Vertical Operation - SMC Networks CY3R Series Operation Manual

2-2) Moment at stroke end
If the rodless cylinder is used for the load
with large inertia, the following operating
failures may be caused at stroke end.
As shown on Fig. 8-1, such a large inertial
load tries to keep on linear motion on the
guide thought the cylinder body stops at
stroke end. This produces the moment
applied to the cylinder body.
Fig. 8-1 Moment produced at stroke end
If the cylinder is kept operating in such a
condition, the wearing of external slider is
worn so much as to cause operating failure.
To avoid occurrence of the failure, as shown
on Fig. 8-2, use both of shock absorber and
stopper at the mounting space for the load
to absorb kinetic energy of the load and
adopt the mounting bracket longer than
center of axis of cylinder to prevent the
moment applied to the cylinder body.

３．Vertical Operation
If the cylinder is operated in vertical direction,
consider the same points as section 2.
3-1) Allowable load
Vertical operation makes the load act to
holding force of magnet and allows the load
less than horizontal operation.
Table 3 shows the allowable load for each size.
