Rexnord PT Select Series Spherical Roller Bearings – Nomenclature Excerpt from Rexnord Bearings Catalog #BR101-100EN. . Where outer seal cannot be applied or in the case of strong contamination "multi-barrier" seal should be used. When loads are heavy, alignment of housings difficult, and shaft deflections are excessive, the spherical roller bearings assures best service life results. Typically these bearings support a rotating shaft in the bore of the inner ring that may be misaligned in respect to the outer ring. A spherical roller bearing is a rolling-element bearing that permits rotation with low friction, and permits angular misalignment. For spherical roller bearing X and Y are variable on two different conditions: X = 1, Y = Y1.
