About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-100
The AirTAC SAIJ32X100-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel anywhere within a 0-100 mm window. Equipped with a 12 mm carbon steel rod and a PT G1/8 port, it delivers 402 N of push force at 0.5 MPa. This makes it well-suited for compact setups where the exact end-of-stroke position must be dialed in at commissioning without adding external stops.
Because the adjuster acts purely as a mechanical stop, it decelerates the travel end but does not hold the load without live air pressure. The extruded aluminum barrel includes sensor grooves on both sides, ready to accept CMSE reed or DMSE electronic switches if a magnet is specified later. It uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR options found on some fixed-stroke variants.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-100 Is Used
Prototype Tooling
Dial in the exact clamping distance during R&D by trimming the stroke from 100 mm down to near zero, avoiding the need to swap cylinders for every new jig.
Machine Changeover
Quickly adjust the retract end-position by up to 100 mm when switching between product sizes on a packaging line, saving hours of mechanical retooling.
Variable End-Stop
Use the rear screw to set a precise, repeatable travel limit for delicate positioning tasks without installing bulky external shock absorbers.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-100 the Right Cylinder?
Choose this 32 mm bore when you need 402 N of thrust at 0.5 MPa but anticipate frequent product changeovers requiring a variable end-stop. If your application demands less force, stepping down is not an option in this size range, but stepping up to a 40 mm bore yields 628 N. The massive 100 mm adjustment range on a 100 mm nominal stroke means you can effectively reduce the travel to near zero, offering unmatched flexibility for prototype tooling or short-stroke clamping where a fixed 100 mm SAI cylinder would be too long.
For any load-holding requirements without continuous air pressure, note that this rear adjuster is not a lock. You would need to look at the SAIL (air-released lock) or BSAI (clamp-lock) series instead. When replacing an ISO 15552 cylinder, match the 32 mm bore, 100 mm stroke, PT G1/8 port, and the desired mounting accessory. Given the 100 mm stroke, side-load is minimal, but always ensure the 12 mm rod is guided if pushing off-center.

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 SAIJ32X100-100 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 100 mm. Because the nominal stroke is 100 mm, you can tune the usable travel anywhere from 0 to 100 mm. The adjuster acts as a mechanical stop to set the end position and does not lock the load without air pressure.
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. If you increase the operating pressure to 0.7 MPa, the push force rises to 563 N.
