About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-50
The AirTAC SAIJ160X260-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 210 to 260 mm, letting you dial back the nominal 260 mm stroke by up to 50 mm during machine commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible positioning of CMSE reed or DMSE electronic switches.
Delivering 10053 N of push force and 9425 N of pull force at 0.5 MPa, this bore size handles heavy loads. The SUS304 stainless steel rod (material code B) offers superior corrosion resistance for harsher environments, while the PT tapered port threads ensure a robust, sealed pneumatic connection. The rear adjuster acts purely as a mechanical stop to set the end position and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-50 Is Used
Heavy Press Tuning
Fine-tune the 210-260 mm travel window during setup to apply exact clamping force on large assemblies without swapping cylinders.
Product Changeover
Quickly adjust the rear stopper to accommodate varying product lengths on a high-force production line.
Corrosive Assembly
Leverage the SUS304 stainless steel rod and 10053 N thrust for robust actuation in washdown or chemically exposed environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-50 the Right Cylinder?
Choose this 160 mm bore when a 125 mm cylinder (providing 6136 N push at 0.5 MPa) cannot move your load, but you want to avoid stepping up to a 200 mm bore. The adjustable 210-260 mm travel is ideal for product changeovers where exact end-positioning varies per run, unlike a fixed-stroke SAI cylinder. To match this ISO 15552 replacement exactly, verify the 260 mm stroke, 50 mm adjustment, PT porting, and SUS304 rod. Since the stroke is 260 mm, ensure your mounting setup prevents excessive side loading on the long unsupported rod. For load-holding without live pressure, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster is not a lock.
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 SAIJ160BX260-50 FAQ
The rear adjuster lets you mechanically shorten the effective travel from 260 mm down to 210 mm. This creates a 50 mm tuning window for precise end-position setup at commissioning without needing external stops.
At 0.5 MPa operating pressure, it provides 10053 N of push force and 9425 N of pull force. It can reach up to 2050 kgf at its maximum 1.0 MPa pressure rating.
