High
durability SPG is used. Two WR are used to prevent scoring
between the piston head and the cylinder tube that can
be caused by high lateral load typical for such operating
condition. |

|
|
Parking and dust seal of nitrile
rubber are used.

OUHR with stick slip proof characteristics
is used considering the operating condition that requires
to keep working pressure for a long time. O5ZF having
small friction resistance is used for the material of
wear ring. |

|
 |
HBTS is used to prevent stick slip.

SPGW is used since such operating conditions mainly performed
under high pressure require the durability. This packing
has also excellent durability for the operations requiring
extremely short strokes. |
| |
|
 |
HBTS is used for buffer ring to
reduce high impact pressure. Please add a drain to improve
durability.

Fabric reinforced rubber V packing
are used because in such operating conditions, fluids
with poor lubricity, such as water and agricultural chemicals
are handled and frequency of operation is high. When pressure
and frequency of operation are low, rubber V packing can
be used. |
