Spherical roller bearings in the two groove of the inner ring and the outer ring raceways between spherical, assembly of a drum shaped roller bearings. The outer ring raceway surface curvature center and bearing center line, so with automatic self-aligning ball bearing the same tune of heart function. Deflection appeared on theshaft, the shell, the axial load can automatically adjust load and two directions. Radial load capacity, suitable for heavy load, impact load conditions. Inner diameter is tapered bore bearings, can be directly installed. Or use the sleeve, remove tube installed in the cylinder axis. The holder to use steel stamping cage, polyamide forming cage and copper alloy machined cage.

For the self-aligning bearings, the bearing arranged in the box body axes hole zone axis, use the middle ring to prevent installation of tilt and rotate the outer ring. It should be remembered that some dimensions of self-aligning ball bearing ball bearing protruding from the side, so the middle ring should be installed recessed to prevent damage to the ball. A large number of bearings generally use mechanical or hydraulicpressure into the method for installation.

For the separable type bearings, the inner ring and the outer ring can be installed separately, thus simplifying the installation process, especially when the rings are required of interference fit. In the bearing box has been installed in place of the inner ring shaft into the already contains the outer ring of the inner ring and the outer ring,must pay attention to see whether the right of the road, in order to avoid the rolling member rolling bearing and scratch. If the cylindrical and needle roller bearingswithout flanges flange inner ring or side edge of the inner ring of the flange, the recommended installation sleeve. The sleeve should be equal to the outer diameter ofthe inner ring raceway diameter F, standard machining tolerance shall be d10.Stamping outer ring needle roller bearing is best to use a core shaft installation.
