The Self Aligning Ball Bearings from DCDC are double row, self-continuing units that comprise of solid outer rings with a concave race way, inner rings and a cylinder or tapered bore with a ball and cage assemblies. The ball bearings are available in both open and sealed versions. This kind of ball bearing is suggested when the alignment of the shaft and the housing is difficult and the shaft might bend. The outer ring of this ball bearing has a spherical raceway and the center of the curvature coincides with that of the bearing.
The ball bearings are made of high quality steel, advance grease technology to extend life and performance, high grade performance for quiet and smooth operations, sealed versions available and super finished raceways.
