Spherical roller bearings installed
Spherical roller bearings have two raceways in the inner and outer ring raceways between spherical, the assembly of a drum-shaped roller bearings. Outer ring raceway curvature center and bearing center line, so has the same self-aligning ball bearing self-aligning feature. In the shaft, deflection occurs when the shell, you can automatically adjust the direction of axial load and two loads. Radial load capacity, suitable for heavy load, impact load conditions. Inner diameter is tapered bore bearings can be installed directly. Or use the sleeve, remove tube installed in the cylinder axis. Pressed steel cage with cage, polyamide forming cage and copper alloy machined cage. For the self-aligning bearings, the bearings in the shaft into the box with the shaft hole, 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 are generally mechanical or hydraulic pressure into the method for installation. For the separable type bearings, inner and outer rings can be installed separately, thus simplifying the installation process, especially when the rings are required, especially when the interference fit. Already in place in the inner shaft into the outer ring of the bearing box included, must pay attention to see whether the right of the inside and outside the ring, to avoid scratching the bearing raceways and rolling elements. If the cylindrical and needle roller bearings without flanges or side of the inner wall of the inner flange, the recommended installation sleeve. Sleeve diameter inner ring raceway diameter should be equal to F, machining tolerances to be d10. Needle roller bearings is best installed using the mandrel.
