About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX80-30S
The AirTAC SAIJ160X80-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 80 mm travel by up to 30 mm. This creates a highly specific 50-80 mm usable stroke window, perfect for fine-tuning end positions during machine commissioning without swapping out the physical actuator. Built with a SUS304 stainless steel rod and PT tapered ports, it handles heavy loads with a push force of 10053 N at 0.5 MPa.
Because this is a profile cylinder, the extruded aluminum barrel features sensor grooves on both sides. The included magnet (-S) directly supports AirTAC CMSE reed and DMSE electronic solid-state switches for precise position feedback. The rear adjuster acts purely as a travel stop for end-position tuning and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX80-30S Is Used
Heavy Press Tuning
Dial in the exact 50-80 mm end-of-stroke position during heavy press commissioning to accommodate varying material thicknesses without changing the actuator.
Product Size Changeover
Rapidly adjust the travel stop on automated packaging lines when switching between different pallet or product dimensions on the fly.
Variable End Stops
Establish precise mechanical end limits for heavy-duty assembly stations, utilizing the 10053 N pull force to secure and manipulate substantial tooling.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX80-30S the Right Cylinder?
Selecting this 160 mm bore actuator provides massive thrust, stepping up significantly from the 125 mm bore which yields 6136 N of push force at 0.5 MPa. The adjustable stroke is chosen when a machine requires variable end-stops for rapid product-size changeovers, avoiding the need to bolt on external stops or purchase a fixed-stroke SAI cylinder. For load-holding applications without continuous live air, a plain SAIJ is insufficient since the rear adjuster is a stop, not a lock; you should instead look at the SAIL or BSAI series, or employ an external pilot-operated check valve.
To guarantee a true ISO 15552 replacement match, verify the 160 mm bore, 80 mm nominal stroke, 30 mm adjustment range, PT port threads, and the -S magnet. The standard SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Although the stroke is short, the robust 40 mm rod and M36x2 thread handle substantial side loads, though any long unsupported tooling should still utilize an external guide.

- ✓ 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 SAIJ160BX80-30S FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides a push force of 10053 N and a pull force of 9425 N. At the maximum 1.0 MPa pressure, it achieves a push force of 20000 N.
The rear adjuster screw allows you to shorten the 80 mm nominal stroke by up to 30 mm, creating a usable travel window of 50-80 mm. This stopper fine-tunes the retracted end position but does not lock the load without live air pressure.
