Study Notes

Branding Details on Wheels and Axles

  • Wheel Details: Stamped or marked on the outer face of the wheel rim (rough or finished). For LHB coaches, stamping on the outer hub face. Additional markings (S.No. 1-4) on the outer hub fillet.
  • Wheel Centre Details: Cold stamped or electrically etched on outer hub face at specific locations.
  • Axle Details: Stamped or electrically etched on both ends (5 mm letters for rough/finished axles; 10 mm if forged).
  • Assembly Details: Marked on the outer face of the wheel/wheel centre hub (10 mm letters).
  • PCD of Stamping: Different wheel types have different PCD (Pitch Circle Diameter) for stamping on rims. Example: WTAC3-0-2-301, T-0-2-622 for coaching wheels have 788mm PCD.
  • Additional Marking (X): Required for LHB coach wheels.
  • Mandatory Markings: All specified markings on wheels, wheel centers, and axles are mandatory. Locations are indicated.

Outer Ring Marking

  • Reconditioning/Remanufacturing: "R" encircled marking must be on the inner diameter of the outer ring (straight portion).
  • Caution: Avoid damaging the raceways when marking.
  • Marking Method: Suitable scribing tool. Electric etching or steel stamping prohibited.

Marking of Overhauling Particulars on Backing Ring of CTRB

  • Location: Stamping on backing ring of CTRB.
  • Size: 20 mm letters and numbers.
  • Content: Workshop code, month, and year.
  • Legibility: Stamping must be legible.

Marking for Ultrasonic Testing of Axles

  • Location: Inner hub fillet.
  • Method: Cold stamping.
  • Content: Railway workshop code, month, year of test (initial of examiner).
