In the highly demanding world of heavy construction, mining, and agricultural machinery, mechanical integrity is paramount. Dust, mud, water, and extreme temperatures constantly threaten the life cycle of undercarriage systems and gearboxes. To combat these challenges, Huangshi Rviton Machinery Co., Ltd., a premier Chinese manufacturer, has announced a series of breakthroughs in the production and global distribution of its high-performance floating seal technologies.
In modern construction, mining, and agricultural machinery, mechanical face seals (also known as lifetime seals or duo-cone seals) are vital for protecting rotary bearings from external contaminants while retaining lubrication. Huangshi Rviton Machinery Co., Ltd. has established itself at the forefront of this niche sector, leveraging advanced metallurgy and elastomer chemistry to deliver world-class products.
Heavy machinery operates in some of the most unforgiving environments on Earth. From dust-choked mining pits in Western Australia to freezing construction sites in Northern Europe, undercarriage systems are constantly subjected to abrasive grit, mud, water, and extreme pressures. In these environments, the integrity of a machine’s undercarriage hinges entirely on the performance of its sealing system.
The metal rings:
| Surface finish / Roughness | ≤ Ra0.2μm |
| Face finish | ≤ Ra0.015μm |
| Pressure | ≤ 0.3MPa |
| Forged line speed | 2m / s |
| Casting line speed | 3m / s |
|
Temperature
|
-100 ~ 200 °C |
The rubber rings:
| Shore hardness | 60 ° ~ 65 ° |
| Minimum tensile strength | 11MPa |
| Minimum elongation at break | 300% |
| Flexible change | ± 5 ° |
| permanent deformation | ≤ 12% |
The advantages of our product:
1.Coexistence of high quality and competitive prices
2.Long service life
3.Easy to install
4.High yield
5.Good performance
Method of installation:
1.Usingspecialized tools installation: The pressure will apply to the O-ringdirectly. As shown, the special tool is mounted between the metalfloating ring and the rubber ring, toward the seat hole, the rubber ringis evenly pressed into the hole.
