HBY Oil Resistant Excavator Seal Kit Polyurethane Material For Piston Cylinder

 
Cylinder HBY Seal Excavator Seal Kit Buffer Oil Seal For Piston Cylinder

Specification
 

 
 
Excavator Seal Kit Describe
 

HBY Piston Rod Seal, also known as the buffer seal ring, consists of a soft beige polyurethane seal and a hard black PA anti-extrusion ring added to the heel of the seal. In addition, HBY Piston Seal is used in conjunction with piston rod seals to absorb shock and fluctuating pressures under high loads, to isolate high-temperature liquids, and to improve seal durability.
Hydraulic cylinder seal kits are used to seal the gap between different parts of the hydraulic cylinder. The function of hydraulic cylinder seal kits is to prevent oil leakage, to assure the working pressure of the hydraulic system, to maintain its power. 

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.
