Absorption Capacity of Rubber Bumper (MY3A)
Rubber Bumper Displacement (Additional Stroke due to Pressure on Each Side)
The stop position of the built-in rubber bumper of the MY3A series varies depending on the operating pressure. For alignement at
the stroke end, find the guideline for the stroke end position in operation as follows. Find the incremental displacement at the op-
erating pressure in the graph and add it to the stroke end position at no pressurization. If positioning accuracy is required for the
stop position at the stroke end, consider installing an external positioning mechanism or switching to the air cushion type (MY3B).
Note) In vertical operation, find the guideline for the stroke end position by adding, in case of the lower end, or subtracting, in case of the upper end, the pressure displacement equivalent to the self weight of the load.
