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
