About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX135-100S
The AirTAC SAIJ32X135-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 100 mm. This creates a highly flexible 35-135 mm usable window on a 135 mm nominal stroke, perfect for dialing in exact end positions during machine commissioning. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This variant is equipped with a SUS304 stainless steel rod (option B) for superior corrosion resistance and includes a magnet for position sensing. It is compatible with AirTAC CMSE reed switches and DMSE solid-state electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the unit utilizes a PT tapered port thread alongside an M10x1.25 rod thread.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX135-100S Is Used
Machine Commissioning
Dial in the exact 35-135 mm end position during setup without machining external spacers or changing the cylinder.
Product Changeover
Quickly adapt the travel window on packaging lines when switching between different package sizes.
Variable End Stops
Use the rear screw to set precise retract stops for light-duty clamping or positioning tasks.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX135-100S the Right Cylinder?
Choose this adjustable model over a fixed SAI when your application requires variable end-stops or frequent product-size changeovers, as the rear screw stopper fine-tunes the travel end without swapping the cylinder or adding external stops. If you need greater thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. To replace an ISO 15552 cylinder, match the 32 mm bore, 135 mm stroke, 100 mm adjustment, PT G1/8 port, and the -S magnet.
Because the nominal stroke is 135 mm, the 12 mm rod diameter handles moderate side loads, though long unsupported strokes still require an external guide. Note that the rear adjuster acts only as a travel stop and the air cushions provide deceleration; neither will hold a load without live air. For true load-holding without pressure, consider the SAIL or BSAI series. SAIJ uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
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 SAIJ32BX135-100S FAQ
The rear adjuster screw acts as a mechanical stopper that lets you shorten the 135 mm nominal stroke by up to 100 mm, providing a usable travel window of 35-135 mm. It is a travel stop, not a lock, and does not hold the load without live air pressure.
At 0.5 MPa, the 32 mm bore provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
