Match a protection claim to the assembly it covers
A bearing seal or shield is one feature of an execution.
A complete unit also has interfaces involving the shaft, housing, covers, fittings and other components. Manufacturer sealing guidance treats contamination exclusion as an assembly and operating-condition question. The word “sealed” therefore cannot establish resistance to every water exposure, cleaning chemical or pressure-washing arrangement. A claim about the internal bearing must not be extended automatically to the entire unit. Ask which exact product and test or specification supports the required exposure, and keep that evidence separate from a general catalog description of the bearing's seal type.
