Self-Aligning Double Row Ball Bearings Self-Aligning Double Row Ball Bearings are designed to work in applications where severe misalignment exists whether from mounting or shaft deflection.  The concave raceway of the outer ring in combination with two rows of balls operate over a wide range of contact angles.  Furthermore it aligns itself correctly with the shaft and assembly without causing undue stress on the rest of the bearing assembly. Standard Self-Aligning Double Row Ball Bearings are produced with straight bores; however, tapered bores are available upon request.  Noteworthy is that the self-aligning ball bearing has the lowest friction of all rolling bearings, which enables it to run cooler even at high speeds.  Furthermore, the design allows for easy mounting and dismounting. Self-Aligning Double Row Ball Bearings come in three numeric series which represent the maximum specified degree of misalignment and loads: 1200 Series – Can be misaligned 2.5° 1300 Series – Can be misaligned 3.0° 2200 Series – Can be misaligned 2.5°  - wider than the 1200 Series 11200 Series – with wider inner ring Types available Pressed sheet steel cage, Nylon cage, Brass cage Nitrile rubber seal – sheet steel backed Self-aligning double row ball bearing catalog
