About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-20S
The AirTAC SAIJ160X260-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 240 to 260 mm, letting you dial back the nominal 260 mm stroke by up to 20 mm during machine setup. Built for heavy tasks, it yields 10053 N of pull force at 0.5 MPa and 14074 N of push force at 0.7 MPa.
This unit uses a SUS304 stainless steel rod for superior corrosion resistance and carries the -S magnet option for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides. It operates at 30-500 mm/s and uses PT tapered G3/4 ports.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-20S Is Used
Heavy Press Tuning
Fine-tune the 240-260 mm travel window on heavy assembly presses to accommodate varying material thicknesses without mechanical rebuilds.
Product Changeover
Rapidly adjust end-stops during automated line changeovers to handle different product sizes, using the rear screw to set exact retraction depths.
Fixture Positioning
Dial in exact clamping positions on large fixtures, leveraging the 10053 N pull force and SUS304 rod for robust, corrosion-free operation.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-20S the Right Cylinder?
Choose this 160 mm bore when 125 mm falls short at 6136 N push force, or step down if 200 mm is excessive at 15708 N. The adjustable rear stopper allows precise end-position tuning at commissioning without swapping cylinders or adding external stops. Remember that the adjuster is a travel stop, not a lock; it will not hold a load without live air. For secure load-holding without pressure, use an external rod lock or consider the SAIL or BSAI series.
To match this ISO 15552 cylinder, verify the 160 mm bore, 260 mm stroke, 20 mm adjustment range, G3/4 PT ports, SUS304 rod, and the -S magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Since the stroke exceeds 300 mm is not the case here, standard mounting suffices, but long unsupported strokes still need an external guide to manage side load.
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 SAIJ160BX260-20S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from 260 mm down to 240 mm. It trims the travel end for precise commissioning but does not lock the load without live air pressure.
At 0.5 MPa, it provides 10053 N of pull force and 9425 N of push force. At 0.7 MPa, the push force increases to 14074 N, making it suitable for heavy-duty applications.
