About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-75
The AirTAC SAIJ160X180-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits you to trim the effective travel back by up to 75 mm. This yields a usable stroke window of 105 to 180 mm, allowing exact end-position calibration at commissioning without swapping out the unit or adding external stops. It delivers substantial thrust, offering 10053 N pull force at 0.5 MPa and 14074 N push force at 0.7 MPa.
The bore uses a robust 40 mm carbon steel rod with an M36x2 thread, which handles high side loads, though long unsupported travel still necessitates an external guide. It operates at 30-500 mm/s and includes variable air cushions at both ends. Note that the rear adjuster acts only as a travel stop for deceleration; it does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-75 Is Used
Press Stroke Calibration
Dial in the exact 105 to 180 mm travel window during press assembly to accommodate varying material thicknesses without changing cylinders.
Product Changeover
Quickly adjust the retract end-stop by up to 75 mm on a packaging line when switching to a different product size.
Heavy Fixture Positioning
Fine-tune the end position of heavy industrial fixtures during machine commissioning to ensure perfect alignment.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-75 the Right Cylinder?
Select this 160 mm bore when an application requires heavy force within the 10053 N to 18095 N range alongside variable end-stop positioning. If you need less force, stepping down to a 100 mm bore provides 3681 N pull at 0.5 MPa. Choose this adjustable SAIJ over a fixed-stroke SAI when you need on-the-fly stroke tuning during machine setup or product changeover. For load-holding without continuous air pressure, use an external rod lock or pilot-operated check valve, as the adjuster here is strictly a stop.
To match this ISO 15552 replacement exactly, specify: 160 mm bore, 180 mm stroke, 75 mm adjustment, PT tapered ports, and your preferred mounting from the reduced SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Since the total stroke is under 300 mm, side-load concerns are manageable, but the heavy 40 mm rod still benefits from a guide if subjected to lateral stresses.
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 SAIJ160X180-75 FAQ
At 0.5 MPa it provides 10053 N pull force and 14074 N push force at 0.7 MPa. The maximum push force is 18095 N at 0.9 MPa.
The rear adjuster screw lets you shorten the 180 mm nominal stroke by up to 75 mm, creating a usable travel range of 105 to 180 mm for fine-tuning end positions.
