DF Floating Seal

The Fuyote design, where only one metal seal rotates, results in a leak-proof seal that requires no maintenance, offers exceptional longevity, and can accommodate various conditions such as vibrations, misalignment, eccentricity, assembly wear, and more. Below are the advantages of Fuyote products:

• The utilization of black seal faces reduces the risk of rusting and enhances the gripping capability of O-rings, eliminating O-ring sliding. For customers who prefer white seal faces, Fuyote provides anti-skid stripes to achieve the same effect.

• Cross-hatched grooves on the seal's contact bands ensure adequate oil flow and efficient heat management, allowing the seals to function effectively even in the most challenging industrial environments. This also addresses issues that rubber oil seals cannot resolve.

• All products feature end grinding surfaces crafted through a specialized process. This ensures spherical and angular stability among products within the same batch and prevents premature sealing failures caused by angular discrepancies between different products.

• Fuyote designs and manufactures O-rings specifically tailored to complement our products. These O-rings possess high elasticity, which minimizes wear and enhances product durability.

• The spherical cant design facilitates the alignment of the two mating boundary lines. This self-centering capability compensates for shaft eccentricity or misalignment, contributing to the overall effectiveness of the seal.

• When mechanical face seals are exposed to air for an extended period, they can undergo metamorphic changes. It's important to remove the seal package before installation. These seals are delicate and can break easily, so they should be handled with care and installed in a clean, dust-free environment.

• We strongly recommend the use of installation tools to ensure the proper installation of O-rings. Incorrect installation, which can result in twisted O-rings, may lead to uneven stress and cause them to slip off the metal ring, ultimately resulting in premature failure.

• Mechanical face seals are highly precise products, particularly the contact band. To avoid damage, refrain from using sharp tools during assembly and consider wearing gloves.

• Floating seals should be stored in a dark and cool place because O-rings are sensitive to temperature variations. They should be laid flat and not subjected to crushing during storage.

• The twisting of O-rings can result in uneven stress and cause them to slip down from the metal ring, leading to early failure. This is a critical concern that should be avoided.

Floating seals should not be employed in conditions where pressure and velocity parameters are inappropriate. Additionally, careful attention must be given to lubrication practices. Here are the guidelines:

• Recommended temperature range: -40 to 150 degrees Celsius.

• The working linear speed should not exceed a circumferential speed of up to 10 meters per second.

• Typically, floating seals can tolerate a maximum pressure of 0.3 megapascals (MPa).

• It is crucial to lubricate the seal at the sealing gaps. Preferably, oil lubrication should be used instead of grease lubrication.

• Maintain the oil level between the midpoint of the axis and two-thirds of the inside diameter of the seal. We recommend the use of SAE 80 and SAE 90 gearbox oils for lubrication purposes.
