About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX220-50S
The AirTAC SAIJ32X220-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 402N of push force at 0.5 MPa and features a 12mm SUS304 stainless steel rod. The built-in adjuster allows you to trim the effective travel back by up to 50mm, providing a usable stroke window of 170-220mm for precise end-position tuning during commissioning.
This adjustable-stroke variant utilizes a PT tapered port thread and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides. The rear stopper mechanism sets the travel end and relies on the variable air cushion for deceleration, but it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX220-50S Is Used
Product Changeover
Dial in the 170-220mm travel window instantly on the rear screw when switching between product sizes on a packaging line, avoiding mechanical rebuilds.
End-Position Tuning
Fine-tune the exact retract stop during machine commissioning to perfect alignment without fabricating custom external spacers.
Sensor Equipped Feedback
Leverage the integrated magnet with DMSE electronic sensors to confirm the adjusted end-of-stroke position in automated control systems.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX220-50S the Right Cylinder?
Choose this 32mm bore when an application requires fine-tuning of the retract end-position without swapping cylinders or adding external stops. If your setup demands greater thrust, stepping up to the 40mm bore yields 628N of push force at 0.5 MPa. The -S magnet enables direct mounting of CMSE and DMSE switches for position feedback.
Because the nominal stroke is 220mm, the 12mm rod may still experience side-loading if the load is unsupported; an external guide is recommended for optimal longevity. The rear adjuster acts purely as a travel stop, not a lock, so load-holding without live air requires a SAIL or BSAI cylinder. For ISO 15552 replacement matching, specify the 32mm bore, 220mm stroke, 50mm adjustment, PT port, and the desired mounting set (Basic, FA, LB, TC, FTC, TCM1, or TCM2).

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 SAIJ32BX220-50S FAQ
The rear adjuster acts as an external stopper that lets you shorten the nominal 220mm stroke by up to 50mm. This creates a usable travel window of 170-220mm, allowing you to set the exact retract position at commissioning without changing the cylinder.
At 0.5 MPa operating pressure, the SAIJ32X220-50-S provides 402N of push force and 345N of pull force. It can reach a maximum push force of 724N at 0.9 MPa.
