Single row deep groove ball bearing, 1)

Single row deep groove ball bearings, it is the most commonly used hydraulic bearing. Most goods bearing inner and outer radius of curvature in the steel ball diameter of channel of 51. 5% - 539%. This kind of bearing assembly as shown in figure 1. 13 and figure 1. 14. Fill the ball between the inner and outer ring, installed in a supporting role is determined by the type: = 2122 type, Z is the count, D is the diameter of the ball, D. Is the ball center pitch diameter. Push the inner circle to the outer concentric position, and make the ball along the circumferential uniform distribution, and then in figure 1. 12 riveting cage or shown in figure 13. 18 a shows polymer cage to keep ball evenly distributed. Of deep groove ball bearings with high degree, and can accommodate the right ball bearing the pitch circle diameter and the count, so when the bearing materials, excellent performance, manufacturing precision, good lubrication and sealing when appropriate, has the very high bearing capacity. Although design of the bearing is used to bear radial load, but bearing in the radial and axial load, even only under the axial load state can work well. If the cage design is reasonable, deep groove ball bearings can withstand the small eccentric load ( Torque load) 。 If the bearing outer ring made spherical outside surface, the bearing has self regulating cardiac function, but not able to bear torque load.
