Airtac SAIJ160 Adjustable Cylinder SAIJ160BX45-40S
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160BX45-40S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 45mm 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 SAIJ160BX45-40S
The AirTAC SAIJ160X45-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 14074N of push force at 0.7 MPa. It features a SUS304 stainless steel rod (code B) and a PT tapered port thread. The integrated -S magnet enables precise position detection using AirTAC CMSE reed or DMSE electronic solid-state sensors housed in the dual-side extruded aluminum barrel grooves.
With a 45 mm nominal stroke and a 40 mm adjustment code, this model provides a usable travel window of 5 to 45 mm. This wide adjustment range on a short-stroke heavy-duty actuator allows operators to dial in exact retract end-positions during commissioning without adding external stops. The rear screw acts purely as a travel stop and does not lock the load; for position holding without live air pressure, an external rod lock or the AirTAC SAIL series is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX45-40S Is Used
Short-Stroke Pressing
Delivers 14074N of thrust at 0.7 MPa for high-force pressing, with the 40 mm adjuster allowing exact bottoming position tuning without changing tooling.
Machine Changeover
Quickly modify the retract end-stop within the 5 to 45 mm window to accommodate different product heights on the same production line.
Heavy-Duty Clamping
Uses the SUS304 stainless steel rod to securely clamp large workpieces in harsh environments, relying on live air to maintain the holding force.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX45-40S the Right Cylinder?
Selecting this 160 mm bore cylinder makes sense when an application demands high thrust, such as the 10053N push force at 0.5 MPa, within a very confined stroke envelope. If the job requires less force, stepping down to a 125 mm bore yields 6136N at 0.5 MPa, whereas moving up to a 200 mm bore provides 15708N. The adjustable 5-45 mm window is ideal for short-press or clamping duties where the exact end-position changes per job. Unlike a fixed SAI cylinder, this adjustable variant prevents the need to swap hardware during product changeovers.
To replace an ISO 15552 cylinder, match the 160 mm bore, 45 mm nominal stroke, 40 mm adjustment, G3/4 port, and -S magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the stroke is under 300 mm, external side-load guides are less critical, though the robust 40 mm rod and M36x2 thread handle substantial offset loads effectively.

- ✓ 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 SAIJ160BX45-40S FAQ
At 0.5 MPa it provides 10053N of push force and 9425N of pull force. At 0.7 MPa, the push force increases to 14074N, with a maximum rated push force of 18095N at 0.9 MPa.
The 45 mm nominal stroke combined with the 40 mm adjustment code allows the effective stroke to be fine-tuned anywhere within a 5 to 45 mm window. The rear screw sets the travel end but does not lock the load without continuous air pressure.
