Series RB
Specific Product Precautions 3
Be sure to read before handling.
Refer to front matters 42 and 43 for Safety Instructions.
Mounting
Caution
6. Adjust the stopping time through the use of the stopper nut, as
follows:
Control the stopping time of the impact object by turning the stopper nut
in or out (thus changing length “a”). After establishing the stopper nut
position, use a hexagon nut to secure the stopper nut in place.

Service Life and Replacement Period of Shock Absorber
Caution
1. Allowable operating cycle under the specifications set in this
catalog is shown below.
1.2 million cycles RB0604, RB08„„
2 million cycles RB10„„ to RB2725
1 million cycles RBA„„„„, RBL„„„„
Note) Specified service life (suitable replacement period) is the value at
room temperature (20 to 25°C). The period may vary depending on
the temperature and other conditions. In some cases the absorber
may need to be replaced before the allowable operating cycle above.
Maintenance
Caution
1. Check the mounting nut is not loosen.
The shock absorber could become damaged if it is used in a loose
state.
2. Pay attention to any abnormal impact sounds or vibrations.
If the impact sounds or vibrations have become abnormally high, the
shock absorber may have reached the end of its service life. If this is
the case, replace the shock absorber. If use is continued in this state, it
could lead to equipment damage.
3. Confirm that abnormality, oil leakage, etc. in the outward surface.
When a large amount of oil is leaking, replace the product, because it is
believed to be happening something wrong with it. If it keeps on using, it
may cause to break the equipment which is mounted by this product.
4. Inspect the cap for any cracks or wear.
If the shock absorber comes with a cap, the cap could wear first. To
prevent damage to the impact object, replace the cap often.
Storage
Caution
1. Piston rod position while stored
If a piston rod is stored as pushed in for a long period of time (over 30
days), absorption capacity may decrease.
Avoid storing like this for a long time.
