Roles of Cylinder Seal
1 Preventing oil leak
The cylinder seal prevents oil leakage of a cylinder. Oil leakage through a deteriorated seal may
cause various troubles.
2 Preventing impurity intrusion
The cylinder seal prevents the intrusion of dust and moisture from the outside. Intrusion of
impurities into the hydraulic line may adversely affect other hydraulic devices including pumps,
cylinders, and motors by causing scoring, abnormal wear and other problems.
3 Maintenance of pressure
The cylinder seal maintains pressure inside a cylinder. Low pressure inside a cylinder caused by a
damaged seal lowers the front speed and digging force.
When seal deterioration or oil leakage is detected, early replacement of the seal isrecommended.
