About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX195-75S
The AirTAC SAIJ32X195-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the nominal 195 mm stroke by up to 75 mm. This yields a usable travel window of 120 to 195 mm, providing exact end-position tuning at commissioning without swapping hardware. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa, fitting compact pneumatic setups. The extruded aluminum barrel includes sensor grooves on both sides, and this -S variant includes a magnet ready for CMSE reed and DMSE solid-state switches.
This model uses a 12 mm stainless steel (SUS304) piston rod with an M10x1.25 thread, paired with PT tapered ports. The rear adjuster acts purely as a mechanical stop to set the travel end and deceleration point alongside the standard air cushions; it is not a lock and cannot hold a load without live air pressure. For true fail-safe load holding, consider the SAIL or BSAI series instead. Mounting options cover the standard SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX195-75S Is Used
Machine Changeover
Dial in the 120-195 mm travel window during product size changes on a packaging line without adding external stops.
End-Position Tuning
Fine-tune the exact retract position at commissioning using the rear adjuster to perfect the pickup location.
Sensor Integration
Leverage the integrated magnet for CMSE or DMSE switches to confirm the adjusted end-stroke in automated assembly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX195-75S the Right Cylinder?
Choose this 32 mm bore when your application requires the 402 N push force at 0.5 MPa, stepping down from a 40 mm bore (628 N) to save space, or up from a smaller body. An adjustable stroke is selected over a fixed SAI cylinder when you need variable end-stops for machine changeover or product-size adjustments, allowing you to fine-tune the 120-195 mm travel window on the fly. To match this cylinder for an ISO 15552 replacement, specify the 32 mm bore, 195 mm stroke, 75 mm adjustment, PT G1/8 port, and the -S magnet. Because the stroke is under 300 mm, side-load concerns are minimal, but always ensure the rod thread is properly aligned.
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 SAIJ32BX195-75S FAQ
At 0.5 MPa it provides 402 N push and 345 N pull force, reaching 724 N push at 0.9 MPa. The operating speed range is 30-800 mm/s.
The rear adjuster is a mechanical stop that lets you trim the 195 mm nominal stroke back by up to 75 mm, creating a 120-195 mm usable travel window. It sets the end position but does not lock the load without air pressure.
