About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX55-40S
The AirTAC SAIJ160X55-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end position without swapping components. It provides a usable travel window of 15-55 mm, letting you dial back the nominal 55 mm stroke by up to 40 mm during commissioning. Delivering a pull force of 9425 N at 0.5 MPa, it handles heavy loads with precision.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and operates at speeds of 30-500 mm/s. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet supports AirTAC CMSE reed and DMSE electronic sensors for exact position feedback. PT tapered ports ensure a tight pneumatic seal.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX55-40S Is Used
Machine Changeover
Quickly adjust the 15-55 mm travel window during product size changes without replacing the cylinder or adding external mechanical stops.
Heavy Clamping
Utilize the 9425 N pull force at 0.5 MPa to secure heavy workpieces, using the rear adjuster to set the exact clamping depth.
End-Position Tuning
Fine-tune the retract end position during commissioning to perfect machine timing, leveraging the 40 mm adjustment range.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX55-40S the Right Cylinder?
Choose this 160 mm bore when you need substantial thrust, such as the 9425 N pull force at 0.5 MPa, but require a short, highly adjustable travel window. If your application needs less force, stepping down to a 125 mm bore yields 5734 N of pull force. The adjustable rear stopper is ideal for product changeovers, acting as a travel limit rather than a lock, meaning it cannot hold the load without live air pressure. For load-holding requirements, consider an external rod lock or the SAIL series.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 55 mm stroke, 40 mm adjustment, PT ports, and the -S magnet option. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 40 mm diameter rod is robust, it handles high side loads well, though external guides are still recommended for optimal longevity.
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 SAIJ160BX55-40S FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 2050 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 40 mm. This creates a usable travel window of 15-55 mm, allowing precise end-position tuning without changing the cylinder.
