Lubrication method and application speed limit are confirmed per inquiry; no oil-speed value is derived from this number.
Standard reference: MS27648-23. This size corresponds to the boundary dimensions of the MS27648 externally self-aligning torque tube series. NLHB supplies it for industrial use; it is not supplied as an airworthiness-certified aerospace part.
The models below share the 36.525x60.325x11.1 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.
