Travel final drive floating seal kits, also known as undercarriage part floating seals, are essential components in tracked vehicles like bulldozers and excavators. Excavator floating seals for travel gearbox provide effective sealing and protection for critical components in these rugged and demanding applications. Here's how floating seals are applied in tracked vehicles:

Bulldozer

Bulldozers are heavy construction machines used for pushing and moving large quantities of earth, rocks, and debris. Floating seals are commonly used in various components of bulldozers, including:

Track Rollers: Floating seals are installed in the track roller assemblies to prevent the entry of dirt, rocks, and debris into the roller bearings. This sealing helps maintain the integrity of the roller components, reducing wear and extending their service life.

Final Drives: Floating seals are also used in the final drives of bulldozers, which are critical for transmitting power from the engine to the tracks. These seals prevent the intrusion of contaminants, ensuring the proper functioning of the final drives and minimizing downtime.

Excavator

Excavators are versatile construction machines used for digging, trenching, and material handling in various construction and mining applications. Floating seals find application in several areas within excavators, including:

Track Drive Systems: Floating seals are used in the track drive systems of excavators to protect the components like track rollers, idlers, and sprockets from abrasive materials, preventing premature wear and ensuring smooth track movement.

Swing Gearbox: Floating seals are installed in the swing gearbox to seal against contaminants and maintain the lubrication, contributing to the reliability and performance of the excavator's swing function.

Travel Gearbox: Similar to the swing gearbox, floating seals are used in the travel gearbox to keep the gears and bearings protected from dust and debris, enhancing the durability of the gearbox.

In tracked vehicles like bulldozers and excavators, floating seals play a critical role in minimizing maintenance, reducing downtime, and extending the service life of essential components. Their ability to provide effective sealing in harsh and abrasive environments makes them indispensable for these heavy-duty applications.

Floating Seal Installing Tools

Installation tools and suitable installation procedure are highly recommended for series production and maintenance work. Installation process has a significant impact on seal performance, and diameters up to 1105mm installation tools are available for different mechanical face seals.

Before installation, arrange a cleaned seal, o-ring & housing and free from any mechanical damage and dent. Cleaning the seal using lint free wipe and ensure the seal face be thoroughly cleaned and no fine particles of dust should remain on it.

Place the o-ring on the metal seal ring at the bottom of the seal ring ramp and against the bottom of the seal ring ramp and against the retaining lip and then check it is properly sleeved. Make sure the o-rings are straight on the rim and not twist or squeeze.

Engage the lip of the installation tool between the gap of o-ring and seal face inside the circular guide way groove of the tool, and bring the edges of clamp close to each other.

Press the seal ring into the housing like a snap fastener, and press the fixture with even load on the guide plate. Small rings can be manually fixed, however for big rings apply even and gentle pressure around the rim of guide plate using wooden mallet.

Ensure that afterwards the housing face is parallel to the seal face, and o-rings must not undulate in the housing bore or kink and bulge out of the bore. Ensure the clearance between the seal ring housing bores with FUYOTE engineer.

Do not use sharp instruments in floating seal installation. Inappropriate tool cause irreversible damage of metal ring's sealing face. Because mechanical face seals are high precision product, especially the contact band, tools must be used in installation. We recommend the use of installation tools to ensure a proper installation of o-rings. If improperly installed, twist on o-rings might lead to uneven stress and creep down from the metal ring. Eventually cause early failure.

Keep the floating seal in the original packaging until installation, in case dust will get inside the seal before installation. Fine-finished seal faces of the metal seal rings and the o-rings need to be carefully protected from damage and contamination.

The seal housing which contact the rubber o-rings need to be clean and free from machining debris before installation. This should be done using a lint free wipe. Remove the foreign material from the o-rings, ramps and the lips of both seal rings.

Use alcohol to clean the parts instead of any other oil that leaves oil film or do not evaporates. Only use lint free wipes or cloths, and never use tissue paper or cotton waste.

O-rings cannot be used with blow holes or damages. And also cannot be twisted inside housing.

Do not use sharp tools to locate o-rings and hammer on sealing surface.

Check for sealing edge free from dirt, dust, and hair. Keep the sealing surface clean thoroughly before installation, and never allow sealing surface be dirty, keep it be cleaned well before assembly.

After compete the final assembly of the unit, make sure both seals are in the correct hosing position, due to high impact can scratch or break the seal components. A new set will have to be installed even the wear limit is not yet reached, when the seal set is taken apart in the course of repairs.

Advantages of heavy duty seals: easy to process housing bores and highly sealing reliability.

Primary Applications: off-road and tracked vehicles, conveyors and construction equipment, agricultural machinery and mining equipment.

Two metal sealing rings interact to create a sealing surface that is perpendicular to the axis. O-rings transfer pressure from the housing to these sealing rings, enabling one of the metal sealing rings to rotate with the housing while the other remains stationary. This results in relative motion between the two mechanical face seals.

The movement between these two face seals generates an oil film on the contact surface. This oil film is essential for effective sealing. As the parts rotate, the contacting surfaces form a contact band that typically ranges from 0.008 inches (0.2mm) to 0.02 inches (0.5mm) in width. This contact band retains the oil lubricant and resists the intrusion of foreign materials. Over time, as wear occurs, the contact band may shift inward. However, the elasticity of the O-ring compensates for this movement, ensuring that the mechanical face seals maintain their precise position and stability.

Key advantages of these seals include their resistance to wear and corrosion, resulting in a long service life and maintenance-free operation. They also exhibit exceptional sealing capabilities, effectively protecting against external contaminants like abrasive substances, moisture, chemicals, oil, and grease. Furthermore, these seals are self-centering, which helps compensate for shaft eccentricity or misalignment. Additionally, the presence of oil between the seal faces enables them to lubricate and cool, allowing for higher rotational speeds.
