About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-20
The AirTAC SAIJ160X135-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the effective travel. With a 135 mm nominal stroke and a 20 mm adjustment screw, it provides a 115-135 mm usable travel window for fine-tuning the retract end position at commissioning. This 160 mm bore generates 10053 N of pull force at 0.5 MPa, making it suited for heavy-duty positioning tasks.
The carbon steel rod is 40 mm thick with an M36x2 thread, providing a robust interface that handles high side loads, though long strokes still require external guiding. It uses a PT G3/4 port and includes variable air cushions at both ends with a 50 mm cushion length to manage kinetic energy. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. The extruded aluminum barrel omits tie-rod construction and includes sensor grooves on both sides for future CMSE or DMSE switches if a magnet is added.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-20 Is Used
Heavy-Duty Press Tuning
Dial in the exact 115-135 mm retract position during machine setup to ensure precise pressing force on large assemblies without external stoppers.
Product Size Changeover
Quickly adjust the end-of-stroke position on a packaging line when transitioning between different product sizes, using the 20 mm trim to adapt the travel window.
Assembly Line Calibration
Fine-tune the retract distance during commissioning of automated heavy machinery, leveraging the 10053 N pull force to move substantial jigs into their exact operational footprint.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-20 the Right Cylinder?
Select this adjustable model when a process requires exact end-position tuning without adding external stops or swapping the cylinder. The 20 mm adjustment window is ideal for product changeovers. If less force is needed, a 125 mm bore provides 5734 N of pull at 0.5 MPa. For higher thrust, a 200 mm bore offers 15080 N. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For load-holding without pressure, consider an external rod lock or the AirTAC SAIL or BSAI series. To match this ISO 15552 cylinder, specify a 160 mm bore, 135 mm stroke, 20 mm adjustment, PT G3/4 port, and the desired mounting.
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 SAIJ160X135-20 FAQ
At a 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of pull force and 14074 N of push force. At its maximum 1.0 MPa pressure, it delivers up to 2050 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 135 mm nominal stroke by up to 20 mm. This creates a 115-135 mm usable travel window for fine-tuning the end position during commissioning without replacing the cylinder.
