About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X120-10S
The AirTAC SAIJ160X120-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 110-120 mm usable travel window, allowing you to dial back the 120 mm nominal stroke by up to 10 mm during machine commissioning. Built with a carbon steel rod and a PT tapered port, it delivers 14074 N of push force at 0.7 MPa.
This extruded aluminum profile barrel includes dual sensor grooves compatible with DMSE solid-state electronic sensors and CMSE reed switches via the -S magnet option. The mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X120-10S Is Used
Heavy Press Tuning
Dial in the exact 110-120 mm end-of-stroke position during heavy press commissioning to accommodate material thickness variations without external shims.
Product Changeover
Quickly adjust the retract stop for different product sizes on a high-thrust line, shifting the end position by up to 10 mm in seconds.
Large Fixture Clamping
Secure large machined components using 14074 N of force at 0.7 MPa, fine-tuning the clamping depth to prevent workpiece distortion.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X120-10S the Right Cylinder?
Choose this 160 mm bore when an 80 mm bore (3518 N push at 0.5 MPa) lacks the thrust for heavy positioning tasks but a 200 mm bore is physically too large. The 10 mm adjustable end-stop is ideal for fine-tuning the retract position on product changeovers without adding external stops or swapping to a fixed-stroke SAI cylinder. For load-holding without continuous air pressure, use an external pilot-operated check valve or select the SAIL or BSAI series instead of relying on the adjuster. To match this ISO 15552 footprint, specify the 160 mm bore, 120 mm stroke, 10 mm adjustment, PT port, and -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 SAIJ160X120-10S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder generates 14074 N of push force and 9425 N of pull force. It can deliver up to 18095 N push at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that shortens the effective travel from the 120 mm nominal stroke down to a minimum of 110 mm. It sets the end position but does not lock the load without live air pressure.
