About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX90-30
The AirTAC SAIJ160X90-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 60 to 90 mm, allowing you to dial back the 90 mm nominal stroke by up to 30 mm during commissioning. Belonging to the 160 mm bore class, it delivers substantial thrust, generating 14074 N of push force and 9425 N of pull force at a 0.7 MPa operating pressure.
This unit is configured with an SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic solid-state switches. Operating at speeds of 30-500 mm/s, it uses variable air cushions at both ends to decelerate the load smoothly.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX90-30 Is Used
Heavy Press Tuning
Dial in the exact 60-90 mm contact position on a heavy press during setup, avoiding the need to machine custom spacer blocks.
Product Changeover
Quickly adjust the end-stop distance on a packaging line when switching to a different product size, using the 30 mm trim range.
Assembly Station Setup
Fine-tune the retraction end-position of a heavy-duty assembly actuator at commissioning without swapping the entire cylinder.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX90-30 the Right Cylinder?
Select this model when an application requires heavy push force but the exact end-of-stroke position must be fine-tuned on-site without adding external physical stops. If you need less force, stepping down to a 100 mm bore yields 5497 N at 0.7 MPa; stepping up to a 200 mm bore provides 21991 N. The rear adjuster acts solely as a travel stop and cannot hold a load without live air pressure—use an SAIL air-released lock or BSAI clamp-lock cylinder if fail-safe load holding is required.
This SAIJ160X90-30 is dimensionally interchangeable per ISO 15552 mounting-interface dimensions. It supports a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because this is a short 90 mm stroke, side-loading risks are minimal, but the robust 40 mm rod and M36x2 thread handle high mechanical stress well.

- ✓ 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 SAIJ160AX90-30 FAQ
At 0.7 MPa, this 160 mm bore cylinder provides a push force of 14074 N and a pull force of 9425 N. It can deliver a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster screw lets you shorten the 90 mm nominal stroke by up to 30 mm, creating a usable travel window of 60 to 90 mm. This allows precise end-position tuning at commissioning without external stops.
