About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX115-75
The AirTAC SAIJ32X115-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 115 mm travel back by up to 75 mm, creating a highly flexible 40-115 mm usable window. Delivering 402 N of push force at 0.5 MPa, it suits lighter-duty tasks requiring exact end-position tuning without external stops. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position feedback.
This variant is built with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The rear adjuster functions strictly as a travel stop for commissioning and product changeovers; it does not hold the load without live air pressure. For position-holding needs, a SAIL or BSAI variant would be required.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX115-75 Is Used
Variable End-Stop Tuning
Dial in the exact 40-115 mm travel window during machine commissioning without swapping cylinders or adding bulky external physical stops.
Product Changeover
Quickly adjust the retract end-position on packaging lines when handling different product sizes, using the rear screw to set new limits.
Light-Duty Positioning
Leverage the 402 N push force at 0.5 MPa for precise low-force assembly tasks, relying on the rear stopper for repeatable end-point tuning.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX115-75 the Right Cylinder?
Choose this 32 mm bore when your application needs 402 N of thrust at 0.5 MPa (or 724 N at 0.9 MPa) but demands a variable end-stop within a 40-115 mm range. If your setup requires higher force, stepping up to the 40 mm bore yields 628 N at 0.5 MPa. Conversely, lighter duties might warrant a smaller frame. The adjustable stroke is selected over a fixed SAI cylinder when you need on-the-fly fine-tuning during machine commissioning or product size changeovers.
As an ISO 15552 profile cylinder, it ensures dimensional interchangeability with standard mounting interfaces. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because it lacks a magnet (-S), it does not support AirTAC CMSE reed or DMSE electronic sensors natively. Remember that the rear adjuster only sets the travel end and deceleration; it is not a lock or brake.
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 SAIJ32BX115-75 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. At 0.9 MPa, the push force increases to 724 N.
The rear adjuster allows you to shorten the nominal 115 mm stroke by up to 75 mm, providing a usable travel window of 40 to 115 mm. The adjuster acts as a stop to set the end position and does not lock the load without air pressure.
