About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX750-75S
The AirTAC SAIJ160X750-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the effective travel back by up to 75 mm. This creates a usable stroke window of 675 to 750 mm, allowing precise end-position tuning at commissioning without swapping the barrel or adding external stops. Equipped with a 40 mm SUS420J2 stainless steel rod, it delivers robust thrust up to 18095 N at 0.9 MPa.
Built with an extruded aluminum barrel and sensor grooves on both sides, this unit includes a magnet for CMSE and DMSE switches. The rear adjuster acts purely as a travel stop to decelerate the load alongside the 50 mm air cushions, but it does not hold the load without live air. For position holding, consider an external rod lock or SAIL series cylinder.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX750-75S Is Used
Heavy Press Tuning
Dial in the exact 675 to 750 mm end-stop for large stamping or press operations without machining custom external spacers.
Product Changeover
Quickly adjust the retract position on a conveyor sorting line when handling different sized heavy pallets or packages.
Assembly Line Setup
Fine-tune the clamping position of large components during machine setup to compensate for material thickness variations.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX750-75S the Right Cylinder?
Choose this 160 mm bore when your application requires heavy thrust in the 18095 N range at 0.9 MPa, stepping up from a 125 mm bore that provides 11045 N. The adjustable 675 to 750 mm window is ideal for product changeover on a line, letting you fine-tune the retract end without external stoppers. If your force needs are lower, a 100 mm bore offers 7068 N.
Because the 750 mm stroke is long and unsupported, an external guide is recommended to manage side loading on the 40 mm rod and M36x2 thread. As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with standard mounting interfaces using a PT tapered G3/4 port. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, and the included magnet works with electronic DMSE and reed CMSE switches.
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 SAIJ160 Adjustable Cylinder SAIJ160AX750-75S FAQ
At 0.9 MPa, this 160 mm bore cylinder provides a push force of 18095 N and a pull force of 9425 N. The maximum push force is 10053 N at 0.5 MPa.
The rear adjuster allows you to shorten the 750 mm nominal stroke by up to 75 mm, giving an effective travel window of 675 to 750 mm. The adjuster is a mechanical stop, not a lock, so it cannot hold the load without live air pressure.
