Self-aligning Roller Bearing

Self-aligning roller bearings with two rollers, mainly bear radial load, but also can withstand the axial load any direction. High radial load capacity, especially suitable for the work overload or vibration loads, but can not afford pure axial load. Kind of bearing outer ring raceway is spherical, so the good performance of aligning, can compensate concentricity error.
Two symmetrical spherical rollers and a common spherical outer raceway, inner ring raceway two bearing axis is tilted at an angle, aligning different heart bent or installed when the axis of the force when still bearing the normal use. Mind with the bearing dimension series generally permissible aligning angle is 1 to 2.5 degrees, the load bearing capacity of the type, in addition to be able to withstand the radial load bearing can withstand bidirectional axial load, and has good impact resistance, in general tone self-aligning roller bearings allow lower speed.
Self-aligning roller bearings by roller-sectional shape is divided into symmetrical spherical roller and non-symmetrical spherical roller two different structures, asymmetric self-aligning roller bearings are early products, mainly for the host repair services, new design host is rarely chosen symmetrically shaped self-aligning roller bearings, the internal structure has been completely improved design and parameters optimization with the early production self-aligning roller bearings, able to withstand greater axial loads, these bearings run lower temperature, it can be adapted to the requirements of higher speed, according to the presence or absence of ribs and the inner ring with cage can be divided into two kinds of C-type CA, the characteristics of the C-type bearings without inner ring ribs and using steel stamping cage, CA type bearing characteristics as compared to the inner ring on both sides ribs and machined solid cage in order to improve the lubrication, can provide users with the outer ring with an annular groove and three hole-aligning roller bearings, bearing rear Code / W33 can supply self-aligning roller bearings with inner ring hole, according to the user's requirements, and also provide within the hole in order to facilitate customer handling and replacement of bearings, with taper-aligning roller bearings cone taper 1:12 after set, code-named K can also be said that, in order to adapt to the specific user requirements bearing bore taper 1:30, and subsequently set, code-named K30 with tapered bore bearings can be used to lock nut bearing directly mounted on a tapered journal, and can also use an adapter sleeve or withdrawal sleeve mounted in a cylindrical journal bearing. In order to prevent harmful slip due to the centrifugal effect between the raceway and roller bearings in high-speed operation, the bearings should bear a certain minimum radial load.
