Cylinder barrel
Mounting
1. While any mounting direction in the slit type rodless cylinders
ORV
series is allowed, mount the piston yoke so that it faces
downward or protect it with a cover, etc., when mounting in
locations subject to dripping water or oil, etc., or to large
amounts of dust.
2. Avoid any electric welding either during or after mounting the
slit type rodless cylinders
ORV
series. Flows of welding cur-
rent to the cylinder could generate arcs that result in damage
or depositions of the seal band.
3. Be careful to avoid making scratches or dents, etc., on the
cylinder barrel.
4. If using in locations where the cylinder can easily become
smeared, clean the cylinder periodically. After cleaning,
always apply grease to the sliding portion of the cylinder bar-
rel and outer seal band surface.
5. Mount the cylinder barrel so that it cannot be twisted.
Insufficient flatness of the mounting surface could result in
cylinder barrel twisting, damaged bands, air leaks, and
operating malfunctions.
6. Precautions for the supporting types
7. When the total cylinder length is long, the load could give a
large deflection that could result in defective operation. If the
relationship between the load on a 2-point support at both
ends and the stroke exceeds the range shown in the graphs
below, always use an F-type support at an intermediate
position.

For 2-point support at both ends, and 3-point support, always mount so
that the cylinder barrel is supported underneath both ends by at least
10mm [0.394in.] of contact area.
Support on bottom surface of barrel

When supported directly on the bottom surface of the barrel, as shown
above, the load can be applied without mounting other supports.
