CA Type Spherical Roller Bearings

CA Type Spherical Roller BearingsCA type Spherical Roller Bearing is a spherical roller bearing with a holding rib on the inner ring, a floating guide ring between the double-rows of rollers centered on the inner circle, and a brass double prong-type cage fixed on it – suffix. CA Spherical roller bearings are robust, self-restraining construction assemblies with double-rows of symmetrical spherical roller bearings. The axis of the roller rows is inclined at an angle to the turning axis of the bearing. The raceway in the outer ring is spherically formed so that the double-row roller assembly can adjust easily in case of misalignment or shaft deflections. The extremely high load capacity, angle-adjustable self-adjusting roller bearings are used where high impact radial dynamic forces have to be absorbed, and misalignment or more considerable shaft deflections are expected. They exist in many designs – from standard bearings to industry-specific specialized bearings.
