NSK HPS™ Medium Spherical Roller Bearing of the outer ring raceway surface coincides with the bearing axis, they are self-aligning in a manner similar to that of self-aligning ball bearings.What is a Self-Aligning Bearing?Jan 13, 2016 — Paul Brda, Application Engineer, NSK Americas explains, “Whereas a ball bearing only has one raceway groove on both the inner and outer ring and 
Self Aligning Ball Bearings - NSKThis type of ball bearing is recommended when alignment of the shaft and housing is difficult and the shaft may flex. The outer ring has a spherical raceway Self-Aligning Ball Bearing - Open Type (NSK) - MISUMI[Features]-The inner ring, ball, and cage shaft have alignment properties that allow them to freely rotate around the center of the bearing.-Since the friction Self-Aligning Ball Bearings - NSK AmericasSelf-Aligning Ball Bearings are ideal when the alignment of the shaft and housing is problematic and the shaft may bend.
