A motor relationship and a table relationship
For each lift, the selector evaluates the exact motor and exact table separately. Named manufacturer compatibility establishes a supported relationship. A documented required collar, support adapter or modification produces a parts-or-work-required relationship. An explicit exclusion or documented plate-width mismatch rules out an ordinary supported fit.
The overall result follows the weakest evidence
A known unsupported relationship makes the overall combination unsupported. Otherwise an unknown relationship makes the combination unknown. Only when both sides are documented can a combination receive a documented-fit or parts-required result. A missing record is never treated as compatible.
Evidence is specific to the variant
A manufacturer manual takes priority over conflicting marketing text for installation requirements. A motor list can establish motor fit; it cannot prove table support. The INCRA Mast-R-Lift II, JessEm 02120 and JessEm 02121 remain distinct identities even though they share a family. Plate dimensions can identify a mismatch but cannot alone authorize installation.
The Rockler conflict
The Rockler Pro Lift product page contains inconsistent smaller-motor diameter text. We read both 52429 and 55803 manuals, page 4, and the 57022 collar product page. These establish the named motor-and-collar relationships used here. We do not generalize those relationships to unlisted motors by diameter.
Retailer receipts and buying links
Amazon Creators API receipts identify a listing, ASIN, photograph source and historical availability. They are not evidence of engineering compatibility. A bundle retains its bundle identity. The small-plate Rockler listing that could not be conclusively matched to 52429 has no buying link. We show no static offer prices or product performance scores.
