About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-75
The AirTAC SAIJ160X260-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 75 mm. This creates a highly flexible 185-260 mm usable stroke window, letting you dial in the exact retract end-position during commissioning without adding external stops. Built with an extruded aluminum barrel, it delivers massive force, pushing with 14074 N at 0.7 MPa.
This heavy-duty unit uses a 40 mm SUS304 stainless steel rod with an M36x2 thread, offering excellent corrosion resistance and robust side-load capacity. Fluid is filtered air operated at 0.15-1.0 MPa, and the PT tapered porting ensures a tight, reliable seal. It reaches speeds of 30-500 mm/s and includes adjustable air cushions at both ends to manage the high kinetic energy of the 160 mm bore.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-75 Is Used
Heavy Machinery Changeover
Dial in the 185-260 mm travel window during equipment setup to accommodate different large product sizes without physically replacing the actuator.
End-Position Tuning
Fine-tune the retract stopper during commissioning to achieve exact positioning without fabricating custom external mechanical stops.
High-Force Positioning
Leverage the 14074 N push force at 0.7 MPa to move and halt heavy assemblies precisely within the adjustable travel limits.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-75 the Right Cylinder?
Choose this 160 mm bore when a 125 mm bore (providing 8590 N push at 0.7 MPa) cannot meet your thrust requirements, but you want to avoid stepping up to a massive 200 mm body. The 75 mm adjustment range is ideal for product changeovers on large machinery, allowing rapid end-stop modifications without physically swapping the cylinder. It utilizes the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. Because the stroke is 260 mm, ensure an external guide supports the load to prevent excessive side-loading on the 40 mm rod. Remember that the rear adjuster is a travel stop, not a lock; for load-holding without live air pressure, specify a SAIL or BSAI cylinder.
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 SAIJ160BX260-75 FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides a push force of 14074 N and a pull force of 9425 N.
The rear adjuster acts as a mechanical stop that lets you shorten the 260 mm nominal stroke by up to 75 mm, creating a 185-260 mm usable travel window for fine-tuning at commissioning.
