The inch series bearings are single row ball bearings available from .0400 through 1.500 inch bore sizes. The construction of these bearings enable them to carry moderate radial and thrust loads at low operating torque and provide high performance within a small envelope design. Inch series bearings are available in both stainless steel and chrome steel and come in open, sealed (2RS) and shielded (ZZ) configurations. They are also available flanged or unflanged.
