About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX75-50
The AirTAC SAIJ160X75-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel within a 25-75 mm window. It delivers massive thrust, providing 14074N of push force and 9425N of pull force at 0.7 MPa. This bore size uses a G3/4 port and includes variable air cushions at both ends to manage heavy kinetic energy.
This specific SKU is built with a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing for direct mounting of CMSE reed or DMSE electronic sensors if position feedback is later required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX75-50 Is Used
Heavy Press Tuning
Dial in the exact 25 to 75 mm pressing distance during commissioning to accommodate different material thicknesses without swapping out the entire cylinder.
Machine Changeover
Quickly adjust the retract end-stop when switching a production line to a new product size, saving hours of mechanical retooling time.
Robust Assembly Station
Leverage the 14074N push force at 0.7 MPa and SUS304 rod to drive heavy-duty joining operations while resisting washdown environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX75-50 the Right Cylinder?
Choose this 160 mm bore when an application demands high force that a 125 mm bore cannot provide, as stepping down to 125 mm drops the 0.5 MPa push force to 6136N. The 50 mm adjustment range is ideal for machine changeovers, letting you dial in the exact end position without adding external stops. If you need to hold a load without live air pressure, note that the rear adjuster is only a travel stop, not a lock; you should look at the SAIL or BSAI series for secure load-holding. When replacing an ISO 15552 cylinder, match the 160 mm bore, 75 mm stroke, PT G3/4 port, and your required mounting style from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2.
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 SAIJ160BX75-50 FAQ
At 0.7 MPa, this 160 mm bore cylinder generates 14074N of push force and 9425N of pull force. It can deliver a maximum push force of 18095N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that lets you trim the nominal 75 mm stroke back by up to 50 mm, providing an effective usable travel window of 25 to 75 mm. It functions as a stop to tune end positions, not as a lock to hold the load without air pressure.
