About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-30
The AirTAC SAIJ160X225-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 195 to 225 mm during commissioning. Delivering a robust 14074 N of push force at 0.7 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread for a high-integrity pneumatic seal.
The extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting. Because this is a 160 mm bore variant operating at 30-500 mm/s, the 40 mm rod diameter and M36x2 thread provide high structural rigidity, though long unsupported strokes still necessitate an external guide to prevent excessive side-loading.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-30 Is Used
Heavy Press Tuning
Dial in the exact 195-225 mm end-stop during machine setup to accommodate varying material thicknesses on a heavy-duty press line.
Product Changeover
Quickly adjust the retract end-position for new pallet sizes on a conveyor without physically replacing the cylinder or adding external stopper blocks.
Fixture Alignment
Fine-tune the clamping travel on large machining fixtures to ensure precise positioning of oversized metal components.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-30 the Right Cylinder?
Select this 160 mm bore cylinder when an application requires heavy thrust up to 14074 N at 0.7 MPa, but demands on-the-fly end-position tuning without swapping out the physical barrel. If your process requires less force, stepping down to a 125 mm bore yields 8590 N at the same pressure, whereas stepping up to a 200 mm bore provides 21991 N.
The rear adjuster screw acts purely as a mechanical stop to trim the stroke; it does not lock the load or hold position without live air pressure. For secure load-holding, consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external pilot-operated check valve. When replacing an ISO 15552 cylinder, match the 160 mm bore, 225 mm nominal stroke, 30 mm adjustment range, PT port threads, and your required mounting interface from the available SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2.
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 SAIJ160BX225-30 FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. The maximum thrust is 2050 kgf at 1.0 MPa.
The external rear adjuster screw lets you shorten the effective travel from the nominal 225 mm down to 195 mm. This allows precise end-position tuning at commissioning, but it functions only as a travel stop and does not lock the load without continuous air pressure.
