Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-30S
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 225mm 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 SAIJ160BX225-30S
The AirTAC SAIJ160X225-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 225 mm travel by up to 30 mm. This creates a precise 195-225 mm usable window for fine-tuning end positions during commissioning without swapping hardware. Belonging to the 160 mm bore class, it delivers substantial thrust, generating 14074 N of push force and 9425 N of pull force at 0.7 MPa. The extruded aluminum barrel features sensor grooves on both sides, and this specific SKU includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic solid-state switches.
This variant uses a SUS304 stainless steel rod (code B) for superior corrosion resistance and carries a robust M36x2 rod thread. It operates at speeds of 30-500 mm/s and utilizes PT tapered ports sized at G3/4. The adjustable stopper acts solely as a travel end-setter and deceleration aid alongside the standard air cushions; it is not a locking mechanism and cannot hold a load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-30S Is Used
Heavy Press Tuning
Dial in the exact 195-225 mm end-stop during heavy press commissioning to accommodate material thickness variations without machining new spacers.
Product Changeover
Rapidly adjust the retract position on a packaging line when switching to a different pallet size, using the rear screw rather than swapping the entire actuator.
Assembly Station Setup
Fine-tune the stroke on automated assembly lines to ensure precise contact forces, preventing damage to components during high-force insertion tasks.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-30S the Right Cylinder?
Choose this 160 mm bore adjustable-stroke cylinder when an application requires heavy force within a specific 195-225 mm travel band, avoiding the need for external stops during machine setup or product changeover. If your thrust requirements are lower, stepping down to a 125 mm bore yields 8590 N of push force at 0.5 MPa, while stepping up to a massive 200 mm bore provides 21991 N at 0.7 MPa. For holding loads without continuous air pressure, this cylinder is insufficient; you should instead select a SAIL (air-released lock) or BSAI (clamp-lock) variant, or integrate an external rod lock.
To replace an existing ISO 15552 cylinder, match the 160 mm bore, 225 mm stroke, 30 mm adjustment range, G3/4 PT ports, and the -S magnet requirement. SAIJ supports a reduced mounting interface subset consisting of Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. Because the 225 mm stroke is under the 300 mm side-load threshold, standard mounting is generally sufficient, though the heavy M36x2 rod thread handles incidental side loads well.
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 SAIJ160BX225-30S FAQ
The rear adjuster screw allows you to shorten the effective travel from the 225 mm nominal stroke by up to 30 mm, providing a usable window of 195-225 mm. This stopper sets the end position and aids deceleration alongside the air cushion, but it does not lock or hold the load without live air pressure.
At 0.7 MPa operating pressure, the SAIJ160X225-30-S generates a push force of 14074 N and a pull force of 9425 N. It can deliver a maximum push force of 18095 N at 0.9 MPa.
