1. The outer ball bearing consists of a double-sided sealed outer spherical ball bearing and a cast (or steel stamped) bearing seat. The outer spherical ball bearing has the same internal structure as the deep groove ball bearing; however, the inner ring of such a bearing is wider than the outer ring. ring. The outer ring has a spherical outer surface; it is actively aligned with the concave spherical surface of the bearing seat. Usually there is a gap between the inner hole and the shaft of the bearing; the inner ring is fixed by a top wire; a heart, a sleeve or a sleeve. On the axis; and transform with the axis.
2. Thrust spherical roller bearings are used for shafts that accept axial loads. Warp joint load; but warp load shall not exceed 55% of axial load. Compared with other thrust roller bearings; such bearing has lower collision factor; higher speed; and has self-aligning ability. 29000 type bearing roller It is an asymmetrical spherical roller; it can reduce the relative sliding of the stick and the raceway during work; and the roller is long. The diameter is large; the number of rollers is large and the load capacity is large; the oil is usually smooth; the single low speed condition can be smoothed with grease.
3. The angular touch ball bearing has a higher limit speed; it can accept the meridional load and the axial load together; it can also accept the pure axial load; its axial load can be determined by the touch angle; and it increases with the increase of the touch angle. A touch ball bearing can only accept axial loads in one direction; when receiving a meridional load; it causes an additional axial force; it is necessary to apply a reverse load to the echo; thus; the bearings are usually used in pairs.
