Airtac SAIJ160 Adjustable Cylinder SAIJ160BX550-100
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160BX550-100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 550mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX550-100
The AirTAC SAIJ160X550-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 550 mm travel by up to 100 mm. This creates a highly flexible 450-550 mm usable stroke window, letting you fine-tune the retract end position during commissioning without swapping out the physical actuator. Featuring a robust 40 mm SUS304 stainless steel rod and PT tapered port threads, it delivers 10053 N of pull force at 0.5 MPa and safely operates at speeds between 30-500 mm/s.
This heavy-duty actuator utilizes an extruded aluminum barrel with sensor grooves on both sides for direct mounting of position switches. Because it is a profile cylinder rather than a tie-rod design, it offers a clean exterior while maintaining strict ISO 15552 mounting interface dimensions. The rear adjustment screw functions purely as a mechanical stop to set the travel end and relies on the integrated air cushions for deceleration; it does not lock or hold the load without continuous live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX550-100 Is Used
Machine Changeover
Quickly adjust the retract end-stop from 450 to 550 mm during product size transitions without changing the cylinder or adding external spacers.
Heavy Pressing Operations
Delivers up to 18095 N of push force at 0.9 MPa for pressing and forming tasks requiring exact, field-tunable end-position accuracy.
Large Mold Handling
The 40 mm SUS304 stainless rod handles heavy mold manipulation safely, while the rear screw allows precise positioning of large tooling.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX550-100 the Right Cylinder?
Selecting this 160 mm bore actuator makes sense when your application requires substantial push force, generating 14074 N at 0.7 MPa, but demands on-the-fly end-position tuning for varying product sizes. If your setup only needs fixed travel, the standard SAI cylinder is simpler, but the SAIJ rear adjuster removes the need for external mechanical stops during machine changeovers. If your process demands load-holding without continuous air pressure, a standard SAIJ will not suffice; you should instead look at the BSAI clamp-lock or SAIL air-released lock variants.
When specifying a replacement, verify the 160 mm bore, 550 mm nominal stroke, 100 mm adjustment range, PT port threads, and the SUS304 (code B) rod material. Because the 550 mm stroke is quite long, the 40 mm rod provides excellent rigidity, yet an external guide is strongly recommended to prevent side-load damage on the unsupported piston. This model uses the standard SAIJ mounting subset, including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets.
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 SAIJ160BX550-100 FAQ
At 0.5 MPa it provides 10053 N push and 9425 N pull force. At 0.9 MPa, the push force increases to 18095 N, with a maximum rated force of 2050 kgf at 1.0 MPa.
The rear adjuster screw lets you trim the effective stroke back from the 550 mm nominal position by up to 100 mm, creating a 450-550 mm travel window. The screw acts as a mechanical stop to set the end position and does not hold the load without live air pressure.
