About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX275-40S
The AirTAC SAIJ160X275-40-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to fine-tune the retract end-position. With a 275 mm nominal stroke and a 40 mm adjustment range, it provides a usable travel window of 235-275 mm. This bore size delivers heavy thrust, pushing 14074 N at 0.7 MPa and pulling 9425 N at 0.5 MPa.
This unit is built with a SUS304 stainless steel rod (code B) for superior corrosion resistance and features a PT tapered port thread. It includes a magnet for position sensing, working seamlessly with AirTAC CMSE reed and DMSE solid-state switches mounted in the dual-side sensor grooves. The variable air cushions at both ends decelerate the 40 mm cushion length, but remember the rear adjuster is a travel stop, not a lock; it will not hold 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 SAIJ160BX275-40S Is Used
Heavy Press Tuning
Dial in the exact 235-275 mm press depth during setup to accommodate different material thicknesses without changing the cylinder.
Variable End Stops
Use the 40 mm rear adjuster to modify the retract position on the fly for product size changeovers on the line.
Machine Commissioning
Fine-tune the travel end-point during initial machine build to perfect timing sequences without installing external physical stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX275-40S the Right Cylinder?
Choose this 160 mm bore adjustable cylinder when you need to dial in exact end-stops during machine commissioning or product changeover without swapping components or adding external stops. For holding loads safely without live air, select a SAIL pneumatic lock or BSAI clamp-lock cylinder instead of relying on the adjuster.
This SAIJ160X275-40-S replaces ISO 15552 cylinders with a 160 mm bore, 275 mm stroke, 40 mm adjustment, PT G3/4 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and a magnet (-S). Because the 275 mm stroke is moderately long, ensure external guide rails support any heavy side-loads to prevent rod binding.
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 SAIJ160BX275-40S FAQ
The rear adjuster screw lets you shorten the 275 mm nominal stroke by up to 40 mm, creating a usable travel window of 235-275 mm. This allows precise end-position tuning during commissioning without replacing the cylinder.
