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.
With over two decades of engineering expertise, Huangshi Rviton Machinery Co.,Ltd has announced the expansion of its manufacturing capabilities to support global OEMs (Original Equipment Manufacturers) and aftermarket distributors. By leveraging state-of-the-art metallurgy and precision elastomer molding, the company delivers sealing solutions that significantly reduce downtime and extend the operational lifespan of heavy equipment

Advantages:
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.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.
