one side. Using the temperature difference between the inner and outer rings, the outer ring can be assembled with the inner hole, steel balls and ball bearings. This constitutes an inseparable bearing, which can bear more axial loads under the premise of bearing unilateral axial loads. When bearing axial load, the outer ring of the bearing can also be adjusted for small preload. This type of installation method makes A-type single row angular contact ball bearings have more steel balls than C-type bearings without mounting holes, and also has a very large surface tension, allowing it to have a higher axial load capacity. Because of their unilateral load capability, the bearing must be assembled symmetrically with other bearings to ensure surface tension while minimizing axial movement when subjected to alternating axial loads. The common installation methods of Type A single row angular contact ball bearings are face-to-face installation and back-to-back installation. When installed back-to-back, the contact line crosses outside the bearing, and the inner hole of the bearing is adjusted according to the sealing pad of the clamping ring, thereby adjusting the bearing clearance. To begin with, choose a gasket thick enough to allow the shaft to move relative to the bearing mount. Accurately measure all axial movement and pad thickness, subtract the sum of axial movement intensity and expected load. When the two bearings are symmetrically assembled, the internal clearance of the bearing is eliminated, and elastic deformation occurs between the steel ball and the dovetail guide rail, it is called a bearing with preload. Only when the torque is accurate can the rotation be stable! This article is from Co., Ltd., which has been manufacturing precision single row angular contact ball bearings for 37 years.
