About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX160-75S
The AirTAC SAIJ32X160-75-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 160 mm stroke that can be dialed back by up to 75 mm, creating an 85-160 mm usable travel window for precise end-position tuning. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and operates at speeds of 30-800 mm/s. The integrated magnet supports AirTAC CMSE reed and DMSE electronic sensors, fitting neatly into the dual-side sensor grooves of the extruded aluminum barrel. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX160-75S Is Used
Product Changeovers
Dial in the 85-160 mm travel window during format changes on packaging lines, avoiding the need to physically swap cylinders for different package sizes.
Machine Setup
Fine-tune the retract end-position at commissioning to perfectly mate tooling, absorbing mechanical tolerances without adding external stop blocks.
Variable End Stops
Provide adjustable positioning for testing fixtures, allowing operators to modify the stroke length on the fly based on the specific component being tested.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX160-75S the Right Cylinder?
Select this adjustable model when your application requires variable end-stops or frequent product changeovers without swapping the entire cylinder. If you need higher force, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. The rear adjuster acts purely as a mechanical stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series. For a direct ISO 15552 replacement, match the 32 mm bore, 160 mm stroke, 75 mm adjustment, PT ports, SUS304 rod, and -S magnet.
Because the stroke is 160 mm, the 12 mm rod and M10x1.25 thread handle moderate side loads, but an external guide rail is recommended for heavy off-center loads to prevent premature seal wear.
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 Adjustable Cylinder SAIJ32 SAIJ32BX160-75S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum operating pressure of 1.0 MPa, it achieves a push force of 82 kgf.
The rear adjuster screw allows you to trim the effective stroke by up to 75 mm from the nominal 160 mm, providing an adjustable travel window of 85 to 160 mm. This stopper only sets the end position and does not lock the load without air pressure.
