| Face finish | ≤ Ra0.015μm |
| Pressure | ≤ 0.3MPa |
| Forged/Casting line speed | 2m / s & 3m / s |
| Hardness | 58 - 62 HRC |
| Temperature | -100 ~ 200 °C |
- The rubber o ring
| Shore hardness | 60 ° ~ 65 ° |

Method of installation:
1. Using specialized tools installation: The pressure will apply to
the O-ring directly. As shown, the special tool is mounted between
the metal floating ring and the rubber ring, toward the seat hole,
the rubber ring is evenly pressed into the hole.
2. Other installation methods: One auxiliary O-ring is fixed
between the conical ring surface of the floating oil seal and
sealing O-ring (as shown). The ring of the floating oil seal is
applied uniformly by pressure and the auxiliary O-ring braces the
sealing O-ring to ensure the other correct mounting positions.
