About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-40S
The AirTAC SAIJ160X225-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a massive 18095N push force at 0.9 MPa. It features a durable SUS304 stainless steel rod and a built-in magnet for position sensing. By turning the rear stopper screw, you achieve a usable travel window of 185 to 225 mm, allowing precise end-position tuning without swapping hardware.
This bore size utilizes a G3/4 port and a robust M36x2 rod thread to handle high side loads, while adjustable air cushions at both ends manage deceleration. The extruded aluminum barrel includes sensor grooves on both sides, directly supporting AirTAC CMSE reed and DMSE electronic solid-state switches for tight feedback loops.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-40S Is Used
Heavy Machinery Changeover
Quickly adapt large pressing or clamping stations to new part dimensions by adjusting the stroke within the 185-225 mm window without changing the cylinder.
Precision End-Stop Tuning
Fine-tune the final retract position during commissioning to achieve exact mechanical alignment, preventing costly collisions in high-force applications.
Variable Product Handling
Accommodate varying package or pallet sizes on a heavy-duty transfer line by simply turning the rear adjuster screw to shorten the effective travel.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-40S the Right Cylinder?
Choose this 160 mm bore when an 80 mm bore (yielding 4523N push at 0.9 MPa) cannot meet your thrust requirements. The 40 mm adjustment range is ideal for product changeovers on heavy machinery, letting you dial in the exact 185-225 mm stroke mechanically. Because the stroke is 225 mm, ensure external guiding is used to protect the rod from excessive side loads. Mounting options are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).
For a direct ISO 15552 replacement match, specify a 160 mm bore, 225 mm nominal stroke, 40 mm adjustment, PT tapered ports, and the -S magnet option. Remember that the rear adjuster acts only as a travel stop, not a lock; the cylinder will not hold a load without live air. If you need true load-holding, consider the SAIL or BSAI series instead.
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 SAIJ160BX225-40S FAQ
At an operating pressure of 0.9 MPa, this 160 mm bore cylinder generates a push force of 18095N and a pull force of 9425N. It operates efficiently at speeds between 30 and 500 mm/s.
The rear adjuster screw allows you to mechanically shorten the nominal 225 mm stroke by up to 40 mm, providing an effective travel window of 185 to 225 mm. This stopper sets the end position but does not lock the load without continuous air pressure.
