About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X115-100S
The AirTAC SAIJ32X115-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel. With a nominal 115 mm stroke and a 100 mm adjustment range, it provides a wide usable travel window of 15 to 115 mm. Delivering 402 N of push force at 0.5 MPa, it is dimensionally interchangeable with ISO 15552 cylinders without relying on tie-rod construction.
The integrated -S magnet supports position sensing via AirTAC CMSE reed or DMSE electronic switches fitted into the dual-side sensor grooves. The rear adjuster acts purely as a travel stop to decelerate the piston, meaning it will not hold a load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X115-100S Is Used
Product Changeover
Dial the stroke from 115 mm down to 15 mm during product size changes on a packaging line without swapping the cylinder or adding external stops.
End-Position Tuning
Fine-tune the retract end position at machine commissioning to perfect a gripping or pressing operation, using the rear screw to absorb kinetic energy.
Variable End Stops
Establish a highly flexible travel window for automated test fixtures where the contact point shifts based on the specific component being validated.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X115-100S the Right Cylinder?
Choose this 32 mm bore when an application requires 402 N of push force at 0.5 MPa and highly variable end-position tuning. If your setup needs less force, stepping down is not an option in this bore range, but stepping up to a 40 mm bore yields 628 N. The massive 100 mm adjustment window on a 115 mm stroke allows you to dial the travel back to as little as 15 mm, making it highly effective for machine changeovers where product sizes vary dramatically.
Because the stroke is 115 mm, an external guide is recommended to manage side loads. To match this replacement exactly: specify a 32 mm bore, 115 mm stroke, 100 mm adjustment, PT tapered port thread, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ32X115-100S FAQ
The rear adjuster screw lets you shorten the nominal 115 mm stroke by up to 100 mm, creating a usable travel window of 15 to 115 mm. The adjuster acts as an external stop to set the end position and does not lock the load without live air pressure.
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It operates at speeds between 30 and 800 mm/s.
