Handling Instructions and Precautions
The “mass” in the graph refers to the total mass carried by the
ORV
series. “Impact speed” refers to the speed immediately
before striking the rubber bumper or shock absorber. Note that
this is not the same as “average speed (cylinder stroke/time
required).”
(See “Impact speed graph” to the lower right.)

Shock absorber absorption capacity
The slit type rodless cylinders
ORV
series uses shock
absorbers as optional equipment. The absorbable mass and
impact speed, however, lie within the “with shock absorber”
range shown in the “rubber bumper and shock absorber
capacity graph” to the right. Do not use it when the maximum
impact speed exceeds 800mm/s [31.5in./sec.].
The slit type rodless cylinders
ORV
series comes with rubber
bumpers as standard equipment. The absorbable mass and
impact speed, however, lie within the “no shock absorber”
range shown in the “rubber bumper and shock absorber
capacity graph” below. Do not use it when the maximum impact
speed exceeds 500mm/s [19.7in./sec.].
1kg = 2.205lb.
1mm/s = 0.0394in./sec.
1kg = 2.205lb.
1mm/s = 0.0394in./sec.
The graph below shows the impact time at 800mm/s
[31.5in./sec.] and 500mm/s [19.7in./sec.] for each stroke of the
table at the end of the stroke.
For use, set the times on the upper side of the curve.
