Inpro Seal 1787-A-00381-0 Bearing Isolator — 2.375" ID / 3.500" OD. This Inpro Seal bearing isolator is a dedicated seal component for bearing assemblies, sized to fit a bore of 2.375 inches with an outer diameter of 3.500 inches. Bearing isolators are designed to seal around rotating shafts and bearings, creating a barrier between the bearing cavity and the surrounding environment and helping to preserve lubrication while minimizing contamination ingress in machinery. The 1787-A-00381-0 designation identifies a precise bore-to-outer-diameter specification that supports reliable fit and seal integrity in compatible equipment housings. As a purpose-built component from Inpro Seal, it is intended for installations where a 2.375-inch internal bore and 3.500-inch external diameter are required to maintain proper bearing isolation performance within the machine assembly.
