About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-10S
The AirTAC SAIJ160X140-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 140 mm nominal stroke that can be fine-tuned down by 10 mm, yielding a usable travel window of 130-140 mm. Delivering a substantial 10053 N pull force at 0.5 MPa, it is built for heavy-duty positioning tasks.
This unit includes a standard carbon steel rod and a magnet for position sensing. The extruded aluminum barrel features sensor grooves on both sides to accept CMSE reed and DMSE electronic solid-state switches. It supports a speed range of 30-500 mm/s and uses PT tapered port threading (G3/4) for high flow requirements.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-10S Is Used
Heavy Press Tuning
Dial in the exact 130-140 mm travel window during machine commissioning to set precise contact depth on heavy press operations without external stopper blocks.
Product Size Changeover
Quickly adapt the end-stop position on packaging lines when switching between product sizes, using the rear adjuster to trim the stroke by up to 10 mm.
Robotic Fixture Alignment
Fine-tune the retract position of heavy pneumatic clamps on automated assembly lines to ensure perfect alignment with mating parts.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-10S the Right Cylinder?
Select this 160 mm bore when 100 mm or 125 mm bores lack sufficient thrust, stepping up from the 125 mm bore which provides 5734 N pull at 0.5 MPa. The 10 mm rear adjuster is ideal for dialing in exact end-of-stroke positions during commissioning without adding external stops. For load-holding without live air pressure, select a SAIL pneumatic lock or BSAI clamp-lock cylinder instead, as this adjuster acts only as a travel stop.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 140 mm stroke, 10 mm adjustment, PT G3/4 port, and -S magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 140 mm stroke is under 300 mm, side-load concerns are minimal, but the robust 40 mm rod and M36x2 thread handle high axial and offset stresses effectively.
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 SAIJ160X140-10S FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of pull force and 14074 N at 0.7 MPa. The maximum thrust is 2050 kgf at 1.0 MPa.
The rear adjuster screw acts as an external stopper that lets you shorten the 140 mm stroke by up to 10 mm, creating a 130-140 mm usable travel window. It only sets the end position and deceleration; it does not lock the load without live air pressure.
