About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X155-40S
The AirTAC SAIJ160X155-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers massive thrust, offering 14074N push and 9425N pull forces at 0.7 MPa. The built-in rear stopper screw provides a usable travel window of 115 to 155 mm, allowing you to dial back the nominal stroke by up to 40 mm during commissioning without adding external stops.
Equipped with a magnet for position sensing, this unit supports AirTAC CMSE reed and DMSE electronic sensors housed in the dual-side barrel grooves. It features a robust 40 mm carbon steel rod with an M36x2 thread, providing high side-load resistance. The standard seals are TPU, but Viton H options are available for high-temperature environments up to 70 C.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X155-40S Is Used
Heavy Press Tuning
Dial in the exact 115-155 mm end position during machine setup to accommodate varying material thicknesses without swapping cylinders.
Product Changeover
Quickly adjust the retract distance on packaging lines when switching to a different product size, using the 40 mm trim window.
Automated Assembly
Leverage the 18095N pull force at 0.9 MPa to seat heavy components, fine-tuning the travel limit to prevent over-travel damage.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X155-40S the Right Cylinder?
Select this 160 mm bore when an 80 mm bore (3518N push at 0.5 MPa) is insufficient but a 200 mm bore is physically too large. The adjustable stroke is ideal for product changeovers on a line, letting operators fine-tune the retract end-position quickly. The rear adjuster acts purely as a travel stop and deceleration aid alongside the 50 mm air cushions; it does not hold the load without live air. For true load-holding, consider the SAIL or BSAI series.
As a dimensionally interchangeable ISO 15552 profile cylinder, replacement requires matching the 160 mm bore, 155 mm stroke, 40 mm adjustment, PT tapered ports, and the -S magnet. Mounting options include the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ160X155-40S FAQ
The rear adjuster screw lets you shorten the effective travel from the 155 mm nominal stroke down to 115 mm, providing a 40 mm tuning window. It acts as a mechanical stop and does not lock the load without continuous air pressure.
At 0.7 MPa, it provides 14074N of push force and 9425N of pull force. At the maximum 1.0 MPa operating pressure, it achieves 18095N push and 10053N pull.
