A-41 BALL BEARING HOUSED UNITS

SM INDUSTRIAL SERIES A AND B TYPES/MUA-B INSERTS

(1)

Standard SM series A and B have the same ring tolerances and corner radii as equivalent 200-series single-row radial ball bearings. Type A has cylindrical outside diameters; type B has spherical outside diameters. The letter B appears on the outer ring only. The bearings are not prelubricated. suggested shaft tolerances:

1

/2 in. - 1

15

/16 in., nominal to -0.013 mm, -0.0005 in.; 2 in. - 3

15

/16 in., nominal to -0.025 mm, -0.0010 in. To order, specify bearing number followed by "+ COl". Example: SM1207KB + COL.
