⇄ Same-size Bearings & Reference Options

Standard reference: MS27644-5. This size corresponds to the boundary dimensions of the MS27644 double-row radial series. NLHB supplies it for industrial use; it is not supplied as an airworthiness-certified aerospace part.

The models below share the 7.938x31.75x18.923 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.
