Suitable for dozer loader track idler seals floating oil seals
SGU track chain oil seal (link oil seal)
Operating conditions:
Material: Polyurethane
Temperature: -35~100 ℃
Design Notes:
Track is an important component of walking construction machinery, widely used in construction, ports, mining and other occasions, facing harsh working conditions such as sand and sewage. In these harsh working conditions, the service life of the track depends on the sealing performance of the track chain pin.
In addition to sealing, waterproof, dustproof and other functions, as well as the compatibility of materials and grease, we also consider the situation of turning and unbalanced terrain in the design. The unique M-shaped design can fill gaps like a spring and maintain good sealing.

temperature
Generally, the storage temperature is required to be lower than 35 ℃ and away from fire sources. The seal may harden in low temperature environment, which may result in
Its deformation. Therefore, it should be placed in the environment of 20 ℃~30 ℃ for a period of time before use.
humidity
The appropriate relative humidity of the storage environment is 65%, and the air is kept free and ventilated.
illumination
Rubber seals shall be protected from direct sunlight and artificial strong light with high ultraviolet components.
Oxygen and ozone
Due to the serious damage of ozone to rubber seals, the storage room should avoid placing equipment that may produce electric sparks and discharges.
deformation
Rubber seals shall be stored in a natural state to avoid extrusion and stretching to avoid deformation.
Contact with liquid or semi-solid materials
Rubber seals shall avoid contact with liquid and semi-solid substances, especially solvents such as acid, oil and grease.
