About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX275-100
The AirTAC SAIJ160X275-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 175 to 275 mm, allowing you to dial back the nominal 275 mm stroke by up to 100 mm during commissioning. Equipped with a SUS304 stainless steel rod, it delivers robust thrust, generating 14074 N of push force at 0.7 MPa.
This bore size uses a G3/4 port and includes 50 mm of variable air cushioning at both ends to manage heavy kinetic energy. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible positioning feedback. You can fine-tune the retract end position directly without adding external stops or changing the cylinder body.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX275-100 Is Used
Heavy Press Tuning
Dial in the exact 175 to 275 mm end-position for large pressing operations without swapping out the entire actuator.
Product Changeover
Quickly adjust the retract stop for different product sizes on a high-thrust assembly line during scheduled setup changes.
Heavy Load Positioning
Move substantial masses using the 14074 N push force at 0.7 MPa while relying on the 50 mm cushions to absorb impact energy.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX275-100 the Right Cylinder?
Choose this 160 mm bore when your application requires significantly more force than the 125 mm size, which yields 8590 N of push at 0.7 MPa. The 100 mm adjustment range is ideal for product changeovers where the end-stop position shifts frequently. For load-holding without live air pressure, this cylinder's adjuster acts only as a travel stop, so you would need to specify a SAIL or BSAI series instead. When replacing an ISO 15552 cylinder, match the 160 mm bore, 275 mm stroke, G3/4 PT ports, and the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting set. Because the stroke is 275 mm, ensure an external guide supports the load to prevent rod side-loading.
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 SAIJ160BX275-100 FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates 14074 N of push force and 9425 N of pull force. It can reach a maximum push force of 18095 N at 0.9 MPa.
A rear external screw stopper lets you shorten the effective travel from the 275 mm nominal stroke down to a minimum of 175 mm. This stopper sets the retract end position but does not lock or hold the load without continuous air pressure.
