About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X155-30S
The AirTAC SAIJ160X155-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 155 mm stroke that can be fine-tuned down by up to 30 mm, yielding a usable travel window of 125-155 mm. This built-in adjustability allows operators to dial in exact retract end positions during commissioning without swapping hardware. Belonging to the 160 mm bore class, it generates 14074 N of push force and 9425 N of pull force at 0.7 MPa.
This variant includes a magnet (-S) for position sensing and uses a standard carbon steel piston rod. The extruded aluminum barrel features sensor grooves on both sides to accommodate AirTAC CMSE reed and DMSE electronic solid-state switches. It operates at speeds between 30-500 mm/s and relies on adjustable air cushions at both ends to decelerate heavy loads smoothly.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X155-30S Is Used
Heavy Press Tuning
Fine-tune the 125-155 mm retract position on heavy pressing equipment during setup, ensuring precise contact force without machining new stopper blocks.
Product Changeovers
Adapt diverter arms on a packaging line to different carton sizes by simply rotating the rear adjuster screw to shift the end position within the 30 mm window.
Machine Commissioning
Dial in the exact end-of-stroke location during initial machinery commissioning, compensating for mechanical tolerances without replacing the entire cylinder.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X155-30S the Right Cylinder?
Choose this 160 mm bore cylinder when an application requires substantial thrust, such as 14074 N push at 0.7 MPa, combined with variable end-stop positioning. If you need less force, stepping down to a 125 mm bore yields 8590 N of push force at the same pressure. The adjustable stroke is ideal for product-size changeovers on a line, providing a 125-155 mm travel window so you can reposition the retract stop without adding external spacers. For fixed-travel needs without commissioning tuning, the standard SAI series is a simpler alternative.
When specifying a replacement, verify the 155 mm stroke, 30 mm adjustment range, PT tapered port thread, and the -S magnet option. Mounting choices are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is 155 mm, side-load risks are moderate, but ensure adequate external guiding for heavy loads. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For true load-holding without pressure, consider the SAIL or BSAI series.
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 SAIJ160X155-30S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. At the maximum 1.0 MPa pressure, it achieves up to 18095 N of push force.
The rear adjuster screw allows you to shorten the 155 mm nominal stroke by up to 30 mm, creating a usable travel window of 125-155 mm. This stopper sets the retract end position but does not lock the load without continuous air pressure.
