About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X100-20
The AirTAC SAIJ160X100-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a robust 14074N of push force at 0.7MPa and uses a PT G3/4 port. The built-in rear stopper allows you to dial back the 100mm nominal stroke by up to 20mm, creating a precise 80-100mm usable travel window for exact end-position tuning during commissioning.
This heavy-duty actuator utilizes a 40mm carbon steel rod and M36x2 thread to handle significant side loads. It includes variable air cushions at both ends to decelerate the payload smoothly. The extruded aluminum barrel features sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches, though this specific SKU is configured without a magnet.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X100-20 Is Used
Heavy Press Fit Tuning
Dial in the exact 80-100mm insertion depth for heavy press fits during machine setup, allowing on-the-fly adjustments without swapping physical cylinders.
Product Changeover Stops
Adapt the retract position quickly on a production line handling varying product sizes, using the rear screw to set new end-stops in seconds.
Heavy Material Bending
Provide up to 14074N of push force at 0.7MPa for bending or forming thick materials, while fine-tuning the travel limit to prevent overbending.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X100-20 the Right Cylinder?
Select this 160mm bore when an application demands high thrust, specifically 14074N push at 0.7MPa, but requires a short 100mm stroke. If you need less force, stepping down to a 100mm bore yields 5497N push at 0.7MPa. Choose this adjustable SAIJ variant over a fixed-stroke SAI when you need to fine-tune the retract end-stop on product changeovers without adding external stops. The rear adjuster acts solely as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider the SAIL or BSAI series.
To match this ISO 15552 replacement exactly, specify a 160mm bore, 100mm stroke, 20mm adjustment range, PT G3/4 porting, and standard carbon steel rod. The available mounting set is restricted to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 40mm rod is substantial, it handles side loads well, but long unsupported strokes still require an external guide.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ160 Adjustable Cylinder SAIJ160X100-20 FAQ
At a 0.7MPa operating pressure, this 160mm bore cylinder generates 14074N of push force and 9425N of pull force. It can reach a maximum of 2050 kgf at 1.0MPa.
The rear adjuster screw lets you shorten the 100mm nominal stroke by up to 20mm, providing a usable travel window of 80-100mm. This allows you to set the exact end-position at commissioning without using external stops.
