Excavator Seal Kit Describe
Precautions
1. Clean the installation location;
2. Remove the burrs during the installation movement of the seal;
3. Apply lubricant on the seals;
4. Protect the sealing surface from damage;
5. Recheck to confirm that the size of the seal is correct;
6. Use corresponding tools to install the seals that need to be
deformed and installed.
Features
1.It is applied to hydraulic system from middle load to high load.
2.antiextrusion characteristics is improved greatly.Long service
life
3.Good Shape stability ,high wear resistance,good chemical
stability
4.Excellent sliding performance,no creeping phenomenon
Do not open the seal package if unnecessary, otherwise the dust
will stick to the seal or scratch it.
Store in cool place, not on sunlight place. UV and moisture will
accelerate the deterioration of rubber and plastics and dimensional
changes
Carefully pack, store unpackaged product, do not glue or put into
impurities, keep the original state. Keep the Nylon seal package
close to prevent moisture cause dimensional changes
Do not put seals near heat sources, such as boilers, stoves.
Otherwise heat will accelerate the aging of seals
Do not put seals near the motor and other place where produces
ozone
Do not use a needle, wire, rope hang seals, otherwise, would cause
the seal deformation, damage the lip
Sometimes, there are color change or white powder on the seal
surface (frost phenomenon), this will not affect the performance of
the seal
Application
(1) Full of elasticity and resilience;
(2) Appropriate mechanical strength, including expansion strength, elongation and tear resistance.
(3) The performance is stable, it is not easy to swell in the medium, and the thermal shrinkage effect (Joule effect) is small.
(4) It is easy to process and shape, and can maintain precise dimensions.
(5) Does not corrode the contact surface, does not pollute the medium, etc.
The most suitable and commonly used material to meet the above requirements is rubber, so the sealing ring is mostly made of rubber. There are many types of rubber, and new types of rubber are constantly appearing. When designing and selecting, one should understand the characteristics of various rubbers and choose them reasonably.
