About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX40-10S
The AirTAC SAIJ32X40-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 30-40 mm usable travel window from the 40 mm nominal stroke. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa, making it well-suited for compact, lower-force tasks. The extruded aluminum barrel includes sensor grooves on both sides for straightforward switch placement.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and integrates a magnet for position sensing with CMSE reed and DMSE electronic switches. It features PT tapered port threads (G1/8) and offers adjustable air cushions at both ends. The rear adjuster acts purely as a mechanical stop to fine-tune the retract position, meaning it will not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX40-10S Is Used
End-Stop Tuning
Dial in the exact retract position within a 30-40 mm window during machine commissioning without installing external physical stops.
Product Changeover
Quickly adapt the cylinder's effective stroke on packaging lines when handling slightly different product sizes on the fly.
Compact Positioning
Leverage the 402 N thrust and SUS304 rod for precise, corrosion-resistant component positioning in tight assemblies.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX40-10S the Right Cylinder?
Choose this 32 mm bore model when your application requires 402 N of thrust at 0.5 MPa; if you need more force, stepping up to the 40 mm bore yields 628 N. The adjustable stroke is ideal for machine setup and product changeovers, allowing you to dial in the end-position by up to 10 mm without adding external stops or swapping out a fixed-stroke SAI cylinder. For load-holding without continuous air pressure, consider an external pilot-operated check valve or the SAIL lock series. To match this cylinder for an ISO 15552 replacement, specify the 32 mm bore, 40 mm stroke, 10 mm adjustment, PT G1/8 port, and the -S magnet.

- ✓ 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 SAIJ32BX40-10S FAQ
At a 0.5 MPa operating pressure, 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 screw lets you shorten the effective travel from the 40 mm nominal stroke down to 30 mm, creating a 30-40 mm adjustable window. This stop only sets the end position; it does not lock or hold the load without live air pressure.
