Outline dimensional drawing
(Unit: mm)
ø20 (20‑mm diameter) dimensional outline drawing
Note 1) The figure shows dimensions at the maximum energy absorption capacity.
Note 2) The dimensional outline drawing for the model with auto switch is identical to the above.
Note 3) The figure shows an extended piston rod.
Note 4) The dimensions marked with * vary according to adjustment of the shock absorber dial.
Note 5) Circumscribed circle ø47 (47‑mm diameter) means the diameter of the circle circumscribed to the cylinder tube angles. The mounting hole diameter must be ø48 (48‑mm diameter). Be careful of the interference between the lever and the mounting base when mounted from the lever side. Thus, the thickness of the mounting base must be 8 mm or less.
Note 6) It is recommended to set the conveyor height in a range from the lower limit position to the upper limit position of the conveyor (dimension *3 shown in the figure).
Note 7) The dimensions in the figure do not include the stroke length tolerance (0 to +1.4 mm). When fixing the cylinder (setting the conveyor position), take this into consideration and be sure to set the cylinder within the range of Note 6, using the upper limit position of the conveyor (roller center position) as a reference.

Note 4) The dimensions marked with * vary according to adjustment of the shock absorber dial.
Note 5) Circumscribed circle ø62 (62‑mm diameter) means the diameter of the circle circumscribed to the cylinder tube angles. The mounting hole diameter must be ø63 (63‑mm diameter). Be careful of the interference between the lever and the mounting base when mounted from the lever side. Thus, the thickness of the mounting base must be 9 mm or less.

Operation Precautions
- 1. In case of cylinders with locking mechanism, do not apply an external force from the opposite side when the lever is locked. Lower the cylinder before adjusting the conveyor or moving the pallet.
- 2. In case of cylinders with locking mechanism, do not collide the pallet and roller when the lever is locked. If the pallet collides with the roller in the locked state, it may cause lever malfunction. (The lever is released when the cylinder is fully retracted.)
- 3. Do not let your hand become caught when operating the cylinder. The lever holder goes up and down while the cylinder is in operation. Pay sufficient attention not to let your hand or fingers become caught between the rod cover and lever holder.
- 4. Do not let water, cutting oil or dust splash on the equipment. It can cause oil leakage and malfunction of the shock absorber.
- 5. The stop state of the workpiece may vary depending on changes in ambient temperature or secular changes in shock absorber resistive force. Check the stop state periodically and adjust the shock absorber resistive force at appropriate intervals.
