Airtac SAIJ160 Adjustable Cylinder SAIJ160BX115-75S
The AirTAC SAIJ160 Adjustable Cylinder SAIJ160BX115-75S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 115mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX115-75S
It features a durable SUS304 stainless steel rod and a built-in magnet for position sensing. With a nominal stroke of 115mm and a 75mm adjustment code, you can fine-tune the effective travel down to a 40mm minimum, creating a highly flexible 40-115mm usable window without changing the physical cylinder length.
This adjustable travel capacity is ideal for product changeovers and commissioning setups where exact end positions vary. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. Note that the rear adjuster acts purely as a travel stop to decelerate the piston alongside the air cushions; it does not lock the load without live air pressure.

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 SAIJ160BX115-75S Is Used
Machine Setup & Changeover
Dial in the exact end-of-stroke position during product size changeovers using the 40-115mm adjustable travel window, eliminating the need to swap out physical spacers or cylinders.
Variable End-Stop Assembly
Utilize the SUS304 stainless steel rod and fine-tuned retraction point to assemble components of varying heights safely, relying on CMSE/DMSE sensors to confirm the adjusted stroke completion.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX115-75S the Right Cylinder?
If you need less force, stepping down to a 125mm bore yields 6136N at 0.5 MPa, whereas moving up to a 200mm bore provides 15708N. Choose the SAIJ adjustable-stroke design over a fixed SAI model when you need on-the-fly end-stop tuning during machine setup rather than fabricating external mechanical stops.
For an exact ISO 15552 dimensionally interchangeable replacement, match the 160mm bore, 115mm nominal stroke, 75mm adjustment range, PT tapered port threads, and the -S magnet option. Because this cylinder features a 40mm diameter rod with an M36x2 thread, it handles significant side loads, but any application approaching the maximum stroke limits should still incorporate an external guide rail to prevent premature seal wear. If your process requires true load-holding without continuous air pressure, pair this cylinder with an external rod lock or explore the SAIL or BSAI locking variants.
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 SAIJ160BX115-75S FAQ
The rear adjuster screw allows you to shorten the nominal 115mm stroke by up to 75mm, providing an effective adjustable travel window between 40mm and 115mm. The adjuster acts as a mechanical stop to tune the end position during setup, but it is not a lock and requires live air to hold the load.
