About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX850-30
The AirTAC SAIJ160X850-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 850 mm travel to a precise 820-850 mm window. It delivers heavy thrust, pushing 18095 N at 0.9 MPa, making it suitable for demanding industrial pressing and lifting tasks. The extruded aluminum barrel features sensor grooves on both sides for straightforward position feedback.
This variant features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. The rear stopper acts purely as a travel end stop for commissioning fine-tuning and does not lock the load without live air pressure. For position holding without pneumatic pressure, an external SAIL locking cylinder or pilot-operated check valve is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX850-30 Is Used
Press Fit Tuning
Dial in the exact 820 to 850 mm insertion depth for heavy press-fit assemblies without swapping out the entire pneumatic cylinder.
Product Changeover
Adjust the rear stopper quickly during packaging line size changes to accommodate different large-format pallet heights.
Heavy Lifting Setup
Leverage the 18095 N push force at 0.9 MPa for heavy lifting tasks while fine-tuning the end-of-stroke deceleration during machine commissioning.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX850-30 the Right Cylinder?
Choose this 160 mm bore when a 125 mm bore (delivering 11045 N push at 0.9 MPa) cannot meet your force requirements, but a 200 mm bore (28274 N) would be excessive. The 30 mm adjustment window is ideal for product changeovers on a line, letting you fine-tune the end position without adding external mechanical stops or swapping the cylinder. Because the total stroke is 850 mm, the 40 mm diameter rod and M36x2 rod thread provide substantial rigidity, but an external guide rail is strongly recommended to prevent excessive side-loading on the long unsupported piston rod.
To match this exact ISO 15552 footprint for replacement, specify the 160 mm bore, 850 mm stroke, 30 mm adjustment range, PT tapered port threads, and the SUS420J2 rod material. Note that this model does not include a magnet (-S), so it requires external limit switches or a later sensor-equipped variant for automated feedback. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
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 SAIJ160AX850-30 FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder provides a push force of 18095 N and a pull force of 9425 N. At 0.5 MPa, the push force is 10053 N.
The rear adjuster screw allows you to shorten the effective travel from the nominal 850 mm down to 820 mm. This creates a 30 mm adjustable window for fine-tuning the end position at commissioning, but the screw acts only as a stop and does not lock the load without continuous air pressure.
