About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX115-30S
The AirTAC SAIJ160X115-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 85 to 115 mm. The extruded aluminum barrel features sensor grooves on both sides, and this unit includes a magnet for position detection via CMSE reed or DMSE electronic switches.
This model features a SUS304 stainless steel rod and PT tapered port threads. The rear adjuster acts strictly as a mechanical stop for end-position tuning during commissioning; it does not hold the load without live air pressure. For applications requiring true load-holding, consider the SAIL or BSAI series instead.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | — |
| Max (@1.0 MPa) | 1922 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX115-30S Is Used
Heavy Press Tuning
Dial in the 85-115 mm travel window during heavy press commissioning to achieve exact end-position contact without adding external mechanical stops.
Product Changeover
Quickly adjust the rear stopper on automated assembly lines when switching between product variants that require slightly different stroke endpoints.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX115-30S the Right Cylinder?
Select this 160 mm bore cylinder when your application requires high force and precise end-stop tuning without swapping components. If your setup needs less force, stepping down to a 125 mm bore yields 5734 N of pull force at 0.5 MPa. The adjustable stroke is ideal for machine changeovers, allowing you to dial in the exact 85-115 mm travel window on the fly rather than machining external stops.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 115 mm stroke, 30 mm adjustment, PT port, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options. Although the 115 mm stroke is below the 300 mm side-load threshold, the robust 40 mm rod and M36x2 thread handle high side loads effectively, while the variable air cushions at both ends manage deceleration.
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 SAIJ160BX115-30S FAQ
At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster allows you to shorten the 115 mm nominal stroke by up to 30 mm, creating an adjustable travel window of 85 to 115 mm to fine-tune the end position without replacing the cylinder.
