ASTM A519 1045 Seamless OD50 WT4.0 +N Cold Drawn Precision Steel Tube +/-0.05mm OD for Linear Motion Shaft

ASTM A519 1045 OD50 WT4.0 Cold Drawn Precision Steel Tube +/-0.05mm OD

Product overview. This ASTM A519 grade 1045 precision steel tube is cold drawn to a +/-0.05mm od and supplied in +N delivery condition. Wall thickness is controlled within +/-5 percent and straightness within 0.3 mm per meter, so the tube seats cleanly in linear motion shaft assemblies without extra sizing, reaming or scrap loss on the line.

Key features

  • Tight dimensional window on OD, wall and bore keeps fit and roundness repeatable batch to batch
  • Ground and polished OD, produced on cold drawing lines with in-process laser gauging
  • No cracking under flaring, flattening and cold bending tests
  • Holding pressure without leakage after hydraulic proof test
  • Ends cut square and deburred, plastic caps fitted on both ends

Typical application

Linear Motion Shaft and similar assemblies that depend on stable bore and OD tolerance for sealing, guiding or fitting.

Quality documents
