11505 ETN9 Spherical ball bearing

Self-aligning ball bearings, with 1:16 ratio tapered bore, have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. They are insensitive to angular misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection. The tapered bore facilitates ease of mounting via the included adapter sleeve.
