About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-40S
The AirTAC SAIJ160X105-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the nominal 105 mm travel by up to 40 mm. This yields a precise 65-105 mm usable stroke window, enabling exact end-position tuning at commissioning without adding external stops. Belonging to the 160 mm bore class, it delivers substantial thrust, generating 18095 N of push force at 0.9 MPa.
Equipped with a standard carbon steel rod and PT tapered ports, this variant includes a magnet (-S) for position sensing with AirTAC CMSE reed and DMSE electronic switches. The extruded aluminum barrel incorporates sensor grooves on both sides, and the design omits the FB, CA, CB, and CR mounts, utilizing a reduced interface set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-40S Is Used
Variable End-Stop Setup
Dial in the exact 65 to 105 mm travel distance during machine commissioning to perfect end-of-stroke positioning without physical cylinder swaps.
Product Changeover Lines
Rapidly adapt downstream machinery stroke lengths when handling different package dimensions, leveraging the 40 mm adjustment range for quick size transitions.
Heavy Clamping Stations
Utilize the 14074 N push force at 0.7 MPa to securely hold heavy workpieces, fine-tuning the clamping reach to accommodate varied material thicknesses.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-40S the Right Cylinder?
Step down to the 125 mm bore if your application requires less force, as it provides 11045 N push at 0.9 MPa. Choose this adjustable SAIJ model over a fixed-stroke SAI cylinder when you need variable end-stops to accommodate product-size changeovers on a line. The rear adjuster acts purely as a travel stop to set deceleration; it is not a lock. For true load-holding without live air pressure, select the SAIL (air-released lock) or BSAI (clamp-lock) series. To match this ISO 15552 replacement exactly, verify the 160 mm bore, 105 mm stroke, 40 mm adjustment, PT ports, and the -S magnet requirement.
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 SAIJ160X105-40S FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder generates 18095 N of push force and 9425 N of pull force. It reaches a maximum force of 2050 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the effective travel from the 105 mm nominal stroke down to 65 mm. This creates a 65-105 mm adjustable window for fine-tuning the retract end position without swapping the cylinder.
