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.

Product Show

The seal group consists of metal rings and rubber rings.

Metal rings:

Surface finish / Coarseness Μ Ra 0.2 μm
Face End ≤ Ra 0.015 μm
Pressure A 0.3MPa
Forged line speed 2 m / From
Casting line speed 3 m / From
Temperature
 -100 ~ 200 ° C

 

Rubber rings:

Set aside the difficulty 60 ° ~ 65 ° 
The minimum Tensile strength  11MPa
The minimum elongation at break  300%
Flexible Change  ± 5 °
Permanent deformation ≤ 12%


Advantages of our product:

1. Survival of high quality and competitive prices

2. Have long service life

3. Easy to install

4. High yield

5. Good performance

Method of installation:

1.Usingspecialized equipment installation: The pressure will apply to the O-ringdirectly. As shown, the special tool is placed between the metal hole ring and the rubber ring, towards the seat hole, the rubber ring is pressed evenly into the hole.

                                              
2. Other methods: An auxiliary O-ring is fixed between the sealing surface of the floating oil seal and the C-ring (as shown). The floating oil seal ring is applied equally by pressure and auxiliary O-ring braces. Sealing the O-ring to ensure other mounting positions.

Also there are a lot of specifications which I list just a small part. Enjoy me for asking if you haven't found what you want. Thanks!
