The UnitedBuilt S19914MS outer bearing cap is a cast iron service component for M3ZRM and M3ZRMS pump bearing frames. It helps retain bearing grease and keep dirt and debris out of the bearing area.
S19914MS serves the outer bearing-cap position in both clockwise and counterclockwise arrangements, with either rope packing or a mechanical seal. The inner grease cap is a different part, S19033MS. Confirming which end of the bearing assembly needs service avoids confusing two caps that perform related roles.
