10-1 Selection of cushion
<Air cushion>
Standard Hyrodless Monosashi-kun is equipped with an air cushion.
Air cushion is installed not to operate piston at low speed when piston approaches to stroke end, but
to avoid shock when piston with large kinetic energy stops at stroke end. The range of load and speed
absorbed by air cushion is within the limit line of air cushion in graph.
<Stroke adjustment unit with shock absorber>
This is used on the occasion when operating with load and speed of over the limit line of air cushion or
when cushion is needed out of the air cushion stroke range due to stroke adjustment.
<L-Unit>
This is used on the occasion when cushion is needed out of the air cushion stroke range although
load and speed are within the limit line of air cushion or when operatin g with the range of load and
speed of over the air cushion limit line and below the unit limit line.
<Note>
①
Absorbing capacity of unit is for the occasion when all stroke of equipped shock absorber is used.
When effective stroke becomes shorter due to stroke adjustment, absorbing capacity becomes
extremely small. Therefore, fix adjustment bolt to project 0.5mm above shock absorber.
②
When shock absorber is used in the range of air cushion stroke, air cushion needle shall be
almost full opened (about one and a half turn from the position of full close.)
