About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-30S
The AirTAC SAIJ160X180-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the nominal 180 mm travel by up to 30 mm, creating a precise 150-180 mm usable window for end-position tuning. Built with an extruded aluminum barrel and a robust 40 mm carbon steel rod with an M36x2 thread, it handles heavy loads by generating 14074 N of push force and 9425 N of pull force at 0.7 MPa. The integrated -S magnet enables position feedback via CMSE reed or DMSE electronic solid-state sensors seated in the dual-side sensor grooves.
Because the adjuster acts purely as a mechanical stop on the retract end, it sets the travel boundary without holding the load in place without live air pressure. This heavy-duty actuator operates at speeds of 30-500 mm/s and utilizes 50 mm of variable air cushioning at both ends to manage kinetic energy. It supports a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-30S Is Used
Heavy Press Fine-Tuning
Dial in the exact 150-180 mm retract distance on a forming press to accommodate varying material thicknesses without repositioning the entire actuator assembly.
Automated Changeover Stops
Adjust the end-stop on the fly during product line changeovers, using the 30 mm trim window to set new operational positions quickly.
Large Assembly Positioning
Move heavy structural components using the 14074 N push force, relying on the 40 mm carbon steel rod to withstand significant side loads.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-30S the Right Cylinder?
Select this 160 mm bore actuator when an application demands high thrust—such as 18095 N push at 0.9 MPa—combined with the flexibility to fine-tune the retract distance during commissioning or product changeover without swapping hardware. If your force requirements are lower, stepping down to a 125 mm bore yields 8590 N push at 0.7 MPa, whereas moving up to a 200 mm bore provides 21991 N. The PT tapered porting ensures a tight pneumatic seal, and the -S magnet allows seamless integration with DMSE solid-state sensors for precise end-of-stroke verification.
When specifying a replacement, match the 160 mm bore, 180 mm nominal stroke, 30 mm adjustment range, PT port thread, and the required -S magnet. For any stroke length of 300 mm or more, an external guide is recommended to manage side load, though this 180 mm unit's 40 mm rod handles substantial bending moments. Remember that neither the rear adjuster nor the air cushions function as a lock; for true fail-safe load holding without live air, consider the SAIL or BSAI series.
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 SAIJ160X180-30S FAQ
At 0.7 MPa, this double-acting cylinder provides 14074 N of push force and 9425 N of pull force. At 0.9 MPa, the push force increases to 18095 N. The operational speed range for this 160 mm bore actuator is 30-500 mm/s.
The rear adjusting screw acts as a mechanical stopper that shortens the effective stroke from the nominal 180 mm down to a minimum of 150 mm. This allows you to fine-tune the retract end-position during setup, but it does not lock or hold the load without continuous air pressure.
