About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX75-30
The AirTAC SAIJ160X75-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing the effective travel to be fine-tuned within a 45 to 75 mm window. It delivers substantial thrust, providing 18095N of push force at 0.9 MPa, making it well-suited for heavy-duty positioning tasks. The extruded aluminum barrel features sensor grooves on both sides for straightforward detection integration.
This configuration features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threading. The rear adjuster functions strictly as a mechanical stop to set the end position during commissioning; it is not a locking device and cannot hold the load without continuous live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX75-30 Is Used
Heavy-Duty Pressing
Delivers 18095N of thrust at 0.9 MPa for securely seating large bearings or heavy components during precision assembly operations.
Machine Changeover
The 30 mm rear adjustment window allows operators to quickly reconfigure end-stops for varying product sizes on a single production line.
Clamping Fixtures
Provides robust, repeatable clamping force on large industrial workpieces where exact end-position tuning is critical for part integrity.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX75-30 the Right Cylinder?
Choose this 160 mm bore when your application requires significantly more force than a 125 mm bore, which provides 11045N of push force at 0.9 MPa. The adjustable stroke is ideal for machine setups requiring variable end-stops or product-size changeovers without physically swapping out the entire cylinder for a fixed-stroke SAI variant. Because the stroke is 75 mm, no external side-load guide is strictly necessary, but the robust 40 mm rod and M36x2 thread handle high mechanical stress well.
If your application demands fail-safe load holding without constant air pressure, this cylinder's adjuster and air cushions will not suffice; consider an AirTAC SAIL air-released lock, a BSAI clamp-lock, or an external pilot-operated check valve instead. This model is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting interfaces.
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 SAIJ160BX75-30 FAQ
At an operating pressure of 0.9 MPa, this 160 mm bore cylinder generates a push force of 18095N and a pull force of 9425N. The maximum allowable operating pressure is 1.0 MPa.
The rear adjuster acts as a mechanical stop, allowing you to shorten the nominal 75 mm stroke by up to 30 mm, creating a usable travel window of 45 to 75 mm. It only sets the end position and does not lock the load without live air pressure.
