Exact selected igus TW-04-09 article family, catalog mass, installed envelope, four-hole M2 mounting pattern, rail-seat dimensions, construction, and tightening limit. The solid is reconstructed from the manufacturer drawing rather than downloaded manufacturer CAD; hidden adjusters, proprietary pad geometry, running clearances, and surface radii are not inferred. Preload, friction, alignment, fastener retention, load capacity, wear, contamination response, and Belfry suitability remain physically unvalidated.
