About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X20-20
The AirTAC SAIJ160X20-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. With a nominal 20 mm stroke and a 20 mm adjustment screw, you can fine-tune the usable travel window all the way down to a 0 mm zero-stroke position without external stops. It delivers massive thrust, pushing 10053 N and pulling 9425 N at 0.5 MPa, making it ideal for heavy-duty clamping or pressing tasks.
This extruded aluminum profile barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches. The carbon steel piston rod features an M36x2 thread and a robust 40 mm diameter, providing excellent rigidity against side loads. Fluid must be filtered to 40 um, and the cylinder operates at pressures between 0.15 and 1.0 MPa.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X20-20 Is Used
Precision Pressing
Dial in the exact zero-position contact force for assembly presses, ensuring delicate components are not crushed during end-of-stroke commissioning.
Machine Changeover
Quickly adapt the retract end-stop during product family changeovers on a packaging line, reducing setup time without swapping actuators.
Heavy Clamping
Secure heavy workpieces using the 10053 N push force, tweaking the 0-20 mm travel window to accommodate varying part thicknesses.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X20-20 the Right Cylinder?
Select this 160 mm bore actuator when an application requires high force within a very short travel distance, as the 20 mm adjustment allows you to dial the end position down to a complete zero stroke. If you need less force, stepping down to a 125 mm bore yields 6136 N push at 0.5 MPa. The rear adjuster acts purely as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an AirTAC SAIL or BSAI series cylinder.
To match this ISO 15552 interchangeable cylinder, specify a 160 mm bore, 20 mm stroke, PT tapered port thread, carbon steel rod, and no magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR styles found on other series.

- ✓ 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 SAIJ160X20-20 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 2050 kgf.
The rear adjuster screw lets you shorten the effective travel from the nominal 20 mm down to 0 mm. It functions as a mechanical stop to fine-tune the end position during setup, but it does not lock the load without continuous air pressure.
