About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-40S
The AirTAC SAIJ160X900-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to dial back the nominal 900 mm travel by up to 40 mm. This yields an effective usable window of 860-900 mm, providing exact end-position tuning during commissioning without swapping the barrel or adding external stops. It delivers a substantial 10053 N pull force at 0.5 MPa, making it suitable for heavy machinery.
This variant includes a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and features a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the unit operates at speeds between 30-500 mm/s. The rear adjuster acts purely as a mechanical stop to set the travel end; it does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-40S Is Used
Heavy Machinery Changeover
Fine-tune the 860-900 mm retract stop during product size changeovers on large presses without disassembling the cylinder setup.
Variable End-Stop Positioning
Dial in the exact end position during machine commissioning using the rear screw, avoiding the need to swap out the entire barrel.
Heavy Material Handling
Utilize the 10053 N pull force to move heavy pallets or parts, relying on the adjuster to set the precise unloading point.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-40S the Right Cylinder?
Choose this 160 mm bore when your application requires high thrust, such as the 10053 N pull force at 0.5 MPa, stepping up from a 125 mm bore that provides 5734 N. The adjustable 860-900 mm window is ideal for product-size changeovers on a line, allowing operators to fine-tune the retract position quickly. For load-holding without continuous air pressure, this cylinder is not a lock; you should consider the AirTAC SAIL or BSAI series instead.
Because the 900 mm stroke is long, the 40 mm rod diameter and M36x2 thread provide robust rigidity, but an external guide is strongly recommended to prevent rod sagging and side-load damage. To match this ISO 15552 replacement exactly, specify the 160 mm bore, 900 mm stroke, 40 mm adjustment, PT tapered ports, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.
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 SAIJ160AX900-40S FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of pull force and 14074 N of push force. The maximum operating pressure is 1.0 MPa.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 900 mm stroke by up to 40 mm, creating an 860-900 mm usable travel window. It only sets the end position and does not lock the load without live air pressure.
