Self Aligning Ball Bearings: This bearing series has two rows of balls running on the same spherical outer raceway, this makes the bearing self aligning, self centering and insensitive to angular misalignment. They are particularly suited to applications where considerable shaft deflections are anticipated. Self aligning ball bearings have the lowest rolling friction of all rolling bearings and are the coolest running bearing type even at high speeds Benefits: Tolerates misalignment, cool running, self centering Brand / Quality: Major Brand - High Quality Inside Diameter: 8mm Outside Diameter: 22mm Width: 7mm Seals / Shields: None Clearance: * Standard            d      D     B      Cr    Cor       weight                                                         126    6    19    6    2.53    0.475    0.008 127    7    19    6    2.75    0.6     0.010 108    8    22    7    2.75    0.6     0.013 129    9    22    7    4.15    0.895    0.021 1200    10    26    8    5.55    1.19    0.033 1201    12    30    9    5.7    1.27    0.039 1202    15    35    11    5.85    2.05    0.051 1203    17    40    12    6.2    2.45    0.072 1204    20    47    14    7.8    3.25    0.1185 1205    25    52    15    9.5    4.1    0.144 1206    30    62    16    12.3    5.9    0.226 1207    35    72    17    12.4    6.75    0.318 1208    40    80    18    15    8.7    0.411
