EXAMPLES OF PACKING COMBINATIONS BY APPLICATIONS

Table PCA-2 lists examples by type of application. (2 of 2)



Type

Piston Seal

Rod Seal

Truck CraneWheel Crane

 


Expansion cylinder, Jack cylinder

pistondia7
The lip packing is used to prevent entry of sludge in oil with the long cylinder. OUH packing with good tracking ability is used also for the jack cylinder with large dynamic eccentricity.


Expansion cylinder, Rising cylinder

roddia7

Despite low pressure and infrequent impact pressure, IUH packing with back-up ring is used because of the ‘extrusion’ gap.


Truck CraneWheel Crane

 


Rising cylinder

pistondia8

Low friction SPGW packing is used because of rare occurence of stick-slip.


Jack cylinder

roddia8

Because of infrequent operation, low-temperature dust seal and IUH packing are used.


Forklift

Tilt cylinder

pistondia9

SPG packing without inversion and with small coefficient of friction and high durability is used


Tilt cylinder

roddia9

Because impact pressure requires no consideration, a small section packing is sufficient. For dust seal, DKBI with minimum oil leakage and high durability is used.


Forklift

Lift cylinder

pistondia10

Since it is a single motion and comparatively large eccentric cylinder, the lip packing with good tracking (OSI) is used.


Lift cylinder

roddia10

To minimize external leakage, dust seal with oil lip is used byt a drain must be provided.


Battery Forklift

Tilt cylinder

pistondia11

SPG packing with high durability and also for low temperature is used.


Tilt cylinder

roddia11

Low temperature packing (IUH) for rod seals and low temperature dust seals (DKB) with oil lip are used.


Battery Forklift

Lift cylinder

pistondia12

Low temperature lip packing (OUH) with good tracking is used.


Lift cylinder

roddia12

To minimize external leakage, low temperature dust seal with oil lip is used but a drain must be provided.
