About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX185-10S
The AirTAC SAIJ32X185-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 10 mm trim range, creating a 175-185 mm usable travel window for exact end-position calibration. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod and includes a magnet for position sensing.
This model utilizes a PT tapered port (G1/8) and features an extruded aluminum barrel with sensor grooves on both sides. The rear adjustment screw allows you to fine-tune the retract position during commissioning without adding external stops. It supports AirTAC CMSE reed and DMSE electronic sensors, while the adjustable stop and standard air cushions decelerate the stroke but do not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX185-10S Is Used
Changeover Calibration
Dial in the exact 175-185 mm retract position during machine changeovers without swapping out the entire cylinder.
End-Stop Tuning
Fine-tune the final position of a tooling head by up to 10 mm at commissioning to avoid mechanical binding.
Variable Product Stops
Adjust the physical stop location on a conveyor line to accommodate slightly different product lengths on the fly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX185-10S the Right Cylinder?
Choose this 32 mm bore when an application requires 402 N push force at 0.5 MPa with a highly specific end-stop. If your setup needs less force, stepping down is not an option in this series, but stepping up to a 40 mm bore yields 628 N. The 10 mm adjustment window is perfect for dialing in a 175-185 mm stroke during product changeovers. Because the rear screw is a travel stop and not a locking device, use a SAIL or BSAI cylinder if the load must be held without continuous air pressure.
To replace an ISO 15552 cylinder, match the 32 mm bore, 185 mm stroke, PT G1/8 port, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. At 185 mm, the stroke is moderate, but always ensure proper guiding to prevent excessive side-loading on the 12 mm rod.
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 SAIJ32BX185-10S FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 185 mm nominal stroke by up to 10 mm. This creates a 175-185 mm usable travel window for fine-tuning the end position without changing the cylinder.
At 0.5 MPa operating pressure, the SAIJ32X185-10-S provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 82 kgf.
