About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX750-75
The AirTAC SAIJ32X750-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window from 675 to 750 mm. Delivering 402 N of push force at 0.5 MPa, it uses a PT G1/8 port and a 12 mm rod. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This SKU is built with a SUS304 stainless steel rod for superior corrosion resistance and packs adjustable air cushions at both ends. The 75 mm adjustment range lets you dial in the exact retract position during commissioning or product changeovers without swapping out the entire cylinder or adding bulky external stops.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX750-75 Is Used
Product Changeovers
Quickly dial in the 675 to 750 mm travel window during format changes on packaging lines without disassembling the actuator setup.
Variable End Stops
Set precise retract positions for pushing varying box sizes off a belt using the 75 mm rear adjustment screw.
Machine Setup
Fine-tune the end-of-stroke position during initial commissioning to avoid mechanical hard stops and reduce impact shock.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX750-75 the Right Cylinder?
Choose this 32 mm bore when you need precise end-position tuning combined with a long 750 mm travel, providing 345 N of pull force at 0.5 MPa. If your application requires significantly higher thrust, stepping up to the 40 mm bore yields 528 N of pull force. The integrated 75 mm rear stopper is ideal for variable end-stops on machines handling different product sizes. Because the stroke is 750 mm, the 12 mm rod and M10x1.25 thread may still experience side-loading forces, so an external guide is recommended to prevent rod binding.
This adjustable-stroke unit is dimensionally interchangeable with ISO 15552 cylinders and supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the rear adjuster and air cushions only decelerate the travel end; they do not hold the load without live air. For true load-holding without pressure, consider an external rod lock or the AirTAC SAIL or BSAI series.
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 SAIJ32BX750-75 FAQ
It delivers 402 N of push force and 345 N of pull force at 0.5 MPa, with a maximum operating pressure of 1.0 MPa. The operational speed range is 30-800 mm/s.
The rear adjuster acts as a stopper that lets you mechanically shorten the effective stroke from 750 mm down to 675 mm. It sets the travel end and works with the air cushions for deceleration, but it does not lock the load without live air pressure.
