Drawing-based manufacture and technical review

For drawing-based manufacture, check the mainshaft body and protective sleeve separately. Confirm journals, tapers, threads, fits, material, forging grain flow, heat treatment, mechanical properties, non-destructive testing, surface finish and straightness.

Required Ordering / RFQ Information

  • OEM, complete model, serial number and assembly or part number;
  • Latest drawing revision, dimensions, unit weight, critical tolerances and assembly interfaces;
  • Current material, heat treatment, hardness, mechanical properties and nondestructive testing requirements;
  • Failure photos, wear measurements, crack locations, current service life and target life;
  • Fit with adjacent parts, fastening, lubrication, sealing and assembly/disassembly requirements.
Parts or assemblies with the same name can differ between brands, series and production periods. Confirm the complete model, drawing number and revision before manufacture.
