Self-aligning roller bearings
Self-aligning roller bearing has two rows of spherical rollers, the outer race is provided with a common concave spherical raceway, the inner race with two concave spherical raceways that form an angle with the bearing axis. The curvature center of the outer raceway is consistent with the bearing center. The self-aligning roller bearing is self-adjusted, and it is not affected by non-centering or shaft deformation flexure of shaft and bearing block, so it can compensate the concentricity error caused by these reasons. Except subject to radial load, this type of bearing can also withstand small bidirectional axial loads. The load capacity is large, and the bearing is provided with preferable shock resistant capacity. It is one of the bearings most widely used in mechanical industry.
1.The ones with cylindrical bore
2.The ones with conical bore
Self-aligning roller bearings are widely applied to paper-making, deceleration device, railway vehicle axle, rolling mill, roller gearbox,crusher, vibrating screen, printingmachinery, woodworking machinery and various industrial reducers.
1.Low friction and high rolling speed
