About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X110-40S
The AirTAC SAIJ80X110-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 70 to 110 mm for precise end-position tuning. Fitted with a carbon steel rod and a PT tapered port, it delivers 2513 N of push force and 2268 N of pull force at 0.5 MPa. The extruded aluminum barrel features sensor grooves on both sides, and because this unit includes a magnet (-S), it directly supports AirTAC CMSE reed and DMSE electronic solid-state switches for exact position verification.
This adjustable-stroke design allows you to dial in the retract end-position during commissioning or product changeover without swapping the cylinder or adding external stops. The rear adjuster acts purely as a mechanical travel stop to set the deceleration point alongside the variable air cushions; it does not hold the load without live air. For load-holding requirements, consider the SAIL or BSAI series. It uses the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR options.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X110-40S Is Used
Machine Changeover
Dial in the 70-110 mm travel window during product-size changeovers without physically replacing the cylinder or adding external stopper blocks.
Sensor-Verified Setup
Leverage the integrated magnet with AirTAC CMSE reed or DMSE electronic sensors to confirm the exact adjusted end-position on the assembly line.
Force-Tuned Clamping
Utilize the 2513 N push force at 0.5 MPa for firm holding and clamping tasks where the end-stop must be fine-tuned to the exact part dimensions.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X110-40S the Right Cylinder?
Choose this 80 mm bore when the 50 mm class (offering 982 N push at 0.5 MPa) is insufficient, but the 100 mm class (3927 N at 0.5 MPa) would be excessive. An adjustable stroke is ideal for variable end-stops and machine setups where a fixed-stroke SAI cylinder cannot accommodate product-size changes on the fly. When replacing an ISO 15552 unit, match the 80 mm bore, 110 mm nominal stroke, 40 mm adjustment, PT G3/8 port, and the -S magnet requirement. Since the stroke is under 300 mm, side-load stress is moderate, though the 25 mm rod and M20x1.5 thread handle typical loads well; always guide long unsupported loads externally.
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 SAIJ80 Adjustable Cylinder SAIJ80X110-40S FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At the maximum operating pressure of 1.0 MPa, the push force reaches 5026 N.
The rear adjuster allows you to shorten the 110 mm nominal stroke by up to 40 mm, creating a usable travel window of 70 to 110 mm. It functions as a mechanical stop to fine-tune the end position and does not lock the load without live air.
