Self Aligning Ball Bearing Tapered Bore (C3)

• Tapered bore.
• C3, clearance greater than normal.
• The inner ring of this type of bearing has two raceways and the outer ring has a single spherical raceway with its center of curvature coincident with the bearing axis.
• Therefore, the axis of the inner ring, balls, and cage can deflect to some extent around the bearing center.
• Consequently, minor angular misalignment of the shaft and housing caused by the machining or mounting error is automatically corrected.
• This type of bearing often has a tapered bore for mounting using an adapter sleeve.

About Self Aligning Ball Bearing

• The outer ring has a spherical raceway and its center of curvature coincides with that of the bearing; therefore, the axis of the inner ring, balls, and cage can deflect to some extent around the bearing center.
• This type is recommended when the alignment of the shaft and housing is difficult and when the shaft may bend.
• Since the contact angle is small, the axial load capacity is low.
• Pressed steel cages are usually used.
