About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX195-75
The AirTAC SAIJ32X195-75 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 120 to 195 mm, allowing you to dial back the nominal 195 mm stroke by up to 75 mm during commissioning without adding external stops. In the 32 mm bore class, it delivers a 0.7 MPa push force of 563 N and a pull force of 1402 N at 1.0 MPa.
This variant is configured with a SUS420J2 stainless steel piston rod (option A) for enhanced corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is specified without a magnet, meaning electronic DMSE or reed CMSE position sensing cannot be utilized without a rod magnet. It relies on variable air cushions at both ends (27 mm cushion length) to decelerate the load.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX195-75 Is Used
Product Changeover
Dial in the 120-195 mm travel window on the fly when swapping product sizes on a packaging line, eliminating the need to physically swap out the entire cylinder.
End-Position Tuning
Fine-tune the exact retract position during machine commissioning using the rear stopper, hitting precise mechanical endpoints without external shims.
Machine Setup
Adjust the stroke down by up to 75 mm to synchronize multi-cylinder movements during initial assembly and setup of automated equipment.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX195-75 the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when your machine setup requires precise end-position tuning across product changeovers, rather than relying on a fixed-stroke SAI cylinder. If your application demands higher thrust, stepping up to the 40 mm bore yields a 0.5 MPa push force of 628 N. The rear adjuster screw acts strictly as a travel stop and does not hold the load without live air pressure; for true load-holding without continuous air, consider the SAIL or BSAI series. For a direct ISO 15552 replacement match, ensure you specify the 32 mm bore, 195 mm nominal stroke, 75 mm adjustment range, PT port threads, and the SUS420J2 rod material. Because the stroke is under 300 mm, side-load stress on the 12 mm rod is manageable, but an external guide is still recommended for heavy lateral loads.

- ✓ 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 SAIJ32AX195-75 FAQ
At a 0.7 MPa operating pressure, this 32 mm bore cylinder provides a push force of 563 N and a pull force of 345 N at 0.5 MPa. The maximum push force is 724 N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from the 195 mm nominal down to as little as 120 mm. It decelerates the travel end but does not lock or hold the load without continuous air pressure.
