Spherical Roller BearingsSpherical roller bearings are intended for accommodation of radial load, but they simultaneously can accommodate axial load, acting in both directions and not exceeding 25% of unused permissible value of radial load.
They are self-aligning bearings and they are able to compensate considerable misalignment, caused by shaft deflection under load and technical errors during the machining of seatings, or unit assembling. Bearings performance is kept when misalignment of the inner ring axes relative to the outer ring axes is about two degrees. They fixshaft in both sides of axial direction within existing axial clearances. Bearings are made with asymmetric and symmetric rollers with cylindrical and tapered bore of inner ring, with adapter and withdrawal sleeves. Bearings are used in support of units and mechanisms, where large radial loads take place and where misalignment of the seatings is inevitable. They are applied in powerful pumps, fans, gearboxes, as well as in sawing machines, propeller shafts and rolling mills.
