Spherical roller bearings

Spherical roller bearings have two raceways between the inner and outer ring raceway is spherical, equipped with a drum-shaped roller bearings. The outer ring raceway curvature center and bearing center line, so has the same self-aligning ball bearing self-aligning feature. When the shaft, shell deflection occurs, you can automatically adjust load and axial load in two directions. Radial load capacity, for a heavy load, impact load conditions. Inner diameter is tapered bore bearings can be installed directly. Or using an adapter sleeve, remove tube installed in the cylinder axis. Cage with steel stamping cage, forming polyamide cage and copper alloy machined cage.
For the self-aligning bearing, in the bearing housing bore the loading zone axis, using an intermediate mounting ring prevents tilting and rotating the outer ring. It should be remembered that some dimensions of self-aligning ball bearing ball bearing protruding from the side, so the middle of the ring should be installed recessed to prevent damage to the ball. self-aligning roller bearing A large number of bearings are generally used mechanical or hydraulic press for the installation method.
For the separable type bearings, the inner ring and outer ring can be installed separately, thus simplifying the mounting process, especially when the inner and outer rings are especially required interference fit. In the inner shaft has been installed in place of the outer ring of the bearing box load included, must pay attention to see on the inner and outer rings are correct to avoid scratching the bearing raceways and rolling elements. If the cylindrical and needle roller bearings with inner ring without flange or side wall of the inner flange edge has recommended installation sleeve. The outer diameter of the sleeve should be equal to the diameter of the inner ring raceway F, standard machining tolerances should d10. needle roller bearings is best to use a mandrel installation. Different types of spherical roller bearings:
