Why can thrust ball bearings not sustain radial loads? Why cylindrical roller bearings can not bear axial load?.
The thrust bearing retainer plate and two pieces of circular hole of the ball and the ball hole and shaft wear in the park, circular plate, steel ball track between two plate, shaft and the bearing seat of the top plate in the round two sides, in addition to the track groove, it is not binding the radial direction, so it cannot withstand the radial load.The radial bearing by the size of the two steel ring, steel ball size between steel ring, steel ring diameter fixed by a bearing seat, shaft mounted on a small steel ring, binding only in the radial direction and axial direction of the load is not binding, so it cannot withstand the axial diameter
Bearing bearing axial force or radial force is determined by the structure of the bearing, thrust ball bearings are also called plane bearings, which are mainly used to bear axial force; cylindrical roller bearings can bear radial forces and are not suitable to bear axial force.
(1) thrust bearings can not bear radial load:The models are different, and the loads are different. Some of them can carry axial loads in both directions. They can only be carried in one direction, such as 52000, which can bear bidirectional axial load(2) thrust ball bearings are designed to withstand thrust loads at high speedsConsisting of a washer shaped ring with a raceway for rolling the ball. Because the rings are cushion shaped, the thrust ball bearings are divided into two types: flat seat cushion type and self-aligning spherical cushion type. In addition, this kind of bearing can bear axial load, but can not bear radial load.(3) thrust ball bearing:The thrust ball bearing is composed of three parts: a race ring, an axle ring and a steel ball cage component. A shaft ring that fits with the shaft and is fitted with the housing.(4) species:According to the force of the situation, one-way thrust ball bearings and two-way thrust ball bearings. One way thrust ball bearing can bear one-way axial load. Two way thrust ball bearing can bear two-way axial loadWherein, the shaft ring is matched with the shaft. The bearing seat of the installation is spherical, with self-aligning performance, can reduce the influence of the installation error. Thrust ball bearings can not bear radial load, the limit speed is low.(5)1., there are two types of one-way and two-way2., in order to allow installation errors, both one-way and two-way, you can choose spherical, self-aligning, spherical cushion or ball surface, seat ring type.3. high quality steel - super clean steel with a maximum life span of 80%4., a high degree of grease technology, NSK lubricant technology, can prolong the life of grease and improve the performance of bearings5. high grade steel ball at high speed, quiet and smooth6. use the ring in the option, can allow installation error.
