BALL BEARING HOUSED UNITS A-62 TIMKEN BALL BEARING HOUSED UNIT CATALOG Download 3D Models and 2D Drawings at cad.timken.com SMN-S SERIES The SMN-S heavy-series construction permits its inner assembly to swivel in the outer aligning ring. Unrestricted self-alignment is achieved, allowing the inner ring to become square and true with the shaft and assembly. The external S-ring is uniquely ground and closely matched to its respective outer-bearing ring so that the S-ring of one bear- ing will not fit the outer ring of another bearing. This bearing has the basic 300-series load capacities. The bearings are not prelubricated. suggested shaft tolerances: 1 3 /16 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. Greater than 3 15 /16 in., consult your Timken engineer. To order, specify bearing number followed by "+ COl". Example: SMN103KS + COL.
