About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-40S
The AirTAC SAIJ32X100-40-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. Equipped with a magnet for position sensing, it operates reliably with CMSE reed and DMSE electronic solid-state switches. The carbon steel piston rod and PT tapered port threads ensure robust performance for standard pneumatic setups.
This model provides a 60-100 mm usable travel window by allowing you to trim the 100 mm nominal stroke back by up to 40 mm. Delivering 402 N of push force at 0.5 MPa, it utilizes a 27 mm air cushion at both ends to decelerate the load smoothly. The rear adjuster acts purely as a mechanical stop to fine-tune the end position, meaning it cannot hold a load without continuous live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-40S Is Used
Machine Changeovers
Quickly adapt the 60-100 mm travel window during product size transitions on a packaging line without disassembling the cylinder mounting.
Variable End Stops
Fine-tune the retract position at commissioning using the rear screw, perfect for testing different sensor trigger points on a prototype.
Light-Duty Positioning
Move small jigs with 402 N of force at 0.5 MPa, relying on the external stopper to set the exact resting coordinates for a delicate assembly process.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-40S the Right Cylinder?
Choose this 32 mm bore cylinder when your application requires 402 N of push force at 0.5 MPa and precise end-position tuning without swapping hardware. The adjustable stroke is ideal for machine changeovers, allowing you to dial in the travel window quickly. If you need to step up to 628 N of push force, consider the 40 mm bore neighbor. Since this is a 100 mm stroke, side-loading is minimal, but always ensure axial alignment. For applications requiring true load-holding without live air, select the SAIL (air-released lock) or BSAI (clamp-lock) series instead, as the SAIJ rear stopper is not a brake. To match this ISO 15552 footprint exactly, specify the 32 mm bore, 100 mm stroke, 40 mm adjustment, PT port, and -S magnet.

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 SAIJ32X100-40S FAQ
It features a rear adjusting screw that lets you shorten the effective travel from the 100 mm nominal stroke down by up to 40 mm, creating a 60-100 mm usable window. The adjuster acts as a mechanical stop and does not lock the load without live air pressure.
It provides 402 N of push force and 345 N of pull force at 0.5 MPa, reaching up to 724 N push at 0.9 MPa. The operating speed ranges from 30 to 800 mm/s.
