⇄ Same-size Bearings & Reference Options

Standard reference: MS27641-8R. This size corresponds to the boundary dimensions of the MS27641 medium-duty deep-groove radial series. NLHB supplies it for industrial use; it is not supplied as an airworthiness-certified aerospace part.

The models below share the 12.7x28.575x9.525 mm boundary dimensions. Matching d/D/B alone does not prove interchangeability; verify seals, clearance, ring features, load ratings, fits, and application conditions before replacement.
