About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-20STC
The AirTAC SAIJ32X100-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 32 mm bore, a 100 mm nominal stroke, and a built-in magnet for position sensing. By turning the external stopper screw at the rear, you can trim the effective travel back by up to 20 mm, creating an 80-100 mm usable stroke window without needing external stops. In the compact 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This model incorporates a PT tapered port thread and a carbon steel piston rod. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to easily mount AirTAC CMSE reed or DMSE electronic solid-state switches along the body. The rear adjuster acts purely as a mechanical travel stop to fine-tune the retraction end position during commissioning; it does not lock the load or hold position without continuous live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-20STC Is Used
Machine Changeover
Dial in the 80-100 mm travel window during product size changes to perfectly position pick-and-place heads without swapping hardware.
End-Stop Calibration
Fine-tune the retraction end position during initial commissioning to compensate for mechanical tolerance stack-up in fixturing.
Sensor Targeting
Leverage the -S magnet and dual sensor grooves to mount DMSE solid-state switches exactly where the adjusted piston stops.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-20STC the Right Cylinder?
Choose this SAIJ32X100-20-S variant when your application requires precise end-position tuning during machine setup or product changeover, avoiding the need to physically swap out a fixed-stroke SAI cylinder. If your process demands greater thrust, stepping up to the 40 mm bore increases the push force to 628 N at 0.5 MPa, but the 32 mm bore is ideal for space-constrained assemblies. Because this is a 100 mm stroke, side-load risks are minimal, though the 12 mm rod diameter handles standard operational stresses effectively.
To match this exact ISO 15552 footprint for a direct replacement, verify the 32 mm bore, 100 mm stroke, 20 mm adjustment range, PT port thread, TC mounting accessory, and the -S magnet requirement. Remember that the adjustable stopper and the variable air cushions at both ends only manage deceleration; for true load-holding without live air, consider an external rod lock or the AirTAC SAIL pneumatic lock series.

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 SAIJ32X100-20STC FAQ
It features a rear mechanical stopper screw that allows you to shorten the 100 mm nominal stroke by up to 20 mm. This creates an adjustable 80-100 mm travel window, letting you set the exact retraction end position during setup without adding external stops.
Operating at 0.5 MPa, the SAIJ32X100-20-S generates 402 N of push force and 345 N of pull force. At its maximum rated pressure of 1.0 MPa, it can deliver up to 82 kgf of thrust.
