UC200 Insert ball bearing with wide inner ring and two set screws. Spherical OD and grease feeding groove. UC Series Insert Bearings has a set screw locking and is held in position on the shaft by two set screws which are directly on the extended end of the inner ring. UC200 Series Insert Ball Bearings are self-aligning for standard load capacity.Thrust spherical plain bearings are available with sliding contact surface combination steel/PTFE FRP which are suitable for single direction axial loads or combined axial and radial loads.They have low coefficient of friction and are relatively insensitive to contaminants. 

Insert bearings (SKF Y-bearings) are based on sealed deep groove ball bearings in the 62 and 63 series, but have a convex outer ring and in most cases an extended inner ring with a specific locking device, enabling quick and easy mounting onto the shaft.
