⇄ Same-size Bearings & Reference Options

Standard reference: MS27643-8G. This size corresponds to the boundary dimensions of the MS27643 self-aligning double-row series. NLHB supplies it for industrial use; it is not supplied as an airworthiness-certified aerospace part.

The models below share the 12.7x42.863x25.4 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.
