The ferrule on the shaft is called the shaft ring; the ferrule on the ferrule is called the race; the two-way bearing is used on the shaft. The thrust ball bearing is a detachable bearing; it can only bear the load. One-way bearings can only accept axial loads in one direction; two-way bearings can accept alternating axial loads in two directions. Thrust ball bearings need to be axially pre-tensioned during operation. They are primarily suitable for machine tool spindles, automotive clutches. , reducer, etc.. Two-way thrust angle touch ball bearings are suitable for machine tool spindles; one-way thrust angle touch ball bearings are suitable for screw support. Thrust ball bearings can not constrain the radial movement of shafts or shells; Axial movement; thus; such bearings are usually used in conjunction with deep groove ball bearings; the axis of the shaft and the housing bore must be concentric; otherwise the bearing will be prematurely damaged due to stress gathering. To eliminate this Phenomenon; a radial clearance of 0. 5 to 1 mm may be left between the outer diameter of the race and the hole of the casing. The axial center line and the bearing surface of the casing shall be straight; the axis shall not be skewed and deflected; otherwise Because the load spreading premature bearing damage caused uneven to eliminate skew bearing axis; may be an elastic pad material on the support surface of the seat ring; oil such as rubber, leather, and the like; or use with spherical seat thrust ball bearings.
Thrust ball bearings are usually selected from steel plate stamping frames, when the outer diameter is ≥ 250mm;
