Product Description:
- 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.
- There are regularly three cylinders for the excavator, boom
cylinder, arm cylinder, bucket cylinder.
- Boom cylinder is the one (or the two) near the cabin. Usually,
there is one piece boom cylinder for the small excavator under
10-tun; the bigger excavator's two pieces boom cylinders. But there
is an exception too when the driver will remove one piece for a
special purpose, say at some particular working place, it is
convenient to work by one cylinder. Soft remind: all refit job

The Role of Each Part
A. Fitting part: While fixing the oil seal to the cavity hole, the fitting part
plays the role of preventing fluid leakage and intrusion from the
contact surface between the outer peripheral surface of the oil
seal and the inner surface of the cavity. In addition, the metal
skeleton plays the role of fixing the oil seal on the cavity and
maintaining the matching force.
B. Dust-proof lip: The role of preventing dust intrusion. The dust-proof lip is an
auxiliary lip that is not connected to the spring.
C. Lip end (sliding surface): The lip end is in the shape of a wedge and presses the shaft
surface at the end to seal the fluid.
D. Sealing lip: It is a flexible elastomer, designed to ensure that it can maintain
a stable sealing effect under the influence of mechanical vibration
and pressure fluctuations of the sealing fluid, and maintain a
stable contact state with the shaft surface at the end of the lip
effect.
