7. Ensure that the hardness of the surface directly impacting
the piston rod of the shock absorber is over HRc40
(excluding models with cap).
8. Be aware that performance and characteristics change
depending on the operating temperature.
4. For swing impacts, ensure that the angle of eccentricity
between the load direction and the center line of the shock
absorber is at or below the specification values shown as
following. For KSHJ14×12(C) (outer diameter M14) or
smaller models, 1°or bellow. For KSHJ16×15(C) (outer
diameter M16) or larger models, 3°or bellow.
(For KSHJ42×70(C) models, 1°or bellow. )
5. The small screw on the back end of the shock absorber
should never be loosened or removed. Oil may leak out of
the shock absorber leading to a loss of functionality and
resulting in damage to the equipment and accidents.
1. Mount the shock absorber so that the load contacts at the
center of the rod, and it is not subjected to off-centered loads.
An off-centered load could result in breakage or defective rod
returns.
2. To adjust the capacity with the stroke, adjust the stopper nut
(-S) or add an external stopper.
3.
If using with a cap, always mount a stopper nut (-S) or an
external stopper to ensure that the cap is not subjected to
loads at the stroke end. The stopper nut mounting position
must not exceed the distance shown in the table below.
You can use it without a stopper nut or external stopper, but
over the long-term, the stop location changes due to cap
deformation and wear.
6. When mounting the shock absorber, always use the following
maximum tightening torque guidelines. Tightening using
excessive force may result in damage.
Mounting
Cover the unit when mounting it in locations where it might be subject
to excessive dust, dripping water, dripping oil, etc. Dents, scratches,
water, oil, or dust on the piston rod results in damage and decreases
service life.
