1>Spherical roller bearings are double row, self-retaining units comprising solid outer rings with a concave raceway, solid inner rings and barrel rollers with cages. The inner rings with cylindrical or tapered bores.2>The symmetrical barrel rollers freely align themselves to the concave outer ring raceway. As a result, shaft deflections and misalignments of the bearing seats are compensated. 3>Many sizes of spherical roller bearings are supplied in X-life design. These bearings do not have a central rib on the inner ring so longer barrel rollers can be fitted; improved kinematics, optimized surfaces and even higher performance materials are possible. As a result, the bearings show a significant increase in the basic dynamic load rating and, under the same operating conditions, in the basic rating life. In certain applications, a smaller design of bearing arrangement can therefore be used if necessary. 4>Bearing series are from 21305 to 21322; 22205 to 22240; 23022 to 23052; 22308 to 22340.5>Material is Chrome steel (GC515).6>Type of Open, suffixes with K are available.
