About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-30S
The AirTAC SAIJ32X100-30-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, letting you dial the effective travel back by up to 30 mm to create a 70-100 mm usable stroke window. It delivers 402 N of push force at 0.5 MPa and features a SUS304 stainless steel piston rod for superior corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches.
This adjustable variant eliminates the need to physically swap the cylinder or bolt on external stops when fine-tuning end positions during machine commissioning. It uses a PT tapered port thread and provides variable air cushioning at both ends to decelerate the load smoothly. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-30S Is Used
Changeover Positioning
Dial in the 70-100 mm travel window during product size changeovers on a packaging line without swapping out the entire actuator.
Commissioning End-Stop
Fine-tune the retract position during machine setup to hit the exact datum point, using the rear screw instead of adding external mechanical stops.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for light-duty clamping or pushing tasks in environments where standard carbon steel rods would rust.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-30S the Right Cylinder?
Choose this 32 mm bore when you need precise retract-end tuning and moderate force, stepping up to a 40 mm bore (528 N pull at 0.5 MPa) only if your payload exceeds the 402 N push capacity. The 30 mm adjustment window is ideal for product changeovers on a line where the exact end position varies slightly. For a fixed end position without the need for commissioning tweaks, a standard SAI cylinder is simpler. To hold a load statically without continuous air pressure, use an external rod lock or pilot-operated check valve, as the SAIJ adjuster and air cushions are not locking devices.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 100 mm nominal stroke, 30 mm adjustment range, PT port thread, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. The 12 mm piston rod and M10x1.25 thread handle standard loads well, but long unsupported strokes still require an external guide to prevent side-load wear.

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 SAIJ32BX100-30S 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 delivers up to 82 kgf.
A rear adjusting screw acts as a mechanical stopper, allowing you to shorten the 100 mm nominal stroke by up to 30 mm. This creates a 70-100 mm adjustable travel window for fine-tuning the end position without replacing the cylinder.
