About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-100S
The AirTAC SAIJ32X210-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 210 mm travel back by up to 100 mm, creating a wide 110 to 210 mm usable window. Delivering 402 N of push force at 0.5 MPa, it uses a SUS304 stainless steel rod for corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors.
This model uses PT tapered port threads and relies on its built-in variable air cushions alongside the mechanical stopper to decelerate the load. The rear adjuster functions purely as a travel stop and does not lock the load without live air pressure, so a SAIL or BSAI variant is needed for true load-holding.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-100S Is Used
Product Changeover Stops
Dial in the exact end position from 110 to 210 mm when switching a packaging line to a different carton size without changing the cylinder.
Machine Setup Tuning
Fine-tune the retract end-stop during commissioning to perfect the pick-and-place depth before locking down the sequence.
Variable Test Travel
Iteratively shorten the stroke in a test fixture to find the optimal engagement distance for a new sensor or actuator prototype.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-100S the Right Cylinder?
Select this 32 mm bore cylinder when an application requires a 110 to 210 mm stroke range but you want to avoid bolting on external stops or swapping cylinders during product changeover. If your process demands higher force, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. To match this ISO 15552 footprint, specify a 32 mm bore, 210 mm stroke, 100 mm adjustment, PT ports, and the -S magnet option.
Because the total travel reaches 210 mm, ensure adequate external guidance to prevent side-loading on the 12 mm rod. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR brackets.
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 SAIJ32BX210-100S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the 210 mm nominal stroke by up to 100 mm, yielding a usable travel window of 110 to 210 mm. It only sets the end position and does not hold the load without live air.
