What the source establishesDimensional interchange

WorldWide Electric's HD Cast Iron competitive interchange table publishes HDRF206-H at 2.06 in center distance for C-face input / hollow-bore output. Manufacturers marked by WorldWide as not dimensionally interchangeable are intentionally excluded from Replacement Intelligence. Match ratio, motor frame, shaft/bore and application ratings before ordering.

Evidence meaning

The manufacturer publishes the two models in a dimensional-interchange table or equivalent dimensional comparison.

Grove Gear (new) HMQ220 and WorldWide Electric HDRF206-H are tied by the published source at Match installed ratio (5:1–60:1) · 2.06 in center distance.

Evidence boundary

Dimensional alignment does not by itself prove identical torque, thermal rating, service factor, ratio, accessories, or application suitability.
