About Quality
1. Roller Body: Material is 40Mn2 ---hard wearing,
so, that can extend the roller's service life.
2. Bushing: 100% fine cooper Bushing,
instead of duplex metal(Iron and Cooper).
The thickness of bushing is 6mm-10mm.
3. Pin: The material is 42Cr
4. Floating seals: the size of Floating seals
must 100% match the roller.
If not, the oil will spilling.
5. The most important process is Hardening and Tempering
if the rollers are not undere Hardening and tempering,
the Mechanical Properties, Yield Strength and Tensile
Strength will not be good, the roller will be slip easily.
6. 7 kinds of Quality Inspection:
Chemical Composition
Mechanical Properties after HT
Metallography/Microstructure
Dimensional Accuracy
NDT Examination/LPI or MPI
NDT Examination/UT
Cutting / Sectioning
Process of Track Roller
