About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-75
The AirTAC SAIJ160X225-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 225 mm stroke with a usable travel window of 150 to 225 mm, allowing you to dial back the retract position by up to 75 mm during commissioning. Equipped with a SUS304 stainless steel rod and PT tapered ports, it delivers 10053 N of push force at 0.5 MPa.
This adjustable stopper lets you fine-tune end positions on product changeovers without swapping the cylinder or adding external stops. The rear adjuster and variable air cushions only decelerate the travel end; they do not hold the load without live air. For position holding, use a SAIL lock or BSAI clamp-lock cylinder.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-75 Is Used
Heavy Press Tuning
Dial in the exact 150 to 225 mm end position during heavy press commissioning without external stopper hardware.
Product Changeover
Quickly adjust the retract stop for varying product sizes on a machining line, saving setup time.
Material Forming
Leverage 10053 N of thrust at 0.5 MPa for forming applications requiring precise, repeatable stroke limits.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-75 the Right Cylinder?
Choose this 160 mm bore when you need heavy thrust (10053 N push at 0.5 MPa) that exceeds the 6136 N capacity of a 125 mm bore. The adjustable stroke is ideal for variable end stops and machine setup, whereas a fixed SAI cylinder suits dedicated single-purpose stations. The robust 40 mm SUS304 rod handles high side loads, but at 225 mm stroke you should still guide the load externally.
To replace an ISO 15552 cylinder, match the 160 mm bore, 225 mm stroke, 75 mm adjustment, PT G3/4 port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting. Add an -S magnet if you need CMSE reed or DMSE electronic sensors.
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 SAIJ160BX225-75 FAQ
At 0.5 MPa, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At 0.7 MPa, the push force increases to 14074 N.
The rear adjuster acts as a stopper to shorten the effective travel. For this 225 mm stroke model, you can trim the retract position back by up to 75 mm, creating a usable 150 to 225 mm travel window.
