About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-30S
The AirTAC SAIJ160X800-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers 14074N of push force at 0.7 MPa and provides a usable travel window of 770-800mm. The -S variant includes a magnet for position sensing and uses a SUS420J2 stainless steel rod (code A) for improved corrosion resistance.
This model uses PT tapered ports and reaches speeds of 30-500mm/s. The rear stopper screw lets you dial in the exact end position during commissioning without adding external stops. It is a travel stop, not a lock, so it will not hold a load without live air. For load-holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-30S Is Used
Machine Setup Tuning
Dial in the exact 770-800mm retract end-position during initial commissioning without swapping cylinders or adding external mechanical stops.
Product Changeover
Adjust the travel window on the fly to accommodate different product sizes on a packaging line, ensuring precise positioning.
Heavy Assembly Press
Leverage the 14074N push force at 0.7 MPa for heavy-duty assembly operations while retaining the flexibility to fine-tune the stroke.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-30S the Right Cylinder?
Choose this 160mm bore when you need substantial thrust, such as 14074N at 0.7 MPa, but require fine-tuning at the retract end. If your application needs less force, stepping down to a 100mm bore yields 5497N. Conversely, a 200mm bore provides 21991N. The SAIJ is chosen over a fixed SAI cylinder when product changeovers require variable end-stops.
Because this cylinder has an 800mm stroke, the 40mm rod and M36x2 thread carry significant side load, but an external guide is still recommended for the long unsupported travel. It is dimensionally interchangeable with ISO 15552 cylinders. To match this configuration, specify bore, stroke, 30mm adjustment, PT ports, SUS420J2 rod, and the -S magnet.
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 SAIJ160AX800-30S FAQ
At 0.7 MPa operating pressure, this 160mm bore cylinder provides 14074N of push force and 9425N of pull force. The maximum push force reaches 18095N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that lets you trim the effective stroke back by up to 30mm. For an 800mm nominal stroke, this creates a usable travel window of 770-800mm for precise end-position tuning.
