Hydraulic pressure that is generated in cylinder dur to the inertia of load shall be set at less than the maximum allowable pressure.
The cylinder bosy is not applied to the cutting oil-proof specifications.
This cylinder is not equipped with an air bleeder.
If the piston touches the cylinder end at the stroke end, decelerate the cylinder to a speed lower than the minimum operating speed.

Note1) Consult with us separately in case that stroke other than above standard stroke (marked with )is desired.

Avoid use of a cylinder in such a manner that eccentric load applies to the cylinder. When you use of mounting accessories of rotary type is intended in particular, be sure to consult to us in advance.

Note) The valve in ( ) is show that when 2 switches mounting one by one at different channel by two positions.
Note) Only one switch of type WR and WS is available for bores 20/25/32 mm.
2 switches can fit on bore 40/50/63 mm at 2 different positions by different channel. Normally one fitting channel could only for one switch.
Note) There will cause interference when you use 2 contact switches for 10 stroke. Please adjust.
* When you select 2 non-contact switches for bore larger than 40 mm and more than 10 mm stroke, please fit the switches on different channel.
