High performance self-aligning ball bearing 1203 series

high performance self-aligning ball bearing 1203 series

Self-aligning ball bearing has two rows of balls and a common sphered raceway in the outer ring.The bearings are consequently self-aligning and insensitive to shaft deflections and angular misalignment of the shaft relative to the housing. Additionally, self-aligning ball bearings generate less friction than any other type of rolling bearing, which enables them to run cooler even at high speeds.This type of ball bearing is recommended when alignment of the shaft and housing is difficult and the shaft may flex.he 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. Pressed steel cages are usually used. Since the contact angle is small, the axial load capacity is low. The permissible dynamic misalignment is approximately 0.07 to 0.12 radian (4 to 7 degrees) under normal loads.

Characteristics of Self Aligning Ball Bearings

• The self-aligning ball bearing has two rows of balls.
• A common concave sphered raceway in the outer ring.
• The center of whose curvature meets that of the bearing itself, so that the inner ring, balls and cage continue to rotate.
• The self-aligning ball bearing with a tapered bore can be easily fitted on the shaft with an adapter assembly.
• Have the lowest friction of all rolling bearings.
• Run cooler even at high speeds.
• Easy mounting and dismounting.
• The permissible operating speed is not dependent on the common criteria like heat generation or cage stability and strength.

Applications of Self Aligning Ball Bearings

• Self-aligning ball bearings are used for commercial ground shafting applications.
• Since axial load capacity is limited, self-aligning ball bearings are not suitable for applications with heavy axial loads.
• Furthermore, if an adapter is used on the tapered bore of the inner diameter, installation and disassembly are much simpler and for this reason adapters are often used on the equipment with drive shafts.
