Hydraulic cylinder tube advantages:
1. high surface roughness, the roughness Ra ≤ about 0.08μm.
2. oval-degree ≤ 0.01mm.
3. to improve the surface hardness, making the elimination of stress and deformation, hardness HV ≥ 4 °
4. processing residual stress layer, improve fatigue strength increased by 30%.
5. improve quality, reduce wear and extend component life, and reduce processing costs of parts instead.
