Request a written material designation, batch-linked documents, a manufacturing statement, and relevant test evidence. Keep fitment, provenance, sample results, and batch acceptance separate.
Similar dimensions alone do not confirm fitment, load performance, part-number status or batch quality; this article explains the evidence needed before acceptance.
A direct procurement guide: separate material designation, batch-linked documents, manufacturing statements, and test evidence before accepting a supplier's same-material claim.
Similar track roller dimensions alone do not establish drawing revision, reference surfaces, tolerances, fitment or batch acceptance for a SANY excavator. This article explains the procurement evidence needed before acceptance.
Similar measured dimensions may be a useful first check, but they do not prove drawing revision, tolerance conformance, load performance, fitment, or batch acceptance for road and quarry use.
